Library of Celsus. The Library of Celsus () is an ancient Roman building in Ephesus, Anatolia, now part of Selçuk, Turkey. The building was commissioned in the 110s A.D. by a consul, Gaius Julius Aquila, as a funerary monument for his father, former proconsul of Asia Tiberius Julius Celsus Polemaeanus, and completed during the reign of Hadrian, sometime after Aquila's death. The library is considered an architectural marvel, and is one of the only remaining examples of a library from the Roman Empire. The Library of Celsus was the third-largest library in the Roman world behind only Alexandria and Pergamum, believed to have.

Library of Celsus. held around twelve thousand scrolls. Celsus is buried in a crypt beneath the library in a decorated marble sarcophagus. The interior measured roughly 180 square metres (2,000 square feet).The interior of the library and its contents were destroyed in a fire that resulted either from an earthquake or a Gothic invasion in 262 A.D., and the façade by an earthquake in the tenth or eleventh century. It lay in ruins for centuries until the façade was re-erected by archaeologists between 1970 and 1978.## History.Celsus enjoyed a successful military and political career, having served as a commander in the Roman army.

Library of Celsus. before being elected to serve as a consul in Rome in 92 A.D. Celsus, a native of Sardis, was one of the first men from the Greek-speaking eastern provinces to serve as a consul, the highest elected office in imperial Rome. He was later appointed as proconsul, or governor, of Asia, the Roman province that covered roughly the same area as modern-day Turkey. Celsus's son Aquila commissioned the library in his honor, though it was not completed until after Aquila's death. An inscription records that Celsus left a large legacy of 25,000 denarii to pay for the library's reading material.The.

Library of Celsus. library operated as a public space for the city from its completion around 117–135 A.D. until 262. The main floor functioned as a reading room, lit by abundant natural light from the eastern windows. Shelves or "armaria" set into niches along the walls held papyrus book rolls that visitors could read, though borrowing would not have been permitted because copies of books were rare and labor-intensive to produce. Additional scrolls may have been held in free-standing book boxes placed around the room, in which case the library would have had a holding capacity of up to sixteen thousand scrolls.The interior.

Library of Celsus. and contents of the library were destroyed by fire in 262 C.E., though it remains unknown whether this fire was the result of natural disaster or a Gothic invasion, as it seems the city was struck by one of each that year. Only the façade survived, until an earthquake in eleventh or tenth century left it in ruins as well.Between 1970 and 1978, a reconstruction campaign was led by the German archaeologist Volker Michael Strocka. Strocka analysed the fragments that had been excavated by Austrian archaeologists between 1903 and 1904. In the meantime, some of the architectural elements had been.

Library of Celsus. acquired by museums in Vienna and Istanbul. The absent fragments had to be replaced by copies or left missing. Only the façade was rebuilt, while the rest of the building remains in ruin.## Architecture.The east-facing marble façade of the library is intricately decorated with botanical carvings and portrait statuary. Design features include acanthus leaves, scrolls, and fasces emblems, the latter being a symbol of magisterial power that alludes to Celsus's tenure as a consul. The library is built on a platform, with nine steps the width of the building leading up to three front entrances. These are surmounted by large.

Library of Celsus. windows, which may have been fitted with glass or latticework. Flanking the entrances are four pairs of Composite columns elevated on pedestals. A set of Corinthian columns stands directly above. The columns on the lower level frame four aediculae containing statues of female personifications of virtues: Sophia (wisdom), Episteme (knowledge), Ennoia (intelligence) and Arete (excellence). These virtues allude to the dual purpose of the structure, built to function as both a library and a mausoleum; their presence both implies that the man for whom it was built exemplified these four virtues, and that the visitor may cultivate these virtues in.

Library of Celsus. him or herself by taking advantage of the library's holdings. This type of façade with inset frames and niches for statues is similar to that of the "skene" found in ancient Greek theatres and is thus characterised as "scenographic". The columns on the second level flank four podia, paralleling the aediculae below, which held statues of Celsus and his son. A third register of columns may have been present in antiquity, though today only two remain.The interior of the building, which has yet to be restored, consisted of a single rectangular room measuring 17x11 m, with a central apse framed.

Library of Celsus. by a large arch at the far wall. The apse contained a podium for a statue, now lost, that likely depicted Celsus, although some scholars have suggested it was Minerva, goddess of wisdom. A crypt containing Celsus's sarcophagus was located beneath the floor of the apse. It was unusual in Roman culture for someone to be buried within a library or even within city limits, so this was a special honour for Celsus, reflecting his prominent role as a public official.The three remaining walls were lined with either two or three levels of niches measuring 2.55x1.1x0.58 m on average, which.

Library of Celsus. would have held the "armaria" to house the scrolls. These niches, which were backed with double walls, may have also had a function to control the humidity and protect the scrolls from the extreme temperature. The upper level was a gallery with a balcony overlooking the main floor, creating a lofty spatial effect inside. It could be reached via a set of stairs built into the walls, which added structural support. The ceiling was flat and may have had a central round oculus to provide more light.The design of the library, with its ornate, balanced façade, reflects the influence of.

Library of Celsus. Greek style on Roman architecture, which reached its height in the second century.## Portraiture of Celsus.The cuirassed statue of Celsus now in the Istanbul Archaeological Museum was one of three statues of the building's patron located on the second level of the façade. He is depicted with a strong jaw, curly hair, and a neat beard, Hellenizing portrait features that echo the stylistic choices of the building's façade. The style imitates traits of Hadrianic imperial portraiture, suggesting that it was sculpted after the lifetime of not only Celsus, but of his son Aquila as well. The choice to depict him.

Library of Celsus. in full armor suggests that Celsus's descendants considered his military career memorable and a source of pride.## Commemoration.The building's façade was depicted on the reverse of the Turkish 20 million lira banknote of 2001–2005 and of the 20 new lira banknote of 2005–2009.

Falun Mine. Falun Mine (Swedish: "Falu Gruva") was a mine in Falun, Sweden, that operated for a millennium from the 10th century to 1992. It produced as much as two-thirds of Europe's copper needs and helped fund many of Sweden's wars in the 17th century. Technological developments at the mine had a profound influence on mining globally for two centuries. The mine is now a museum and in 2001 was designated a UNESCO World Heritage Site.## History.There are no written accounts establishing exactly when mining operations at Falun Mine began. Archaeological and geological studies indicate, with considerable uncertainty, that mining operations started.

Falun Mine. sometime around the year 1000. No significant activities had begun before 850, but the mine was definitely operating by 1080. Objects from the 10th century have been found containing copper from the mine. In the beginning, operations were of a small scale, with local farmers gathering ore, smelting it, and using the metal for household needs.Around the time of Magnus III, king of Sweden from 1275 to 1290, a more professional operation began to take place. Nobles and foreign merchants from Lübeck had taken over from farmers. The merchants transported and sold the copper in Europe but also influenced the.

Falun Mine. copper was heating the rock via large fires, known as fire-setting. When the rock cooled down, it would become brittle and crack, allowing manual tools such as wedges and sledge hammers to be brought to bear. After the ore had been transported out of the mine it was roasted to reduce sulfur content in open hearths. The thick, poisonous smoke produced would be a distinguishing feature of the Falun area for centuries. After the roasting, the ore was smelted; the output of which was a copper rich material. The cycle of roasting and smelting was repeated several times until crude.

Falun Mine. copper was produced. This was the final output from the mine; further refinement took place at copper refineries elsewhere. This process was used without any major change for seven centuries, until the end of the 19th century. It is likely that the methods and technology for fire-setting and drainage were imported from German mines, such as in the Harz Mountains.## Free miners.The organizational structure of Falun Mine created under the 1347 charter was advanced for its time. Free miners owned shares of the operation, proportional to their ownership of copper smelters. The structure was precursor to modern joint stock companies,.

Falun Mine. and Stora Enso, the modern successor to the old mining company, is often referred to as the oldest joint stock company still operational in the world.## Golden era.In the 17th century, production capacity peaked. During this time, the output from the mine was used to fund various wars of Sweden during its great power era. The Privy Council of Sweden referred to the mine as the nation's treasury and stronghold. The point of maximum production occurred in 1650, with over 3,000 tonnes of copper produced.The mountain had been mined for nearly half a millennium towards the end of its golden.

Falun Mine. is one of the great wonders of Sweden but as horrible as hell itself". Linnaeus' description of the environment the miners worked in is as follows: "Soot and darkness surrounded them on all sides. Stones, gravel, corrosive vitriol, drips, smoke, fumes, heat, dust, were everywhere".## Economic impact.Sweden had a virtual monopoly on copper which it retained throughout the 17th century. The only other country with a comparable copper output was Japan, but European imports from Japan were insignificant. In 1690, Erik Odhelius, a prominent metallurgist, was dispatched by the King to survey the European metal market. Although copper production had.

Falun Mine. already begun to decline by the time he made his report, something Odhelius made no secret of, he stated, "For the production of copper Sweden has always been like a mother, and although in many places within and without Europe some copper is extracted it counts for nothing next to the abundance of Swedish copper".By modern standards, however, the output was not large. Peak production barely reached 3,000 tonnes of copper per year, falling to less than 2,000 tonnes by 1665; from 1710 to 1720 it was barely 1,000 tonnes per year. Present worldwide copper production is 18.3 million tons.

Falun Mine. per year; Chuquicamata, a modern copper mine in Chile, has maintained an annual output exceeding 500,000 tonnes for decades.## Modern history.Copper production declined during the 18th century, and the mining company began diversifying. It supplemented copper extraction with iron and timber production. Production of the iconic falu red paint began in earnest. In the 19th century, iron and forest products continued to grow in their importance. In 1881 gold was discovered in Falun Mine, resulting in a short-lived gold rush. A total of 5 tonnes of gold would eventually be produced.By the late 20th century, the mine was no longer.

Mopalia muscosa. Mopalia muscosa, the mossy chiton, is a species of chiton, a polyplacophoran, an eight-plated marine mollusk. It is a northeastern Pacific species which occurs from British Columbia, Canada, to Baja California Mexico.This species is found in the middle and lower intertidal zone on exposed rocky shores. "Mopalia muscosa" can be 40 to 55 (mm) in length. Mossy chitons are often covered by algae, barnacles, and limpets. The chiton's girdle is covered with coarse hair-like bristles or "setae".The visible exterior of the chiton's eight shell plates are typically a drab brown or grey-green, however on the underside the shell plates have.

Mopalia muscosa. a vibrant turquoise blue color. Some mossy chitons are biofluorescent mainly around the girdle and may show a bright glowing green color under ultra-violet or blue light. Mossy chitons typically move about at night or when covered by a high tide in order to graze on the red and green algae of which their diet consists. Young chitons have a planktonic stage and later metamorphose and settle on the bottom as adults.## References.

Springbok. The springbok (Antidorcas marsupialis) is a medium-sized antelope found mainly in south and southwest Africa. The sole member of the genus "Antidorcas", this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches 71 to 86 (cm) at the shoulder and weighs between 27 and 42 (kg). Both sexes have a pair of black, 35 to 50 (cm) long horns that curve backwards. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light-brown coat.

Springbok. to the long-term survival of the species are known; the springbok, in fact, is one of the few antelope species considered to have an expanding population. They are popular game animals, and are valued for their meat and skin. The springbok is the national animal of South Africa.## Etymology.The common name "springbok", first recorded in 1775, comes from the Afrikaans words "spring" ("jump") and "bok" ("antelope" or "goat"). The scientific name of the springbok is "Antidorcas marsupialis". "Anti" is Greek for "opposite", and "dorcas" for "gazelle" – identifying the animal as not a gazelle. The specific epithet "marsupialis" comes from.

Springbok. the Latin "marsupium" ("pocket"), and refers to a pocket-like skin flap which extends along the midline of the back from the tail, which distinguishes the springbok from true gazelles.## Taxonomy and evolution.The springbok, in the family Bovidae, was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780, who assigned the genus "Antilope" (blackbuck) to the springbok. In 1845, Swedish zoologist Carl Jakob Sundevall placed the springbok as the sole living member of the genus "Antidorcas".## Subspecies.Three subspecies of "Antidorcas marsupialis" are recognised: "A. m. angolensis" – Occurs in Benguela and Moçâmedes (southwestern Angola). "A. m. hofmeyri.

Springbok. – Occurs in Berseba and Great Namaqualand (southwestern Africa). Its range lies north of the Orange River, stretching from Upington and Sandfontein through Botswana to Namibia. "A. m. marsupialis" – Its range lies south of the Orange River, extending from the northeastern Cape of Good Hope to the Free State and Kimberley.## Evolution.Fossil springbok are known from the Pliocene; the antelope appears to have evolved about three million years ago from a gazelle-like ancestor. Three fossil species of "Antidorcas" have been identified, in addition to the extant form, and appear to have been widespread across Africa. Two of these, "A.

Pomegranate. The pomegranate ("Punica granatum") is a fruit-bearing deciduous shrub in the family Lythraceae, subfamily Punicoideae, that grows between 5 and 10 (m) tall.The pomegranate was originally described throughout the Mediterranean region. It was introduced into Spanish America in the late 16th century and into California by Spanish settlers in 1769.The fruit is typically in season in the Northern Hemisphere from October to February, and in the Southern Hemisphere from March to May. As intact sarcotestas or juice, pomegranates are used in baking, cooking, juice blends, meal garnishes, smoothies, and alcoholic beverages, such as cocktails and wine.Pomegranates are widely cultivated throughout.

Walrus. Norse word ('horse'). For example, the Old Norse word means 'horse-whale' and is thought to have been passed in an inverted form to both Dutch and the dialects of northern Germany as and . An alternative theory is that it comes from the Dutch words 'shore' and 'giant'.The species name "rosmarus" is Scandinavian. The Norwegian manuscript "Konungs skuggsjá", thought to date from around AD 1240, refers to the walrus as in Iceland and in Greenland (walruses were by now extinct in Iceland and Norway, while the word evolved in Greenland). Several place names in Iceland, Greenland and Norway may originate.

Walrus. Tusks and dentition.While this was not true of all extinct walruses, the most prominent feature of the living species is its long tusks. These are elongated canines, which are present in both male and female walruses and can reach a length of 1 m (3 ft 3 in) and weigh up to 5.4 kg (12 lb). Tusks are slightly longer and thicker among males, which use them for fighting, dominance and display; the strongest males with the largest tusks typically dominate social groups. Tusks are also used to form and maintain holes in the ice and aid the walrus in.

Walrus. Vibrissae (whiskers).Surrounding the tusks is a broad mat of stiff bristles ("mystacial vibrissae"), giving the walrus a characteristic whiskered appearance. There can be 400 to 700 vibrissae in 13 to 15 rows reaching 30 cm (12 in) in length, though in the wild they are often worn to much shorter lengths due to constant use in foraging. The vibrissae are attached to muscles and are supplied with blood and nerves, making them highly sensitive organs capable of differentiating shapes 3 (mm) thick and 2 (mm) wide.## Skin.Aside from the vibrissae, the walrus is sparsely covered with fur and appears bald.

Walrus. walrus numbers have again declined. Early aerial censuses of Pacific walrus conducted at five-year intervals between 1975 and 1985 estimated populations of above 220,000 in each of the three surveys.In 2006, the population of the Pacific walrus was estimated to be around 129,000 on the basis of an aerial census combined with satellite tracking. There were roughly 200,000 Pacific walruses in 1990.The much smaller population of Atlantic walruses ranges from the Canadian Arctic, across Greenland, Svalbard, and the western part of Arctic Russia. There are eight hypothetical subpopulations of Atlantic walruses, based largely on their geographical distribution and movements: five.

Walrus. A genetically distinct population existed in Iceland that was wiped out after Norse settlement around 1213–1330 AD.The isolated population of Laptev Sea walruses is confined year-round to the central and western regions of the Laptev Sea, the eastmost regions of the Kara Sea, and the westmost regions of the East Siberian Sea. The current population of these walruses has been estimated to be between 5,000 and 10,000.Even though walruses can dive to depths beyond 500 meters, they spend most of their time in shallow waters (and the nearby ice floes) hunting for food.In March 2021, a single walrus, nicknamed Wally.

Walrus. while giving birth and aggregating in the reproductive period. Thinner pack ice over the Bering Sea has reduced the amount of resting habitat near optimal feeding grounds. This more widely separates lactating females from their calves, increasing nutritional stress for the young and lower reproductive rates. Reduced coastal sea ice has also been implicated in the increase of stampeding deaths crowding the shorelines of the Chukchi Sea between eastern Russia and western Alaska. Analysis of trends in ice cover published in 2012 indicate that Pacific walrus populations are likely to continue to decline for the foreseeable future, and shift further.

Walrus. the Inuit goddess Sedna. Both in Chukotka and Alaska, the aurora borealis is believed to be a special world inhabited by those who died by violence, the changing rays representing deceased souls playing ball with a walrus head.Most of the distinctive 12th-century Lewis Chessmen from northern Europe are carved from walrus ivory, though a few have been found to be made of whales' teeth.## Literature.Because of its distinctive appearance, great bulk, and immediately recognizable whiskers and tusks, the walrus also appears in the popular cultures of peoples with little direct experience with the animal, particularly in English children's literature.

Hanauma Bay. Hanauma (; )is a marine embayment formed within a tuff ring and located along the southeast coast of the Island of Oahu in the Hawaii Kai neighborhood of East Honolulu, in the Hawaiian Islands.Hanauma is one of the most popular tourist destinations on the Island and has suffered somewhat from overtourism. At one time, this popular tourist destination accommodated over three million visitors per year.

The bay was used as a recreational area by "aliʻi" (Hawaiian nobility), including King Kamehameha and Queen Ka‘ahumanu, who fished, entertained visitors, and sponsored games there. It was also used as a layover and as a navigational lookout point, since the waters between Oʻahu and Molokaʻi are at times difficult.Hanauma Bay was purchased from the Bernice Pauahi Bishop estate by the City and County of Honolulu, and subsequently opened for public use.

Seven Wonders of the Ancient World. The Seven Wonders of the Ancient World (also known as the Seven Wonders of the World or simply the Seven Wonders) is a list of seven notable structures present during classical antiquity. The first known list of seven wonders dates back to the 2nd–1st century BC.While the entries have varied over the centuries, the seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located.

Seven Wonders of the Ancient World. in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, still remains standing, with the others being destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. ## Background.Alexander the Great's conquest of much of the western world in the 4th century BC gave Hellenistic travellers access to the civilizations of the Egyptians, Persians, and Babylonians. Impressed and captivated by the landmarks.

The surviving manuscript is incomplete, missing its last pages. Still, from the preamble text, we can conclude that the list of seven sights exactly matches Antipater's (the preamble mentions the location of Halicarnassus, but the pages describing the seventh wonder, presumably the Mausoleum, are missing).Earlier and later lists by the historian Herodotus ( BC– BC) and the poet Callimachus of.

Their architectural and artistic features were imitated throughout the Hellenistic world and beyond.The Greek influence in Roman culture, and the revival of Greco-Roman artistic styles during the Renaissance caught the imagination of European artists and travellers. Paintings and sculptures alluding to Antipater's list were made, while significant numbers of adventurers travelled to.

Fossil and molecular data suggest the genus "Carya" may have diversified during the Miocene. Modern "Carya" first appear in Oligocene strata 34 million years ago. Recent discoveries of "Carya" fruit fossils further support the hypothesis that the genus has long been a member of Eastern North American landscapes, however its range has contracted and Carya is no longer extant west of the.

Hickory. Rocky Mountains.Fossils of early hickory nuts show simpler, thinner shells than modern species with the exception of pecans, suggesting that the trees gradually developed defenses to rodent seed predation. During this time, the genus had a distribution across the Northern Hemisphere, but the Pleistocene Ice Age beginning 2 million years ago obliterated it from Europe. The distribution of Carya in North America also contracted and it completely disappeared from the continent west of the Rocky Mountains. Since fossil records show North America as having the largest number of Juglandaceae species, it is likely that the genus originated there and later.

Hickory. spread to Europe and Asia.## Fruit.Some fruits are borderline and difficult to categorize. Hickory nuts ("Carya") and walnuts ("Juglans") in the Juglandaceae family grow within an outer husk; these fruits are sometimes considered to be drupes or drupaceous nuts, rather than true botanical nuts. "Tryma" is a specialized term for such nut-like drupes.## Nutrition.Dried hickory nuts are 3% water, 18% carbohydrates, 13% protein, and 64% fats (table). In a 100 gram (3.5 oz) reference amount, dried hickory nuts supply 657 calories, and are a rich source (20% or more of the Daily Value, DV) of several B vitamins and dietary.

Hickory. regarded by some as the finest nut trees. Pecans are the most important nut tree native to North America.When cultivated for their nuts, clonal (grafted) trees of the same cultivar cannot pollinate each other because of their self-incompatibility. Two or more cultivars must be planted together for successful pollination. Seedlings (grown from hickory nuts) will usually have sufficient genetic variation. Hican WalnutPhilips, Roger.

Australian wood duck. The Australian wood duck, maned duck or maned goose ("Chenonetta jubata") is a dabbling duck found throughout much of Australia. It is the only living species in the genus Chenonetta. Traditionally placed in the subfamily Anatinae (dabbling ducks), it might belong to the subfamily Tadorninae (shelducks); the ringed teal may be its closest living relative.## Taxonomy.The Australian wood duck was first described by the English ornithologist John Latham in 1801 under the binomial name "Anas jubata".The flightless New Zealand species "Chenonetta finschi" (Finsch's duck) which was formerly believed to constitute a monotypic genus ("Euryanas") has been determined to belong to.

The Australian wood duck is found in grasslands, open woodlands, wetlands, flooded pastures and along the coast in inlets and bays. It is also common on farmland with dams, as well as around rice fields, sewage ponds and in urban parks. It will often be found around deeper lakes that may be unsuitable for other waterbirds' foraging, as it prefers to forage on land. It has been recorded as a vagrant in New Zealand, although in 2015 and.

Nests are made with a pile of down.## Breeding.This duck nests in a tree cavity laying 9–11 cream-white eggs, similar to the Mandarin ducks. The female incubates them while the male stands guard. Once the ducklings are ready to leave the nest, the female flies to the ground and the duckling will leap to the ground and follow their parents. The males also secure their ducklings closely along with the females.## Feeding.The Australian wood duck eats grasses, grains, clover and.

Australian wood duck. other herbs, and occasionally, insects. It is rarely seen on open water, preferring to forage by dabbling in shallow water, or in grasslands and crops.## Similar species.The Australian wood duck can be distinguished from pygmy geese, Nettapus spp, which are smaller, have bold white face markings and are usually seen on water. Whistling ducks, Dendrocygna spp, have longer legs and necks, larger more duck-like bills and tend to walk more upright.

Caltha palustris. Caltha palustris, known as marsh-marigold and kingcup, is a small to medium size perennial herbaceous plant of the buttercup family, native to marshes, fens, ditches and wet woodland in temperate regions of the Northern Hemisphere. It flowers between April and August, dependent on altitude and latitude, but occasional flowers may occur at other times.## Description."Caltha palustris" is a 10 – 80 (cm) high, hairless, fleshy, perennial, herbaceous plant that dies down in autumn and overwinters with buds near the surface of the marshy soil. The plants have many, 2 – 3 (mm) thick strongly branching roots. Its flowering stems are.

It can be found in much of the northeastern United States.## Ecology.The marsh-marigold grows in places with oxygen-rich water near the surface of the soil. It likes richer soils, but dislikes application of fertilizer and avoids high concentrations of phosphate and ammonium, and is also shy of brackish water. It is often associated with seepage that is rich in iron, because iron ions react with phosphate, thus making it unavailable for plants. The resulting insoluble.

Around the edge of lakes and rivers it grows between reeds, and it can be found in black alder coppices and other regularly flooded and always moist forests. When it is present it often visually dominates when it is in bloom. It also used to be common on wet meadows, but due to agricultural rationalization it is now limited to ditches.It is a component of purple moor grass and rush pastures – a type of Biodiversity Action Plan habitat in the UK.

American red fox. The American red fox ("Vulpes vulpes fulva") is a North American subspecies of the red fox. It is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, occurring in North America. It is listed as least concern by the IUCN. This subspecies is most likely the ancestor of the domesticated silver fox.## North American colonization and native status.Current literature discusses whether or not the red fox is native to North America, with some research suggesting that nearly all red fox populations in North America are not native. "Vulpes vulpes " is.

American red fox. usually seen either as an exotic species introduced by Europeans during the colonization of the North American continent or as a hybrid between European and North American red foxes. While it is claimed that "Vulpes vulpes fulva" stems from a non-native population that spread westward from European introduction, a historical analysis of firsthand accounts does not support this claim.Phylogeographical and genetic analysis of the American red fox suggests that red foxes first migrated to North America during the Illinoian glaciation (300,000 to 130,000 years before present) and spread southward. More recently, the Wisconsin glaciation (100,000 to 10,000 before present) separated.

American red fox. the North American red fox population into two distinct areas. North American red foxes are genetically distinctive from their Eurasian counterparts. Despite claims of historical translocations from Europe, modern red fox populations in the United States' southeastern region have been shown to be native to North America. DNA comparisons show that the eastern American red fox is closely related to native populations in Canada and the northeastern region of the United States and is, therefore, the result of natural range expansions and not an invasive species from Europe as was previously thought. Range expansions seen recently may be connected to.

American red fox. anthropogenic landscape change and not the spread of exotic European populations.The native status of the American red fox has been demonstrated by current research, which has important implications for management strategies. Previous classifications and taxonomic uncertainties frame populations of "Vulpes fulva" as a non-native invasive species that can cause declines in the populations of native species and in carrying capacities and can populate regions at higher densities. The identification of the origins of the North American red fox populations is crucial in conservation efforts aimed at native vs. non-native species. In 2014, Mark J. Statham among others released a study.

American red fox. that supports "Vulpes fulva" as a separate species from the Old World "Vulpes vulpes".## Taxonomy.The North American red foxes have been traditionally considered either as subspecies of the Old World red foxes or subspecies of their own species, "V. fulva". Due to the opinion that North American red foxes were introduced from Europe, all North American red foxes have been seen as conspecific with "V. vulpes"; however, genetic analyses of global red fox haplotypes indicates that the North American red foxes have been genetically isolated from the Old World populations for 400,000 years, prompting possible application of "V. fulva" to.

American red fox. all North American red foxes. Castello (2018) has formalized treatment of "Vulpes fulva" as a separate species from the Old World "Vulpes vulpes".## Origin.Red foxes colonized the North American continent in two waves: before or during the Illinoian glaciation and during the Wisconsinan glaciation. Gene mapping demonstrates that red foxes in North America have been isolated from their Old World counterparts for over 400,000 years, thus raising the possibility that speciation has occurred. In the far north, red fox fossils have been found in Sangamonian deposits in the Fairbanks District and Medicine Hat. Fossils dating from the Wisconsian are present.

American red fox. in 25 sites in Arkansas, California, Colorado, Idaho, Missouri, New Mexico, Tennessee, Texas, Virginia and Wyoming. Although they ranged far south during the Wisconsinan, the onset of warm conditions shrank their range toward the north and they have only recently reclaimed their former American ranges because of human-induced environmental changes. Genetic testing indicates two distinct red fox refugia exist in North America, which have been separated since the Wisconsinan. The northern (or boreal) refugium occurs in Alaska and western Canada and consists of the large subspecies "V. v. alascensis", "V. v. abietorum", "V. v. regalis" and "V. v. rubricosa". The.

American red fox. southern (or montane) refugium occurs in the sub-alpine parklands and alpine meadows of the Rocky Mountains, the Cascade Range and the Sierra Nevada and consists of the small subspecies "V. v. cascadensis", "V. v. macroura", "V. v. necator" and "V. v. patwin". The latter clade has been separated from all other red fox populations since the last glacial maximum and may possess unique ecological or physiological adaptations.Although European foxes ("V. v. crucigera") were introduced to portions of the United States in the 1900s, recent genetic investigation indicates an absence of European fox haplotypes in any North American populations. Also, introduced.

American red fox. eastern American red foxes have colonized southern California, the San Joaquin Valley and the San Francisco Bay Area, but appear to have mixed with the Sacramento Valley red fox ("V. v. patwin") only in a narrow hybrid zone. In addition, no evidence is seen of interbreeding of eastern American red foxes in California with the montane Sierra Nevada red fox ("V. v. necator") or other populations in the intermountain West (between the Rocky Mountains to the east and the Cascade and Sierra Nevada Mountains to the west).## Subspecies.Castelló recognized nine valid subspecies of the American red fox, as listed below:##.

American red fox. Habitat."Vulpes vulpes fulva" inhabits the entire region of the United States east of the Rocky Mountains except the southern Great Plains and southern Texas. The eastern American red fox generally prefers mixed vegetation communities that occur on edge habitats with a high level of diversity. In developed areas, the eastern American red fox will inhabit areas that offer a combination of woodland and agricultural land.## Diet, hunting, and feeding behavior.The American red fox has a primarily carnivorous diet dominated by small mammals. However, as an opportunistic species they will adopt an omnivorous diet that includes plants, fruits, berries, birds, insects.

Fresnel lens. A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships."The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens.

Fresnel lens. was first proposed by Count Buffon and independently reinvented by Fresnel. The "catadioptric" form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.## Description.The Fresnel lens reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. An ideal Fresnel lens would have an infinite number of sections. In each section, the overall.

Fresnel lens. thickness is decreased compared to an equivalent simple lens. This effectively divides the continuous surface of a standard lens into a set of surfaces of the same curvature, with stepwise discontinuities between them.In some lenses, the curved surfaces are replaced with flat surfaces, with a different angle in each section. Such a lens can be regarded as an array of prisms arranged in a circular fashion with steeper prisms on the edges and a flat or slightly convex center. In the first (and largest) Fresnel lenses, each section was actually a separate prism. 'Single-piece' Fresnel lenses were later produced, being.

Fresnel lens. used for automobile headlamps, brake, parking, and turn signal lenses, and so on. In modern times, computer-controlled milling equipment (CNC) or 3-D printers might be used to manufacture more complex lenses.Fresnel lens design allows a substantial reduction in thickness (and thus mass and volume of material) at the expense of reducing the imaging quality of the lens, which is why precise imaging applications such as photography usually still use larger conventional lenses.Fresnel lenses are usually made of glass or plastic; their size varies from large (old historical lighthouses, meter size) to medium (book-reading aids, OHP viewgraph projectors) to small (TLR/SLR.

Fresnel lens. camera screens, micro-optics). In many cases they are very thin and flat, almost flexible, with thicknesses in the 1 to 5 (mm) range.Most modern Fresnel lenses consist only of refractive elements. Lighthouse lenses, however, tend to include both refracting and reflecting elements, the latter being "outside" the metal rings seen in the photographs. While the inner elements are sections of refractive lenses, the outer elements are reflecting prisms, each of which performs two refractions and one total internal reflection, avoiding the light loss that occurs in reflection from a silvered mirror.## Lighthouse lens sizes.Fresnel designed six sizes of lighthouse lenses,.

Fresnel lens. divided into four "orders" based on their size and focal length. In modern use, these are classified as first through sixth order. An intermediate size between third and fourth order was added later, as well as sizes above first order and below sixth.A first-order lens has a focal length of 920 (mm) and stands about 2.59 (m) high, and 1.8 (m) wide. The smallest (sixth) order has a focal length of 150 (mm) and a height of 433 (mm).The largest Fresnel lenses are called hyperradiant (or hyper-radial). One such lens was on hand when it was decided to build and.

Fresnel lens. outfit the Makapuu Point Light in Hawaii. Rather than order a new lens, the huge optic construction, 12 (ft) tall and with over a thousand prisms, was used there.## Types.There are two main types of Fresnel lens: "imaging" and "non-imaging". Imaging Fresnel lenses use segments with curved cross-sections and produce sharp images, while non-imaging lenses have segments with flat cross-sections, and do not produce sharp images. As the number of segments increases, the two types of lens become more similar to each other. In the abstract case of an infinite number of segments, the difference between curved and flat segments.

This type of lens produces a sharp image, although not quite as clear as the equivalent simple spherical lens due to diffraction at the edges of the ridges.Cylindrical: A cylindrical Fresnel lens is equivalent to a simple cylindrical lens, using straight segments with circular cross-section, focusing light on a single line. This type produces a sharp image, although not quite as clear as the equivalent simple cylindrical lens due.

Such a lens can focus light on a small spot, but does not produce a sharp image. These lenses have application in solar power, such as focusing sunlight on a solar panel. Fresnel lenses may be used as components of Köhler illumination optics resulting in very effective nonimaging optics Fresnel-Köhler (FK) solar concentrators.Linear: A non-imaging linear Fresnel lens uses straight segments whose cross sections are straight lines rather than arcs. These lenses focus.

They are also used to correct several visual disorders, including ocular-motility disorders such as strabismus. Fresnel lenses have been used to increase the visual size of CRT displays in pocket televisions, notably the Sinclair TV80. They are also used in traffic lights.Fresnel lenses are used in left-hand-drive European lorries entering the UK and Republic of Ireland (and vice versa,.

Fresnel lens. right-hand-drive Irish and British trucks entering mainland Europe) to overcome the blind spots caused by the driver operating the lorry while sitting on the wrong side of the cab relative to the side of the road the car is on. They attach to the passenger-side window.Another automobile application of a Fresnel lens is a rear view enhancer, as the wide view angle of a lens attached to the rear window permits examining the scene behind a vehicle, particularly a tall or bluff-tailed one, more effectively than a rear-view mirror alone.Multi-focal Fresnel lenses are also used as a part of retina.

Fresnel lens. identification cameras, where they provide multiple in- and out-of-focus images of a fixation target inside the camera. For virtually all users, at least one of the images will be in focus, thus allowing correct eye alignment.Fresnel lenses have also been used in the field of popular entertainment. The British rock artist Peter Gabriel made use of them in his early solo live performances to magnify the size of his head, in contrast to the rest of his body, for dramatic and comic effect. In the Terry Gilliam film "Brazil", plastic Fresnel screens appear ostensibly as magnifiers for the small CRT.

Fresnel lens. monitors used throughout the offices of the Ministry of Information. However, they occasionally appear between the actors and the camera, distorting the scale and composition of the scene to humorous effect. The Pixar movie Wall-E features a Fresnel lens in the scenes where the protagonist watches the musical Hello, Dolly! magnified on an iPod.## Photography.Canon and Nikon have used Fresnel lenses to reduce the size of telephoto lenses. Photographic lenses that include Fresnel elements can be much shorter than corresponding conventional lens design. Nikon calls the technology "Phase Fresnel".The Polaroid SX-70 camera used a Fresnel reflector as part of its.

Fresnel lens. viewing system.View and large format cameras can utilize a Fresnel lens in conjunction with the ground glass, to increase the perceived brightness of the image projected by a lens onto the ground glass, thus aiding in adjusting focus and composition.## Illumination.High-quality glass Fresnel lenses were used in lighthouses, where they were considered state of the art in the late 19th and through the middle of the 20th centuries; most lighthouses have now retired glass Fresnel lenses from service and replaced them with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. Lighthouse Fresnel lens systems.

Fresnel lens. typically include extra annular prismatic elements, arrayed in faceted domes above and below the central planar Fresnel, in order to catch all light emitted from the light source. The light path through these elements can include an internal reflection, rather than the simple refraction in the planar Fresnel element. These lenses conferred many practical benefits upon the designers, builders, and users of lighthouses and their illumination. Among other things, smaller lenses could fit into more compact spaces. Greater light transmission over longer distances, and varied patterns, made it possible to triangulate a position.Perhaps the most widespread use of Fresnel lenses,.

Fresnel lens. for a time, occurred in automobile headlamps, where they can shape the roughly parallel beam from the parabolic reflector to meet requirements for dipped and main-beam patterns, often both in the same headlamp unit (such as the European H4 design). For reasons of economy, weight, and impact resistance, newer cars have dispensed with glass Fresnel lenses, using multifaceted reflectors with plain polycarbonate lenses. However, Fresnel lenses continue in wide use in automobile tail, marker, and reversing lights.Glass Fresnel lenses also are used in lighting instruments for theatre and motion pictures (see Fresnel lantern); such instruments are often called simply "Fresnels".

Fresnel lens. The entire instrument consists of a metal housing, a reflector, a lamp assembly, and a Fresnel lens. Many Fresnel instruments allow the lamp to be moved relative to the lens' focal point, to increase or decrease the size of the light beam. As a result, they are very flexible, and can often produce a beam as narrow as 7° or as wide as 70°. The Fresnel lens produces a very soft-edged beam, so is often used as a wash light. A holder in front of the lens can hold a colored plastic film ("gel") to tint the light or wire.

Fresnel lens. screens or frosted plastic to diffuse it. The Fresnel lens is useful in the making of motion pictures not only because of its ability to focus the beam brighter than a typical lens, but also because the light is a relatively consistent intensity across the entire width of the beam of light.Aircraft carriers and naval air stations typically use Fresnel lenses in their optical landing systems. The "meatball" light aids the pilot in maintaining proper glide slope for the landing. In the center are amber and red lights composed of Fresnel lenses. Although the lights are always on, the angle.

Fresnel lens. of the lens from the pilot's point of view determines the color and position of the visible light. If the lights appear above the green horizontal bar, the pilot is too high. If it is below, the pilot is too low, and if the lights are red, the pilot is very low.Fresnel lenses are also commonly used in searchlights, spotlights, and flashlights.## Projection.The use of Fresnel lenses for image projection reduces image quality, so they tend to occur only where quality is not critical or where the bulk of a solid lens would be prohibitive. Cheap Fresnel lenses can be.

Fresnel lens. stamped or molded of transparent plastic and are used in overhead projectors and projection televisions.Fresnel lenses of different focal lengths (one collimator, and one collector) are used in commercial and DIY projection. The collimator lens has the lower focal length and is placed closer to the light source, and the collector lens, which focuses the light into the triplet lens, is placed after the projection image (an active matrix LCD panel in LCD projectors). Fresnel lenses are also used as collimators in overhead projectors.## Solar power.Since plastic Fresnel lenses can be made larger than glass lenses, as well as being.

Fresnel lens. much cheaper and lighter, they are used to concentrate sunlight for heating in solar cookers, in solar forges, and in solar collectors used to heat water for domestic use. They can also be used to generate steam or to power a Stirling engine.Fresnel lenses can concentrate sunlight onto solar cells with a ratio of almost 500:1. This allows the active solar-cell surface to be reduced, lowering cost and allowing the use of more efficient cells that would otherwise be too expensive. In the early 21st century, Fresnel reflectors began to be used in concentrating solar power (CSP) plants to concentrate.

Fresnel lens. solar energy. One application was to preheat water at the coal-fired Liddell Power Station, in Hunter Valley Australia.Fresnel lenses can be used to sinter sand, allowing 3D printing in glass.## History.## Forerunners.Augustin-Jean Fresnel was not the first person to focus a lighthouse beam using a lens. That distinction apparently belongs to the London glass-cutter Thomas Rogers, who proposed the idea to Trinity House in 1788. The first Rogers lenses, 53cm in diameter and 14cm thick at the center, were installed at the Old Lower Lighthouse at Portland Bill in 1789. Behind each lamp was a back-coated spherical glass mirror, which.

Fresnel lens. reflected rear radiation back through the lamp and into the lens. Further samples were installed at Howth Baily, North Foreland, and at least four other locations by 1804. But much of the light was wasted by absorption in the glass.Nor was Fresnel the first to suggest replacing a convex lens with a series of concentric annular prisms, to reduce weight and absorption. In 1748, Count Buffon proposed grinding such prisms as steps in a single piece of glass. In 1790 (although secondary sources give the date as 1773 or 1788), the Marquis de Condorcet suggested that it would be easier.

Fresnel lens. to make the annular sections separately and assemble them on a frame; but even that was impractical at the time. These designs were intended not for lighthouses, but for burning glasses. David Brewster, however, proposed a system similar to Condorcet's in 1811, and by 1820 was advocating its use in British lighthouses.## Fresnel's contributions.The French (Commission of Lighthouses) was established by Napoleon in 1811, and placed under the authority of Fresnel's employer, the Corps of Bridges and Roads. As the members of the commission were otherwise occupied, it achieved little in its early years. But on 21 June 1819—three months.

Fresnel lens. after winning the physics of the Academy of Sciences for his celebrated memoir on diffraction—Fresnel was "temporarily" seconded to the commission on the recommendation of François Arago (a member since 1813), to review possible improvements in lighthouse illumination.By the end of August 1819, unaware of the Buffon-Condorcet-Brewster proposal, Fresnel made his first presentation to the commission, recommending what he called ('lenses by steps') to replace the reflectors then in use, which reflected only about half of the incident light. Much to Fresnel's embarrassment, one of the assembled commissioners, Jacques Charles, recalled Buffon's suggestion. However, whereas Buffon's version was biconvex and.

Fresnel lens. in one piece, Fresnel's was plano-convex and made of multiple prisms for easier construction. With an official budget of 500 francs, Fresnel approached three manufacturers. The third, François Soleil, found a way to remove defects by reheating and remolding the glass. Arago assisted Fresnel with the design of a modified Argand lamp with concentric wicks (a concept that Fresnel attributed to Count Rumford), and accidentally discovered that fish glue was heat-resistant, making it suitable for use in the lens. The prototype, finished in March 1820, had a square lens panel 55cm on a side, containing 97 polygonal (not annular) prisms—and.

Fresnel lens. so impressed the Commission that Fresnel was asked for a full eight-panel version. This model, completed a year later in spite of insufficient funding, had panels 76cm square. In a public spectacle on the evening of 13 April 1821, it was demonstrated by comparison with the most recent reflectors, which it suddenly rendered obsolete.Soon after this demonstration, Fresnel published the idea that light, including apparently unpolarized light, consists exclusively of transverse waves, and went on to consider the implications for double refraction and partial reflection.Fresnel acknowledged the British lenses and Buffon's invention in a memoir read on 29 July 1822.

Fresnel lens. and printed in the same year. The date of that memoir may be the source of the claim that Fresnel's lighthouse advocacy began two years later than Brewster's; but the text makes it clear that Fresnel's involvement began no later than 1819.Fresnel's next lens was a rotating apparatus with eight "bull's-eye" panels, made in annular arcs by Saint-Gobain, giving eight rotating beams—to be seen by mariners as a periodic flash. Above and behind each main panel was a smaller, sloping bull's-eye panel of trapezoidal outline with trapezoidal elements. This refracted the light to a sloping plane mirror, which then reflected.

Fresnel lens. it horizontally, 7 degrees ahead of the main beam, increasing the duration of the flash. Below the main panels were 128 small mirrors arranged in four rings, stacked like the slats of a louver or Venetian blind. Each ring, shaped like a frustum of a cone, reflected the light to the horizon, giving a fainter steady light between the flashes. The official test, conducted on the unfinished on 20 August 1822, was witnessed by the Commission—and by Louis XVIII and his entourage—from 20 (mi) away. The apparatus was stored at Bordeaux for the winter, and then reassembled at Cordouan Lighthouse.

Fresnel lens. under Fresnel's supervision—in part by Fresnel's own hands. On 25 July 1823, the world's first lighthouse Fresnel lens was lit. As expected, the light was visible to the horizon, more than 20 (mi) out.The day before the test of the Cordouan lens in Paris, a committee of the Academy of Sciences reported on Fresnel's memoir and supplements on double refraction—which, although less well known to modern readers than his earlier work on diffraction, struck a more decisive blow for the wave theory of light. Between the test and the reassembly at Cordouan, Fresnel submitted his papers on photoelasticity (16 September.

Fresnel lens. 1822), elliptical and circular polarization and optical rotation (9 December), and partial reflection and total internal reflection (7 January 1823), essentially completing his reconstruction of physical optics on the transverse wave hypothesis. Shortly after the Cordouan lens was lit, Fresnel started coughing up blood.In May 1824, Fresnel was promoted to Secretary of the , becoming the first member of that body to draw a salary, albeit in the concurrent role of Engineer-in-Chief. Late that year, being increasingly ill, he curtailed his fundamental research and resigned his seasonal job as an examiner at the , in order to save his remaining.

Fresnel lens. time and energy for his lighthouse work.In the same year he designed the first "fixed" lens—for spreading light evenly around the horizon while minimizing waste above or below. Ideally the curved refracting surfaces would be segments of toroids about a common vertical axis, so that the dioptric panel would look like a cylindrical drum. If this was supplemented by reflecting (catoptric) rings above and below the refracting (dioptric) parts, the entire apparatus would look like a beehive. The second Fresnel lens to enter service was indeed a fixed lens, of third order, installed at Dunkirk by 1 February 1825. However,.

Fresnel lens. due to the difficulty of fabricating large toroidal prisms, this apparatus had a 16-sided polygonal plan.In 1825 Fresnel extended his fixed-lens design by adding a rotating array outside the fixed array. Each panel of the rotating array was to refract part of the fixed light from a horizontal fan into a narrow beam.Also in 1825, Fresnel unveiled the ('lighthouse map'), calling for a system of 51 lighthouses plus smaller harbor lights, in a hierarchy of lens sizes called "orders" (the first being the largest), with different characteristics to facilitate recognition: a constant light (from a fixed lens), one flash per.

Fresnel lens. minute (from a rotating lens with eight panels), and two per minute (16 panels).In late 1825, to reduce the loss of light in the reflecting elements, Fresnel proposed to replace each mirror with a catadioptric prism, through which the light would travel by refraction through the first surface, then total internal reflection off the second surface, then refraction through the third surface. The result was the lighthouse lens as we now know it. In 1826 he assembled a small model for use on the , but he did not live to see a full-sized version: he died on 14 July.

Fresnel lens. 1827, at the age of 39.## After Fresnel.The first stage of the development of lighthouse lenses after the death of Augustin Fresnel consisted in the implementation of his designs. This was driven in part by his younger brother Léonor—who, like Augustin, was trained as a civil engineer but, unlike Augustin, had a strong aptitude for management. Léonor entered the service of the Lighthouse Commission in 1825, and went on to succeed Augustin as Secretary.The first fixed lens to be constructed with toroidal prisms was a first-order apparatus designed by the Scottish engineer Alan Stevenson under the guidance of Léonor Fresnel,.

Fresnel lens. and fabricated by Isaac Cookson & Co. using French glass; it entered service at the Isle of May, Scotland, on 22 September 1836. The first large catadioptric lenses were made in 1842 for the lighthouses at Gravelines and Île Vierge, France; these were fixed third-order lenses whose catadioptric rings (made in segments) were one metre in diameter. Stevenson's first-order Skerryvore lens, lit in 1844, was only partly catadioptric; it was similar to the Cordouan lens except that the lower slats were replaced by French-made catadioptric prisms, while mirrors were retained at the top. The first "fully" catadioptric first-order lens, installed.

Fresnel lens. at Pointe d'Ailly in 1852, also gave eight rotating beams plus a fixed light at the bottom; but its top section had eight catadioptric panels focusing the light about 4 degrees ahead of the main beams, in order to lengthen the flashes. The first fully catadioptric lens with "purely revolving" beams—also of first order—was installed at Saint-Clément-des-Baleines in 1854, and marked the completion of Augustin Fresnel's original "Carte des Phares".Thomas Stevenson (younger brother of Alan) went a step beyond Fresnel with his "holophotal" lens, which focused the light radiated by the lamp in nearly all directions, forward or backward, into.

Fresnel lens. a single beam. The first version, described in 1849, consisted of a standard Fresnel bull's-eye lens, a paraboloidal reflector, and a rear hemispherical reflector (functionally equivalent to the Rogers mirror of 60 years earlier, except that it subtended a whole hemisphere). Light radiated into the forward hemisphere but missing the bull's-eye lens was deflected by the paraboloid into a parallel beam surrounding the bull's-eye lens, while light radiated into the backward hemisphere was reflected back through the lamp by the spherical reflector (as in Rogers' arrangement), to be collected by the forward components. The first unit was installed at North.

Fresnel lens. Harbour, Peterhead, in August 1849. Stevenson called this version a "catadioptric holophote", although each of its elements was either purely reflective or purely refractive. In the second version of the holophote concept, the bull's-eye lens and paraboloidal reflector were replaced by a catadioptric Fresnel lens—as conceived by Fresnel, but expanded to cover the whole forward hemisphere. The third version, which Stevenson confusingly called a "dioptric holophote", was more innovative: it retained the catadioptric Fresnel lens for the front hemisphere, but replaced the rear hemispherical reflector with a hemispherical array of annular prisms, each of which used "two" total internal reflections.

Fresnel lens. to turn light diverging from the center of the hemisphere back toward the center. The result was an all-glass holophote, with no losses from metallic reflections.James Timmins Chance modified Thomas Stevenson's all-glass holophotal design by arranging the double-reflecting prisms about a vertical axis. The prototype was shown at the 1862 International Exhibition in London. Later, to ease manufacturing, Chance divided the prisms into segments, and arranged them in a cylindrical form while retaining the property of reflecting light from a single point back to that point. Reflectors of this form, paradoxically called "dioptric mirrors", proved particularly useful for returning light.

Fresnel lens. from the landward side of the lamp to the seaward side.As lighthouses proliferated, they became harder to distinguish from each other, leading to the use of colored filters, which wasted light. In 1884, John Hopkinson eliminated the need for filters by inventing the "group-flashing" lens, in which the dioptric and/or the catadioptric panels were split so as to give multiple flashes—allowing lighthouses to be identified not only by frequency of flashes, but also by multiplicity of flashes. Double-flashing lenses were installed at Tampico (Mexico) and Little Basses (Sri Lanka) in 1875, and a triple-flashing lens at Casquets Lighthouse (Channel Islands).

Fresnel lens. in 1876. The example shown (right) is the double-flashing lens of the Point Arena Light, which was in service from 1908 to 1977.The development of hyper-radial lenses was driven in part by the need for larger light sources, such as gas lights with multiple jets, which required a longer focal length for a given beam-width, hence a larger lens to collect a given fraction of the generated light. The first hyper-radial lens was built for the Stevensons in 1885 by F. Barbier & Cie of France, and tested at South Foreland Lighthouse with various light sources. Chance Brothers (Hopkinson's employers).

Fresnel lens. then began constructing hyper-radials, installing their first at Bishop Rock Lighthouse in 1887. In the same year, Barbier installed a hyper-radial at Tory Island. But only about 30 hyper-radials went into service before the development of more compact bright lamps rendered such large optics unnecessary (see "Hyperradiant Fresnel lens").Production of one-piece stepped dioptric lenses—roughly as envisaged by Buffon—became feasible in 1852, when John L. Gilliland of the Brooklyn Flint-Glass Company patented a method of making lenses from pressed and molded glass. The company made small bull's-eye lenses for use on railroads, steamboats, and docks; such lenses were common in the.

Fresnel lens. United States by the 1870s. In 1858 the company produced "a very small number of pressed flint-glass sixth-order lenses" for use in lighthouses—the first Fresnel lighthouse lenses made in America. By the 1950s, the substitution of plastic for glass made it economic to use Fresnel lenses as condensers in overhead projectors.
