The earliest astrology can trace its roots to 19th Century BC. Beginning in Mesopotamia, it later spread to Greece and Rome, and eventually Central and Northern Europe.
Western astrology has twelve signs, reflecting the month in which you were born. In English, these signs are named after the original Greek words. But not the Swedish names. Like much else in the Swedish language, the words for these signs are very literal. They are also in the definite form.
