Claude Duret points out that the Hebrews, the Canaans, the Samaritans, the Chaldeans, the Syrians, the Egyptians, the Carthaginians, the Phoenicians, the Arabs, the Saracens, the Turks, the Moors, the Persians, and the Tartars all write from right to left, following 'the course and daily movement of the first heaven, which is most perfect, according to the opinion of the great Aristotle, tending towards unity'; the Greeks, the Georgians, the Maronites, the Serbians, the Jacobites, the Copts, the Poznanians, and of course the Romans and all Europeans write from left to right, following 'the course and movement of the second heaven, home of the seven planets'; the Indians, Cathayans, Chinese, and Japanese write from top to bottom, in conformity with the 'order of nature, which has given men heads at the tops of their bodies and feet at the bottom'; 'in opposition to the aforementioned', the Mexicans write either from bottom to top or else in 'spiral lines, such as those made by the sun in its annual journey through the Zodiac'.
