TMTh:: OENOPIDES OF CHIOS MATHEMATICIAN, ASTRONOMER oenopides of chios (fl. 5th century BC) LifeCited by Diodorus Siculus and by Proclus in his Commentary http://www.tmth.edu.gr/en/aet/2/73.html
Extractions: Cited by Diodorus Siculus and by Proclus in his "Commentary on Euclid", Oenopides travelled widely through Egypt and acquired considerable skill in astronomy. His work focused on studies of the lunar and solar years. The discoveries he made were engraved on a bronze tablet which he offered to Olympia. The introduction into Greece the "Great Year" of 59 years. Oenopides accepted a year of 365 days and a month of 291/2 days. 59 is the largest whole number of years that contains an exact number of lunar months (730). Since 730 lunar months correspond to 21,557 days, each year in the Great Year would have 365.373 days, or a little less than 365 days and 9 hours.

Extractions: Very little is known about the life of Oenopides of Chios except that his place of birth was the island of Chios. We believe that Oenopides was in Athens when a young man but there is only circumstantial evidence for this. In Plato 's Erastae Oenopides is described as (see for example [1]):- ... having acquired a reputation for mathematics... and Plato also describes a scene where Socrates comes across two young men in the school of Dionysius who was Plato 's teacher. The young men were discussing a question in mathematical astronomy which had been tackled by Oenopides and Anaxagoras . This question was certainly that of the angle that the ecliptic makes with the celestial equator . Bulmer-Thomas writes in [1]:- ... it was probably Oenopides who settled on the value of , which was accepted in Greece until refined by Eratosthenes . Indeed, if Oenopides did not fix on this or some other figure it is difficult to know in what his achievement consisted, for the Babylonians no less than the Pythagoreans and Egyptians must have realised from early days that the apparent path of the sun was inclined to the celestial equator.

Extractions: Math 105 History of Mathematics, D Joyce. Spring, 1999 Source: Thomas Heath, Aristarchus of Samos, the Ancient Copernicus, Clarendon Press, Oxford, 1913. Reprinted by Dover, New York, 1981. Thales of Miletus (c. 630? - c 550? BC) Statesman, engineer, mathematician and astronomer, one of the "seven wise men." Cosmology: earth floated on water, a disk. Sun, stars, and planets fiery. Perhaps based on Egyptian and/or Babylonian cosmology. Said to have predicted a solar eclipse, but unlikely. Eudemus referred to two written works by Thales: On the Solstice and On the Equinox, since lost. Noted length of four seasons not all the same. Diogenes Laertius says Thales declared the apparent size of the sun and the moon to be 1/720 part of the circle described by it (i.e., 1/2 degree). Recommended sailing by Little Bear (Little Dipper) as the Phoenicians did. Anaximander of Miletus (Anasimandros) (c. 611 - c. 547 BC) Considered first Greek philosopher. Student of Thales. Cosmology: earth at center, a disk with depth 1/3 of breadth floating in air. Believed the stars to be fiery wheels emitting flames through vents, and eclipses occur when the vents are stopped up. Concluded the circle of the sun is 27 or 28 times the size of the earth, and that of the moon 18 or 19 times. Probably brought the vertical sundial (gnomon) to Greeks from Babylonians. Said to be first to draw a map of the inhabited earth. Anaximenes of Miletus (c. 585 - c. 528 BC. Stars on crystal sphere, but planets have their own movements. Sun, moon, stars made of fire. Said eclipses due to obscuring dark bodies.

Diodorus On The Greek Cultural Debt and the philosopher Plato, and that there came also Pythagoras of Samos and the mathematicianEudoxus, as well as Democritus of Abdera and oenopides of chios. http://academic.reed.edu/humanities/110Tech/Diodorus1.96-98.html
Extractions: Diodorus on the Greek Cultural Debt to Egypt (based on Oldfather's tr.) But now that we have examined these matters we must enumerate what Greeks, who have won fame for their wisdom and learning, visited Egypt in ancient times in order to become acquainted with its customs and learning. For the priests of Egypt recount from the records of their sacred books that they were visited in early times by Orpheus, Musaeus, Melampus, and Daedalus, also by the poet Homer and Lycurgus of Sparta, later by Solon of Athens and the philosopher Plato, and that there came also Pythagoras of Samos and the mathematician Eudoxus, as well as Democritus of Abdera and Oenopides of Chios. As evidence for the visits of all these men they point in some cases to their statues and in others to places or buildings which bear their names, and they offer proofs from the branch of learning which each one of these men pursued, arguing that all the things for which they were admired among the Greeks were borrowed from Egypt. (1.96) And as proof of the presence of Homer they adduce various pieces of evidence , and especially the healing drink which brings forgetfulness of all past evils, which was given by Helen to Telemachus in the home of Menelaus [in Book Four of the Odyssey] ... for, they allege, even to this day the women of this city [Thebes in Egypt] use this powerful remedy. (1.97)
