Eudoxus

of Cnidos, whom Cicero calls the prince of astronomers, lived about 370 8. c.; was the scholar and friend of Plato, and traveled into Egypt, where he continued for 13 years in intimate intercourse with the priests. All his works are lost, but) the poem of “Aratus” on astronomy shows the extent of his astronomical knowledge, for the commentary on this poem by Hipparch us proves it is nothing else than a metrical version of the “Phenomena” of Eudoxus, a work written in prose. Eudoxus seems to have been the first to introduce an astronomical globe into Greece, and this | may account for the pe reputation which he acquired and long continued | to enjoy.
