Sosigenes the Peripatetic
- Sosigenes the Peripatetic
Sosigenes the Peripatetic was a philosopher living at the end of the 2nd century AD. He was the tutor of Alexander of Aphrodisias and wrote a work "On Revolving Spheres", from which some important extracts have been preserved in Simplicius's commentary on Aristotle's "De Caelo".
He criticized both Aristotle and Eudoxus, and their theory of celestial spheres and epicycles, which he felt was inconsistent with Aristotle's philosophical postulates. He also pointed out that the planets varied markedly in brightness, and that eclipses of the sun are sometimes total and sometimes annular suggesting that the distances between the sun, moon and earth was not the same at different eclipses.
Sosigenes is perhaps called "the Peripatetic" only because of his connection with Alexander. Some ancient evidence may be taken to suggest that he was, in fact, a Stoic. As John Patrick Lynch has written:
The other two teachers of Alexander may actually have been the philosophers whom ancient sources called Stoics; in both cases, Herminos/Sosigenes "the Stoic" have been distinguished from Herminos/Sosigenes "the Peripatetic" only on the grounds that the two latter men were teachers of Alexander of Aphrodisias. But it is not improbable that Alexander of Aphrodisias studied with two Stoic teachers and that these two pairs of homonymous contemporaries are actually only two Stoic philosophers. [John Patrick Lynch, "Aristotle's School: A Study of a Greek Educational Institution", Berkeley: University of California Press, 1972, p. 215.]
He is often confused with the Roman astronomer Sosigenes of Alexandria.
