Parmenides, a native of Elea, son of Pyres, was a pupil of Xenophanes (Theophrastus in his Epitome makes him a pupil of Anaximander).[*](Diels considers this sentence to be a marginal note of an editor referring to Xenophanes, not Parmenides.) Parmenides, however, though he was instructed by Xenophanes, was no follower of his. According to Sotion[*](Sotion would thus appear to separate Parmenides from Xenophanes. Compare note a on p. 426. Diels conjectures that an epitaph on the Pythagoreans mentioned is the ultimate authority here.) he also associated with Ameinias the Pythagorean, who was the son of Diochaetas and a worthy gentleman though poor. This Ameinias he was more inclined to follow,
and on his death he built a shrine to him, being himself of illustrious birth and possessed of great wealth; moreover it was Ameinias and not Xenophanes who led him to adopt the peaceful life of a student.
He was the first to declare that the earth is spherical and is situated in the centre of the universe. He held that there were two elements, fire and earth, and that the former discharged the function of a craftsman, the latter of his material.
