Respecting Philolaus, see the valuable collection of his fragments, and commentary on them, by Boeckh (Philolaus des Pythagoreers Leben, Berlin, 1819). That Philolaus was the first who composed a work on Pythagorean science, and thus made it known beyond the limits of the brotherhood—among others to Plato—appears well established (Boeckh, Philolaus, p. 22; Diogen. Laërt. viii, 15-55; Jamblichus, c. 119). Simmias and Kebês, fellow-disciples of Plato under Sokratês, had held intercourse with Philolaus at Thebes (Plato, Phædon, p. 61), perhaps about 420 B. C. The Pythagorean brotherhood had then been dispersed in various parts of Greece, though the attachment of its members to each other seems to have continued long afterwards.
