1. Of Chios, a Pythagorean philosopher, who lived about S. C. 460.
He is mentioned chiefly as a mathematician, and is said to have been the first who reduced
geometry to a regular system. He seems to have been also engaged in researches respecting the
square of a circle; but we have no means of judging of his merits as a mathematician, and
Aristotle (Ethic. ad Eudem. 8.14) states that in every other respect he
was a man not above mediocrity. (Comp. Aristot. Sophist. Elench. 1.10;
in Euclid. ii. p.
19; Fabric. Bibl. Graec. vol. i. p. 848, &c.)
