Note 260 — Chapter II · SCIENCE AND RELIGION
Reading edition
This is quoted by Plutarch, de def. orac. 422 b, d, from Phanias of Eresos, who gave it on the authority of Hippys of Rhegion. If we may follow Wilamowitz (Hermes, xix. p. 444) in supposing that this really means Hippasos of Metapontion (and it was in Rhegion that the Pythagoreans took refuge), this is a very valuable piece of evidence.
