I. Since we have now gone through the Ionian philosophy, which was derived from Thales, and the lives of the several illustrious men who were the chief ornaments of that school; we will now proceed to treat of the Italian School, which was founded by Pythagoras, the son of Mnesarchus, a seal engraver, as he is recorded to have been by Hermippus; a native of Samos, or as Aristoxenus asserts, a Tyrrhenian, and a native of one of the islands which the Athenians occupied after they had driven out the Tyrrhenians. But some authors say that he was the son of Marmacus, the son of Hippasus, the son of Euthyphron, the son of Cleonymus, who was an exile from Phlias; and that Marmacus settled in Samos, and that from this circumstance Pythagoras was called a Samian. After that he migrated to Lesbos, having come to Pherecydes with letters of recommendation from Zoilus, his uncle. And having made three silver goblets, he carried them to Egypt as a present for each of the three priests. He had brothers, the eldest of whom was named Eunomus, the middle one Tyrrhenus, and a slave named Zamolxis, to whom the Getæ sacrifice, believing him to be the same as Saturn, according to the account of Herodotus.[107] II. He was a pupil, as I have already mentioned, of Pherecydes, the Syrian; and after his death he came to Samos, and became a pupil of Hermodamas, the descendant of Creophylus, who was by this time an old man. III. And as he was a young man, and devoted to learning, he quitted his country, and got initiated into all the Grecian and barbarian sacred mysteries. Accordingly, he went to Egypt, on which occasion Polycrates gave him a letter of introduction to Amasis; and he learnt the Egyptian language, as Antipho tells us, in his treatise on those men who have been conspicuous for virtue, and he associated with the Chaldæans and with the Magi. Afterwards he went to Crete, and in company with Epimenides, he descended into the Idæan cave, (and in Egypt too, he entered into the holiest parts of their temples,) and learned all the most secret mysteries that relate to their Gods. Then he returned back again to Samos, and finding his country reduced under the absolute dominion of Polycrates, he set sail, and fled to Crotona in Italy. And there, having given laws to the Italians, he gained a very high reputation, together with his scholars, who were about three hundred in number, and governed the republic in a most excellent manner; so that the constitution was very nearly an aristocracy.
