He returned with his mind well stored and his judgment matured, to his home, intending to open there a College of learning, but this he found to be impracticable owing to the opposition of its turbulent ruler Polycrates. Failing in this design, he migrated to Crotona, a noted city in Magna Graecia, which was a colony founded by Dorians on the South coast of Italy. It was here that this ever-famous Philosopher founded his College or Society of Students, which became known all over the civilized world as the central assembly of the learned of Europe; and here it was in secret conclave that Pythagoras taught that occult wisdom which he had gathered from the Gymnosophists and Brahmins of India, from the Hierophants of Egypt, the Oracle of Delphi, the Idaean cave, and from the Kabalah of the Hebrew Rabbis and Chaldean Magi. For nearly forty years he taught his pupils, and exhibited his wonderful powers; but an end was put to his institution, and he himself was forced to flee from the city, owing to a conspiracy and rebellion which arose on account of a quarrel between the people of Crotona and the inhabitants of Sybaris: he succeeded in reaching Metapontum, where he is said to have died about the year 500 B.C.
