The whole idea was a phase of totemism and tabu.
That it flourished for about thirty years is very certain. Two sons and a daughter of Pythagoras grew to maturity in the college, and this daughter was tried by the Order on the criminal charge of selling the secret doctrines of her father to outsiders.
One of the sons it seems made trouble, also, in an attempt to usurp his father's place and take charge of affairs, as "next friend." One generation is about the limit of a Utopian Community. When those who have organized the community weaken and one by one pass away, and the young assume authority, the old ideas of austerity are forgotten and dissipation and disintegration enter. So do we move in circles.
The final blow to the Pythagorean College came through jealousy and misunderstanding of the citizens outside. It was the old question of Town versus Gown. The Pythagoreans numbered nearly three hundred people. They held themselves aloof, and no doubt had an exasperating pride. No strangers were ever allowed inside the walls—they were a law unto themselves.
Internal strife and tales told by dissenters excited the curiosity, and then the prejudice, of the townspeople.
Then the report got abroad that the Pythagoreans were collecting arms and were about to overthrow the local government and enslave the officials.
On a certain night, led by a band of drunken soldiers, a mob made an assault upon the college. The buildings were fired, and the members were either destroyed in the flames or killed as they rushed forth to escape. Tradition has it that Pythagoras was later seen by a shepherd on the mountains, but the probabilities are that he perished with his people. But you can not dispose of a great man by killing him. Here we are reading, writing and talking yet of Pythagoras.
