Book 8
1.41
Hermippus gives another anecdote. Pythagoras, on coming to Italy, made a subterranean dwelling and enjoined on his mother to mark and record all that passed, and at what hour, and to send her notes down to him until he should ascend. She did so. Pythagoras some time afterwards came up withered and looking like a skeleton, then went into the assembly and declared he had been down to Hades, and even read out his experiences to them. They were so affected that they wept and wailed and looked upon him as divine, going so far as to send their wives to him in hopes that they would learn some of his doctrines; and so they were called Pythagorean women. Thus far Hermippus.
1.42
Pythagoras had a wife, Theano by name, daughter of Brontinus of Croton, though some call her Brontinus’s wife and Pythagoras’s pupil. He had a daughter Damo, according to the letter of Lysis to Hippasus, which says of him, I am told by many that you discourse publicly, a thing which Pythagoras deemed unworthy, for certain it is that, when he entrusted his daughter Damo with the custody of his memoirs, he solemnly charged her never to give them to anyone outside his house. And, although she could have sold the writings for a large sum of money, she would not, but reckoned poverty and her father’s solemn injunctions more precious than gold, for all that she was a woman.
