Lysis

Lysis of Tarentum was a Pythagorean philosopher of the late 5th and early 4th century BCE. He is said to have been among the Pythagoreans who survived the persecutions and burning of their meeting houses in southern Italy, after which he fled to mainland Greece and settled at Thebes. There he is reported to have been a teacher of the Theban general Epaminondas. A famous letter to Hipparchus warning against divulging Pythagorean teachings circulated under his name, but it is generally regarded by scholars as a later forgery. Few firm details of his life survive.
