Career
In his practice, Cleinias was a true Pythagorean. Thus we hear that he used to assuage his anger by playing on his harp. And, when Prorus of Cyrene had lost all his fortune through a political revolution, Cleinias, who knew nothing of him except that he was a Pythagorean, took on himself the risk of a voyage to Cyrene, and supplied him with money to the full extent of his loss.
A text written by Cleinias exists among some other Pythagorean philosophers" at the end of Iamblichus" "Life of Pythagoras" in the referenced edition, where his name is spelled "Clinias".
