It is likewise related of Clinias the Tarentine, that when he had learnt that Prorus the Cyrenæan, who was zealously addicted to the Pythagorean doctrines, was in danger of losing all his property, he sailed to Cyrene, after having collected a sum of money, and restored the affairs of Prorus to a better condition, not only incurring, in so doing, a diminution of his own property, but despising the peril which he was exposed to in the voyage.
