A Greek philosopher; born at Citium, a Greek colony on the island of Cyprus, about 350 B. C.; died, as is reported, by his own hand, about 264 B. C. He was the son of a merchant, and followed his father's profession, not visiting Athens till his thirtieth year. He then read Xenophon and Plato, and later founded a school of his own. None of his writings have been preserved, but he is known to have combined the ethics of the Cynic school with the physics of Pythagoras and Heraclitus.
