a Greek philosopher, born at Erythreum, was the son of Calithenes, and one of Phedo's followers. He was in the greatest esteem, and enjoyed several important posts, in his own country. He several times defended Erythreum with great bravery, and died of grief when Antigonus became master of it. A person one day saying to him, "It is a great happiness to have what we desire," he replied, "It is a much greater to desire nothing but what we have." He flourished about 300 B. C.
