(Διογένης ὁ Ἀπολλωνιάτης), an eminent natural philosopher, who lived in the fifth century B. C. He was a native of Apollonia in Crete, his father's name was Apollothemis, and he was a pupil of Anaximenes. Nothing is known of the events of his life, except that he was once at Athens, and there got into trouble from some unknown cause, which is conjectured to have been the supposition that his philosophical opinions were dangerous to the religion of the state. (D. L. 9.57.)
