3. There were three authors of the name of Deinarchus, concerning whom we know little beyond what is stated by Demetrius of Magnesia (Dionys. Deinarch. 1), viz. that one was a poet of Delos, who lived previous to the time of the orator, and wrote poems on Bacchic subjects (comp. Euseb. Chron. DCCXX.; Cyrill.c. Julian. x. p. 341); the second, a Cretan, made a collection of Cretan legends; and the third wrote a work upon Homer. Whether any of these is the same as the one who, according to Nemesius (de Natur. Hom. 4), taught, with Aristoxenus, that the humnan soul was nothing but a harmony, is uncertain.
