17. Of TYRE, a Peripatetic philosopher, a disciple and follower of Critolaus, whom he succeeded as the head of the Peripatetic school at Athens. He was still alive and active there in B. C. 110, when L. Crassus, during his quaestorship of Macedonia, visited Athens. Cicero denies to him the character of a genuine Peripatetic, because it was one of his ethical maxims, that the greatest good consisted in a combination of virtue with the absence of pain, whereby a reconciliation between the Stoics and Epicureans was attempted. (Cic. de Orat. 1.11, Tusc. 5.30, de Fin. 2.6, 11, 4.18, 5.5, 8, 25, Acad. 2.42; Clem. Al. Strom. i. p. 301, ii. p. 415.)

There are some more persons of the name of Diodorus, concerning whom nothing of interest is known. See the list of them in Fabric. Bibl. Gr. iv. p. 378, &c.
