Note 60 — Chapter III · HISTORY OF THE STOICS UNTIL THE END OF THE SECOND CENTURY B.C.

According to Diog. vi. 81; Lucian, Macrob. 20, he was a native of Seleucia on the Tigris; but he is sometimes called a native of Babylon (Diog. vii. 39; 55; Cic. N. D. i. 15, 41; Divin. i. 3, 6; Plut. De Exil. 14, p. 605). Cic. Divin. i. 3, 6, calls him a pupil of Chrysippus; and Acad. ii. 30, 98, the instructor of Carneades in dialectic. Plut. Alex. Virt. 5, p. 328, calls him a pupil of Zeno (of Tarsus). Zeno, he says, Διογένη τὸν Βαβυλώνιον ἔπεισε φιλοσοφεῖν. Diog. vii. 71, mentions a διαλεκτικὴ τέχνη of his; and, vii. 55 and 57, a τέχνη περὶ φωνῆς. Cic. Divin. i. 3, 6, speaks of a treatise on divination. Athen. iv. 168, e, of a treatise περὶ εὐγενείας, xii. 526. d, of a work περὶ νόμων—the same work probably which, according to Cic. Legg. iii. 5, 14, was written ‘a Dione Stoico.’ Cic. Off. iii. 12, 51, calls him ‘magnus et gravis Stoicus;’ Seneca, De Ira, iii. 38, 1, mentions a trait showing great presence of mind. Diogenes was, without doubt, aged in 156 B.C. (Cic. De Senec. 7, 23). According to Lucian, he attained the age of 88, and may therefore have died 150 B.C. ↑
