5. Of Athens, the author of a biographical work, from which Diogenes Laertius (3.5, 4.3, 5.1, 7.1) quotes statements respecting Plato, Spensippus, Aristotle, and Zeno. Nothing is known of his age, unless these references be supposed to furnish any guide to it. Vossius is probably right in supposing him to be a different person from the Timotheus whose ʼἈργολικά and the eleventh book of whose work on Rivers are quoted by Plutarch (de Fluv. 18. 3), and also different from the writer to whom Eustathius (ad Dion. Perieg. 421) refers. (Vossius, de Hist. Graec. p. 507, ed. Westermann.)
