(Ἑκάτων), a Stoic philosopher, a native of Rhodes. All that we know of his personal history is contained in a passage of Cicero (de Off. 3.15); but besides the name of his birth-place we learn nothing more from it than that he studied under Panaetius. He seems also to have been closely connected with the principal Stoic philosophers of his age. Of his somewhat voluminous writings nothing now remains. He was the author of the following treatises :--De Officiis (Cic. de Off. 3.15, 23); Περὶ ἀγαθῶν, in at least nineteen books; Περι ἀρετῶν; Περὶ παθῶν; Περὶ τελῶν; Περὶ παραδόξων, in at least thirteen books ; Χπεῖαι (D. L. 7.103, 101, 127, 125, 90, 110, 87, 102, 124, 26, 172, 6.4, 32, 95.) Hecaton is also frequently mentioned by Seneca in his treatise De Beneficiis. (Fabric. Bibl. Graec. vol. 3.563.)
