Hecaton (gr. Hekaton) a Stoic philosopher, a native of Rhodes. All that we know of his personal history is contained in a passage of Cicero (de Off. iii. 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. iii. 15, 23); Peri agathon, in at least nineteen books; Peri areton; Peri pathon; Peri telon; Peri paradoxon, in at least thirteen books ; Chreiai (Diog. Laërt. vii. 103, 101, 127, 125, 90, 110, 87, 102, 124, 26, 172, vi. 4, 32, 95.) Hecaton is also frequently mentioned by Seneca in his treatise De Beneficiis. (Fabric. Bibl. Graec. vol. iii. 563.)
