Diocles
5. Of PEPARETHUS, the earliest Greek historian, who wrote about the foundation of Rome, and whom Q. Fabius Pictor is said to have followed in a great many points. (Plut. Rom. 3, 8; Fest. s. v. Romam.) How long he lived before the time of Fabius Pictor, is unknown. Whether he is the same as the author of a work on heroes (περὶ ἡρώων σύνταγμα), which is mentioned by Plutarch (Quaest. Graec. 40), and of a history of Persia (Περσικά), which is quoted by Josephus (Ant. Jud. 10.11.1), is likewise uncertain, and it may be that the last two works belong to Diocles of Rhodes, whose work on Aetolia (Αἰτωλικά) is referred to by Plutarch. (De Flum. 22.)
