(Δίυλλος), an Athenian, who wrote a history of Greece and Sicily in 26 or 27 books. It was divided apparently into several parts, the first of which extended from the seizure of the Delphic temple by Philomelus (where the history of Callisthenes ended) to the siege of Perinthus, by Philip (B. C. 357-340), and the second from B. C. 340 to 336, the date of Philip's death. The work was carried on, according to Diodorus, down to B. C. 298, from which period Psaon, of Plataea, continued it. If we accede to Casaubon's substitution of Δίυλλος for Δίδυμος, in D. L. 5.76, we must reckon also a work on drinking-parties (συμποσιακά) among the writings of Diyllus. The exact period at which he flourished cannot be ascertained, but he belongs to the age of the Ptolemies. (Diod. 16.14, 76, xxi., Fragm. 5, p. 490; Plut. de Herod. Mal. 26; Ath. iv. p. 155a, xiii. p. 593f; Maussac. ad Harpocrat. s. v. Ἀριστίων; Wesseling, ad Diod. 16.14; Clinton, F. H. vol. ii. sub ann. 357, 339, 298, p. 377.)
