Proper name: DIO'GENES OENO'MAUS, a tragic poet, who is said to have begun to exhibit at Athens in B. C. 404. Of his tragedies only a few titles remain, namely, ©uc'o-ttjs, 'Ax'AAeus, 'EAevtj, 'HpaKr)s, MrjSeia, OlSivovs, Xpvaiinros, 2€/xej; and it is remarkable that all of these, except the last, are ascribed by Diogenes Laertius to Diogenes the Cynic, (vi. 80, or 73.) Others ascribe them to Philiscus of Aegina, a friend of Diogenes the Cjmic (Menagius, ad Diog. Laërt. Z. c), and others to Pasiphaon. Melanthius in Plutarch ((de Aud. Poet. 4, p. 41, d.) complains of the obscurity of a certain Diogenes. Aelian /(V. H. iii. 30, N. A. vi. 1) mentions a tragic poet Diogenes, who seems, however, to be a different person from either Diogenes the Cynic or Diogenes Oenomaiis. (Suid. s. v.; Ath. xiv. p. 636, a.; Fabric. Bilb. Graec. ii. p. 295.) [P. S.] (Wikisource | public domain)
