Euenus (or Evenus) of Paros, (Greek: Εὔηνος ὁ Πάριος), was a 5th-century BC philosopher and poet who was roughly contemporary with Socrates. Euenus is mentioned several times in Plato's Phaedo, Phaedrus, and Apology of Socrates. He is quoted in Aristotle's Nicomachean Ethics (7.10.1152a32) and Eudemian Ethics (2.7.1223a30). He was apparently, although obscure, well respected, and was never called a Sophist by Socrates, even though he charged a sizeable sum for teaching students.
Ten short poetic fragments of Euenus' poetry survive, mostly elegies. One pentameter cited by Aristotle also appears in the Theognidea (v. 472), which is part of a bigger poem (vv. 467-496). This poem is addressed to a Simonides, just as two other poems in the Theognidea: vv. 667-682 & vv. 1341-1350. On this ground, scholars attribute these three poems to Euenus.
Eleven poems in the Palatine Anthology are attributed to "Euenos", of which Anth. Pal. XI. 49 is most probably by Euenus. The others are probably by Euenus of Ascalon, and some may be by Euenus of Athens, Euenus of Sicily or Euenus Grammaticus. Most are about works of art.
