^"Melanion" is used by Apollodorus, 3.9.2, Pausanias, 3.12.9; "Meilanion" occurs at Xenophon (On Hunting 1.2 & 7); "Hippomenes" occurs in Theocritus, Idyll 3.40; Euripides (as noted in the Bibliotheca l. c.; Euripides' work in question hasn't survived) and in most Roman authors. Ovid in Ars Amatoria (2.188) and Propertius, Elegies 1.1.9, use Milanion, apparently the Latin spelling for "Meilanion". It may have been that Melanion, son of Amphidamas, and Hippomenes, son of Megareus, were two distinct figures appearing in the same role interchangeably.
