Quoted from epsilon 337.
Dymas (genitive Dymantos), father of Hecuba (epsilon 337) and the Asios in whose form Apollo appears in order to urge Hector (Homer, Iliad 16.717), occurs in a genealogy of Phrygian kings and nobles known to Homer, who may draw his knowledge of ancient Troy from some contact with the Phrygia of the great King Midas, contemporary (he died in the Cimmerian raid of 696) with the probable dates of the author of the Iliad and Odyssey, and married to a daughter of a real King Agamemnon of Cyme, the Greek city with the best claim to Homer's childhood. The Lives of Homer, which may contain some grains of biographical truth (see omicron 251, notes), say that he wrote an epitaph for Midas (see mu 1036, although certainly not the one they quote, unless it is a translation from Phrygian).
It is also interesting to note that Athena appears in the Odyssey in the form of a child of "sea-going" Dymas, to Nausicaa. Certain possible parallels with the fictitious Phaeacians (both peoples lost their mastery of the sea) suggest that Homer may draw for his portrait in Odyssey 6 from the Phrygians.
This Dymas (Dymant-) is to be distinguished from the eponymous ancestor of the Dorian tribe Dymanes (Ephorus, Stephanus of Byzantium), Dymainai or (in Sparta) Dymanis (scholia on Pindar, Pythian 1.121) or Dymanatai (Herodotus 5.68.13), a certain Dymas (stem Dyman-; erroneously Dymant- at Pausanias 7.17.6. and Lycophron, Alexandra 1388), son of Aigimios (Stephanus of Byzantium, s.v. Dymanes (240.12), quoting Ephorus; Hesiod fr.10(a).7; Alcman fr.19.8).
