The mythical King Erichthonius /ɛrᵻkˈθoʊniəs/ of Dardania was the son of Dardanus, King of Dardania, and Batea, (although some legends say his mother was Olizone, descendant of Phineus). He is said to have enjoyed a peaceful and prosperous reign.
Fundamentally, all that is known of this Erichthonius comes from Homer, who says (Samuel Butler's translation of Iliad 20.215-234):
In the beginning Dardanos was the son of Zeus, and founded Dardania, for Ilion was not yet established on the plain for men to dwell in, and her people still abode on the spurs of many-fountained Ida. Dardanos had a son, king Erichthonios, who was wealthiest of all men living; he had three thousand mares that fed by the water-meadows, they and their foals with them. Boreas was enamored of them as they were feeding, and covered them in the semblance of a dark-maned stallion. Twelve filly foals did they conceive and bear him, and these, as they sped over the fertile plain, would go bounding on over the ripe ears of wheat and not break them; or again when they would disport themselves on the broad back of Ocean they could gallop on the crest of a breaker. Erichthonios begat Tros, king of the Trojans, and Tros had three noble sons, Ilos, Assarakos, and Ganymede who was comeliest of mortal men; wherefore the gods carried him off to be Zeus' cupbearer, for his beauty's sake, that he might dwell among the immortals.
