Acestes

In Roman mythology, Acestes or Egestes (Greek Ἄκέστης) was the son of the Sicilian river-god Crinisus by a Dardanian or Trojan woman named Egesta or Segesta.

According to Servius, this woman Egesta or Segesta was sent by her father, Hippotes or Ipsostratus, to Sicily, that she might not be devoured by the monsters, which infested the territory of Troy, and which had been sent into the land, because the Trojans had refused to reward Poseidon and Apollo for having built the walls of their city. When Egesta arrived in Sicily, the river-god Crinisus in the form of a bear or a dog sired with her a son named Acestes, who was afterwards regarded as the hero who had founded the town of Segesta.
