Laomedon's possible wives were Placia, Strymo (or Rhoeo), Zeuxippe[9] or Leucippe;[3][10] by the former he begot Tithonus and by the latter King Priam («ὁ μὲν γὰρ Πρίαμος ἦν Λευκίππης, ὁ δὲ Τιθωνὸς Ῥοιοῦς ἢ Στρυμοῦς τῆς Σκαμάνδρου θυγατρὸς υἱός»: "Priamus was the son of Leucippe, whereas Tithonus was the son of Rhoeo or Strymo, the daughter of Scamander".

According to one story, Ganymede was kidnapped by Zeus, who had seen the exceptional Virtue of the boy, as worthy only of Olympus, and ascended the young man into Heaven.

When Poseidon and Apollo entered a conspiracy to put Zeus in bonds, the supreme god being offended, sent them to serve with King Laomedon as punishment for their nefarious design.

[17] As ordered by Laomedon who promised wages, the two deities assuming the likeness of men undertook to build huge walls around the city.

In vengeance, before the Trojan War, Apollo sent a pestilence to Troy while Poseidon released a sea monster which, carried up by a flood, snatched away the people of the plain.

The hero promised to save the princess on condition of receiving from Laomedon the mares which Zeus had given in compensation for the ascendance of Ganymede into Olympus to serve the Deities.

But when Laomedon would not give up his magical horses for their deeds, the hero put to sea after threatening to make war on Troy.After his servitude, Heracles mustered an army of noble volunteers and sailed for Ilium with eighteen ships of fifty oars each.

So, when the prince was being sold, Hesione took the golden veil from her head and gave it as a ransom; hence Podarces was thereafter called Priam (from priamai 'to buy').
