Alcathous of Elis Aetolia, and when his brother Callipolis hastened to carry the sad tidings to his father, he found him engaged in offering a sacrifice to Apollo, and thinking it unfit to offer sacrifices at such a moment, he snatched away the wood from the altar. Alcathous imagining this to be an act of deliberate sacrilege, killed his son on the spot with a piece of wood. The acropolis of Megara was called by a name derived from that of Alcathous. Alcathous was grandfather of the hero Ajax, via his daughter Periboea, who married Telamon, and of Iolaus, nephew and charioteer of
Telamon for Zeus' kidnapping Tros' son, Ganymede. Tros agreed; Heracles succeeded and Telamon married Hesione, Tros' daughter, by whom he sired Teucer. In the King Laomedon version, Laomedon planned on sacrificing his daughter Hesione to Poseidon in the hope of appeasing him. Heracles rescued her at the last minute and killed both the monster and Laomedon and Laomedon's sons, except for Ganymede, who was on Mount Olympus, and Podarces, who saved his own life by giving Heracles a golden veil Hesione had made. Telamon took Hesione as a war prize and married her, and she gave birth to Teucer by him.
