Poseidon's Relatives

But when Laomedon would not give the stipulated reward, Hercules put to sea after threatening to make war on Troy.

And he touched at Aenus, where he was entertained by Poltys. And as he was sailing away he shot and killed on the Aenian beach a lewd fellow, Sarpedon, son of Poseidon and brother of Poltys. And having come to Thasos and subjugated the Thracians who dwelt in the island, he gave it to the sons of Androgeus to dwell in. From Thasos he proceeded to Torone, and there, being challenged to wrestle by Polygonus and Telegonus, sons of Proteus, son of Poseidon, he killed them in the wrestling match. And having brought the belt to Mycenae he gave it to Eurystheus.
