The Histories · 5.43

Then Antichares a man of Eleon gave him counsel out of the oracles of Laïos to make a settlement at Heracleia in Sicily, saying that the whole land of Eryx belonged to the Heracleidai, since Heracles himself had won it: and hearing this he went forthwith to Delphi to inquire of the Oracle whether he would be able to conquer the land to which he was setting forth; and the Pythian prophetess replied to him that he would conquer it. Dorieos therefore took with him the armament which he conducted before to Libya, and voyaged along the coast of Italy.
