He recruits a crew from the simple folk of Iolcus, including shepherds and farmers. He is joined by Hercules, Orpheus, Atalanta and the brothers Castor and Pollux. Acastus stows away on the ship. The Argonauts run aground on a strange island in the middle of the ocean that is actually the sea god Poseidon. In the ensuing storm, they lose the map. The crew make their way to the Isle of Lemnos, an island of warrior women, to recover from the experience and repair the ship. The men pleasure themselves with the women while their ship is repaired (except Orpheus and Atalanta) and Jason sleeps with the queen Hypsipyle. Atalanta discovers that the women have killed all the men on the island and are planning to sacrifice the crew. She warns Jason, and the Argonauts flee the island.
