Telegonus was a demigod and the youngest son of Circe and Odysseus.
Telegonus was the son of the sorceress Circe and Odysseus, the king of Ithaca. When Telegonus grew up, Circe sent him to find Odysseus, who by this time had finally returned to Ithaca from the Trojan War. On his arrival Telegonus began plundering the island, thinking it was Corcyra (Corfu). Odysseus and his oldest son, Telemachus, defended their city and Telegonus accidentally killed his father with the spine of a stingray. He brought the body back to Aeaea and took Penelope, Odysseus' widow, and Telemachus, Odysseus' son, with him. Circe made them immortal and married Telemachus, while Telegonus made Penelope his wife. With Penelope, he was the father of Italus.
