Another source mentions that Circe and Odysseus had three sons; Ardeas, Latinus, and Telegonus. In a lost epic called Telegony, Circe told Telegonus that his father was Odysseus (who had meanwhile returned to Ithaca and his wife, Penelope), and Telegonus went to find him. However, Circe gave him a poisoned spear, with which Telegonus mistakenly killed his father. Afterwards, he returned home along with Penelope and Telemachus, his half brother, and Circe granted them immortality.
