In the Odyssey, she was the first person to recognize him after he returned home from the Trojan War, after he entered his own house as a guest of Penelope, disguised as a beggar. Euryclea bathed him and recognized him by a scar on his leg, which he had received from a boar while hunting with his grandfather Autolycus. Odysseus stopped her from telling Penelope or anyone else of his true identity.
Euryclea also informed Odysseus which of his servant girls had been unfaithful to Penelope during his absence, conspiring with Penelope's suitors and becoming their lovers. He hanged the twelve that Euryclea identified.
Later Euryclea helps Penelope confirm that Odysseus has indeed returned. Penelope tells her to move the bed Odysseus built in their marriage-chamber; Odysseus recognizes that it has been moved, and Penelope finally accepts him.
In other traditions Euryclea was also known as Antiphata.
Euryclea bathed him and recognized him by a scar on his leg, which he had received from a boar while hunting with his grandfather Autolycus.
Penelope tells her to move the bed Odysseus built in their marriage-chamber; Odysseus tells Penelope that this is not possible as one of the legs of the bed is built into a live olive tree, a secret that only Odysseus and Penelope know, and Penelope finally accepts him.
Odysseus was the king of Ithaca, husband of Penelope and father of Telemachus, favorite of Athena, and wiliest of the Greeks involved in the Trojan War.
Odysseus saw that Penelope was faithful to him, pretending to knit a burial shroud (for they claimed he must be dead) and claiming she would choose one suitor when she finished.
