How does Athena alter Odysseus' appearance before he reaveals himself to telemachus?

Before Odysseus reveals himself to Telemachus, Athena alters his appearance to make him look more youthful and handsome. She transforms his ragged features, restoring his strength and vitality, so he can appear as the noble and heroic figure he once was. This change not only helps him gain Telemachus's trust but also emphasizes the divine support Odysseus receives from Athena in reclaiming his identity and place in his household.
