But Athena had approached Laertes’ son Odysseus,
tapped him with her wand and made him old again.
She dressed him in filthy rags too, for fear Eumaeus,
recognizing his master face-to-face, might hurry
back to shrewd Penelope, blurting out the news
and never hide the secret in his heart.

– Homer

The Odyssey, Book 16, lines 505-510. Athena taps Odysseus with her wand and turns him into the old beggar again, so that Eumaeus won’t recognize him on his return to the farm.
