"First I will transform you – no one must know you.
I will shrivel the supple skin on your lithe limbs,
strip the russet curls from your head and deck you out
in rags you’d hate to see some other mortal wear;
I’ll dim the fire in your eyes, so shining once –
until you seem appalling to all those suitors,
even your wife and son you left behind at home."

– Homer

The Odyssey, Book 13, lines 454-460. Athena prepares Odysseus for his return incognito to his palace at Ithaca. She transforms him into an old man. This is so that he will be safe entering his house, fool the suitors and not worry about them putting him to death.
