Which lines from book 31 of homers odyssey depict the theme of disguise

In

the book there is a part where Odysseus makes it back to his homeland

where he meets with the goddess Athene. She herself was disguised as

a young shepherd to approach him and then reveals to him her true

identity. She then disguises Odysseus to take back his home.

Athena

tells Odysseus she will disguise him as a beggar, because she is the

master of disguises and no one likes to look too closely at beggars

anyway.

“Athena

transforms him into an old man as a disguise. Clad in a filthy tunic,

he goes off to find his faithful swineherd, as instructed by the

goddess.”
