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

goddess.”</span>
