Athena begs her father Zeus to allow her to aid Odysseus, so he can go home to his family. She says,"My own heart is broken for Odysseus". Athena goes as far as enhancing his appearance so that Princess Nausikaa will be sure to help him reach home. Once Odysseus reaches the city that Nausikaa leads him to, Athena "pours a sea fog" around him to protect him, and she takes on the form of a small girl in order to show him the way to the palace. Once Athena leads Odysseus home to Ithaka, she disguises herself as a sheperd boy and makes conversation with her beloved Odysseus. However, she eventually transforms herself into her natural state.
