But the goddess drifted through like a breath of fresh air,
rushed to the girl’s bed and hovering close she spoke,
in face and form like the shipman Dymas’ daughter,
a girl the princess’ age, and dearest to her heart.

– Homer

The Odyssey, Book 6, lines 23-26. Athena appears in a dream to the Phaeacian king’s daughter Nausicaa. The goddess, a master of disguises, takes the form of Nausicaa’s friend so that the princess will take heed of what Athena tells her.
