Who is Nausicaa? What does Athena tell Nausicaa she must do? Why do you think Athena does this?

Nausicaa is the daughter of King Alcinous At night, Athena visits the Phaiakian princess, Nausikaa, in a dream and urges her to wash her clothing. When Nausiakaa wakens, she takes a mule-cart and her maids, and they wash her clothing in pools by a river. They spread the wet clothing along the beach, then wash themselves and play a game in the nude. Athena has a plan for Odysseus!
