Artemis appears in the story only as a comparison. When Odysseus crawls out of the leaves on the Phaeacian shore, blood-crusted, naked, more animal than man, and sees Nausicaa standing among her maids by the river, he asks if she is a goddess. Artemis, perhaps. The huntress. Tall, swift, untouchable. It is the politest thing a desperate stranger can say to a king’s daughter. The line tells you what kind of presence the girl has and what kind of mind Odysseus still has even at the bottom of his fortunes. He can read a situation in seconds and find the exact word that will not get him killed. Artemis does not act in the story. She is a measure, the way you would say of someone that they walked like a queen.
Artemis
Huntress goddess. Invoked once, when Odysseus first sees Nausicaa and tries to figure out whether she's mortal.
