What is the name of the enchanted island Odysseus visits?

The enchanted island that Odysseus visits is Aiaia. This island is most notably associated with the witch-goddess Circe, who transforms Odysseus's crew into animals and later advises him on his journey home. Aiaia serves as a significant turning point in Odysseus's adventures, where he learns crucial information that helps him navigate the challenges he faces on his way back to Ithaca.

Thrinacia, while another island associated with Odysseus’s journey, is the island of the Sun God Helios, where his crew meets their fate by consuming the sacred cattle. Phaeacia is known for being the home of the Phaeacians, who ultimately help Odysseus return to Ithaca by providing him with ships and resources. Scheria is another name for Phaeacia, rather than a distinct location. Therefore, Aiaia is the correct answer as it is where Odysseus encounters Circe and undergoes significant developments related to his character and journey.
