Αία, also known as Aiaia, is a mythical island in Greek mythology, famously associated with the enchantress Circe. It is depicted as a place where Circe lived and practiced her magic, transforming men into animals. The island is often described as lush and beautiful, surrounded by the sea. In Homer's epic, the Odyssey, the hero Odysseus visits Αία after his long journey. There, he encounters Circe, who initially turns his crew into swine but later helps them. Αία serves as a significant location in Odysseus' adventures, symbolizing both danger and transformation.
