Moly Root
Circe falls in love with a mortal called Glaucos, and gives him the moly root, which transforms him into a god. This root is symbolic as it makes Circe realize that she does have powers of transformation.
Ships
In the novel, ships represent the unknown and the liminal. Indeed, ships exist as a space between two places, and therefore also represent Circe's transformation. Circe meets Glaucos on a ship and later travels on ships herself in order to explore and reach new destinations.
The Pigs
Circe is sexually assaulted while on Aiaia, and as revenge, she decides to turn the male visitors on the island into pigs. Here, the dirtiness of the pigs is used to physically manifest the immorality of the men.
