Everyone knows the witch who turned sailors into pigs, but Circe’s story has been rewritten for millennia. This deep dive traces her biography from her birth to Helios and the oceanid Perse, with siblings Aeetes and Pasiphae, through the early myths where rejection by Glaucus and Picus leads her to transform the innocent nymph Scylla into a monster and a king into a woodpecker. It reads her earthly, botanical magic as a source of unique terror for ancient Greeks used to gods hurling thunderbolts from afar, and as a projection of patriarchal anxiety about autonomous women.

The episode then examines the famous encounter with Odysseus, the herb moly from Hermes, and the pivot from threat to mentor as Circe supplies the map through the underworld. It follows the strange aftermath in the lost epic Telegony, where her son Telegonus kills Odysseus and cross-marriages tie her bloodline to the founding of Italian cities. From there it tracks her philosophical reinvention in Plutarch’s Gryllus, where a pig argues that animals are more virtuous than humans, her treatment as temptress by writers from Alciato to James Joyce, and her reclamation by poets like Augusta Webster, H.D., and Carol Ann Duffy. It closes with medical historians who read the pig transformation as anticholinergic poisoning from jimsonweed and moly as the snowdrop, whose galantamine reverses it.
