Circe

Circe was a witch who lived in ancient Greece, specifically the island of Circe's Island. She enjoyed transfiguring lost sailors into guinea pigs.^[1]

Biography

Circe was featured on a Chocolate Frog Card. Harry Potter obtained this card from a Chocolate Frog on his first trip to Hogwarts in 1991.^[2] There was a portrait of Circe at Hogwarts Castle. It guarded a secret shortcut between the fourth-floor landing of the Grand Staircase and the Entrance Hall side room. The password required to gain access to said shortcut was GuineaPiggyWiggy.^[3]

Magical abilities and skills

• Transfiguration: Circe was proficient in the human to guinea pig spell, as she enjoyed turning Sailors into guinea pigs; an accomplishment in the fact that guinea pigs are considered extremely un-magical, showing she was highly talented in this very difficult, complex and even dangerous branch of magic. The most notable transfiguration was in Sea of Monsters, when she turned Percy Jackson into a guinea pig.

Behind the scenes

• Circe was a minor goddess in Greek mythology, said to transform sailors lost around her island of Aeaea into animals via the use of enchanted food. She is perhaps most well known as a figure in Homer's Odyssey, where the hero Odysseus spent a year on her island after freeing his shipmates from her spells.
