"Scylla lurks inside it – the yelping horror,
yelping, no louder than any suckling pup
but she’s a grisly monster, I assure you.
No one could look on her with any joy,
not even a god who meets her face-to-face."

– Homer

The Odyssey, Book 12, lines 94-99. Circe offers another prophecy to Odysseus about a monster he will encounter on his homeward journey. She is the creature known as Scylla, who lurks inside a cave set into an enormous crag.
