Scylla is a figure in Greek and Roman mythology best known as a sea monster in Homer's *Odyssey*, where she threatens sailors passing through a narrow strait with Charybdis. In later tradition, Scylla was sometimes described as a beautiful nymph transformed into a monster, though earlier accounts present her simply as monstrous. The name also appears in other mythological figures, including a princess of Megara and a Danaid.
