In a narrow strait of churning water, sailors faced a choice with no good answer: steer too close to one shore and a whirlpool would swallow the whole ship; steer too close to the other and a six-headed monster would pluck the men from the deck one by one. That monster was Scylla — and to pass her was to lose someone, always.
The Six-Headed Horror of the Strait
Scylla lurked in a cliffside cave above a narrow sea-passage. From the waist up she appeared a woman, but around her body grew six long, snaky necks, each ending in a ghastly head with three rows of teeth, and a girdle of barking dogs' heads at her waist. As ships passed beneath, she would dart out her six heads and snatch six sailors at once, devouring them alive in her cave.
A Beauty Turned to a Monster
Like Medusa, Scylla was not born monstrous. In the most famous version she was a beautiful sea-nymph loved by the sea-god Glaucus — but the jealous sorceress Circe, who wanted Glaucus for herself, poisoned the pool where Scylla bathed. When Scylla stepped in, her lower body erupted into the writhing dogs and serpent-necks. Driven mad by her transformation, she became the man-eating terror of the strait — another beautiful woman remade into a monster by a god's jealousy.
Between Scylla and Charybdis
Her most famous appearance is in Homer's Odyssey. Forced to sail the narrow strait, Odysseus was warned he could not avoid both perils: the whirlpool Charybdis on one side would destroy his entire ship, while Scylla on the other would take only six men. He chose Scylla — and watched, helpless, as she snatched six of his crew, “calling out my name for the last time.” To be caught “between Scylla and Charybdis” still means to be trapped between two equally deadly dangers.
Some passages cannot be made without loss — the only choice is which loss you can bear.
