In the description given by Homer, in the twelfth book of the 'Odyssey,' of the unfortunate nymph Scylla, transformed by the arts of Circe into a frightful monster, the same typical idea as in the case of the Hydra is perceptible. The lurking octopus, having its lair in the cranny of a rock, watching in ambush for passing prey, seizing anything coming within its reach with one or more of its prehensile arms, even brandishing these fear-inspiring weapons out of water in a threatening manner, and known in some localities to be dangerous to boats and their occupants, is transformed into a many-headed sea monster, seizing in its mouths, instead of by the adhesive suckers of its numerous arms, the helpless sailors from passing vessels, and devouring them in the abysses of its cavernous den.
Circe, prophesying to Ulysses the dangers he had still to encounter, warned him especially of Scylla and Charybdis, within the power of one of whom he must fall in passing through the narrow strait (between Italy and Sicily) where they had their horrid abode. Describing the lofty rock of Scylla, she tells him:
"Full in the centre of this rock displayed A yawning cavern casts a dreadful shade, Nor the fleet arrow from the twanging bow Sent with full force, could reach the depth below. Wide to the west the horrid gulf extends, And the dire passage down to hell descends. O fly the dreadful sight! expand thy sails, Ply the strong oar, and catch the nimble gales; Here Scylla bellows from her dire abodes; Tremendous pest! abhorred by man and gods! Hideous her voice, and with less terrors roar The whelps of lions in the midnight hour. Twelve feet deformed and foul the fiend dispreads; Six horrid necks she rears, and six terrific heads;
When stung with hunger she embroils the flood, The sea-dog and the dolphin are her food; She makes the huge leviathan her prey, And all the monsters of the wat'ry way; The swiftest racer of the azure plain Here fills her sails and spreads her oars in vain; Fell Scylla rises, in her fury roars, At once six mouths expands, at once six men devours."[72]

Circe then describes the perils of the whirling waters of Charybdis as still more dreadful; and, admonishing Ulysses that once in her power all must perish, she advises him to choose the lesser of the two evils, and to
