298. CERBERUS, the dog which guarded the lower regions. This stanza is an imitation of Vergil's _Æneid_, vi, 417 _seq_. In Dante's _Inferno_ Vergil appeases him by casting handfuls of earth into his maw. xxxv. In this stanza we see the influence of Homer and Vergil. Ixion, the king of Lapithæ, was chained by order of Zeus to a fiery-winged wheel for aspiring to the love of the goddess Hera (Juno). Sisyphus had to roll a huge stone forever up a hill for betraying the designs of the gods. Tantalus, for divulging the secrets of Zeus, was condemned to stand tormented by thirst in a lake. Tityus, for an assault on Artemis, was pinioned to the ground with two vultures plucking at his vitals. Typhoeus, a hundred-headed giant, was slain by Zeus' thunderbolt, and buried under Ætna. The gin on which he was tortured was probably the rack of the Middle Ages. Cf. the bed of Procrustes. Theseus, for attempting to carry off Persephone, was fixed to a rock in Tartarus. The "fifty sisters" are the fifty Danaides, who, for slaying their husbands, were condemned to pour water forever into a vessel full of holes.
