Besides others, there are in the infernal regions the following monsters:--The Centaurs, whose upper parts are human, but whose bodies and legs are those of a horse. They were begotten of a cloud by Ixion. Gorgon is a monster with three heads. The Harpies, born of Oceanus and Terra, have the faces of virgins, and the bodies of birds with claws. Their names are Ocypete, Aello, and Celeno. The Gorgons are Medusa, Stheno, and Euryale, daughters of Phorcys and Cete. They have heads covered with snakes instead of hair, which so terrifies beholders that they immediately turn into stones. The Lamiæ and Empusæ have each only one eye and one tooth. They have faces, necks, and breasts like women, but their bodies are covered with scales, and they have the tails of serpents. The Chimœra is a monster that vomits fire, and has the head and breast of a lion, the belly of a goat, and the tail of a dragon. The Sphinx, begotten of Typhon and Echidna, has the head and face of a virgin, the wings of a bird, and the body of a dog. A riddle she put forth being explained by Œdipus, so enraged her that she threw herself from a rock and was killed. The most famous of the condemned in the place of punishment are the Giants; they are great in stature, and have horrible feet, like dragons. They make war against the celestial gods, but never prevail, and are struck down to hell by Jupiter's thunder-bolts and the arms of the gods. The principal offenders are Typhon, Ægæon, Alœus, and Tityus; and, to prevent them rising again, the Island of Sicily is fixed on Typhon, and Mount Ætna on Ægæon, and Tityus is doomed to have a vulture always gnawing his liver, which grows afresh every month. Phlegias fired Apollo's temple at Delphi, for which he was sentenced to have a great stone hung over his head, ready every moment to fall and crush him to pieces. Ixion, for an assault on Juno, was struck down to hell, and tied to a wheel, which kept continually turning. Sisyphus is a notorious robber, condemned to roll a stone up to the top of a hill, which is made to roll down again immediately; and as he has to begin and roll it up again as soon as it comes down, his labour is perpetual. The Danaides are fifty virgins (sisters), who all but one, by the command of their father Danaus, slew their husbands on their wedding night. For this they were condemned to draw water out of a deep well, to fill a tub whose bottom was full of holes like a sieve. Tantalus invited the gods to a feast, and, to improve their divinity, he killed, boiled, and served up Pelops on the table before them to eat. They refused to partake of this horrid dish, and condemned Tantalus to stand in water which he could not drink, and to have meat placed before him which he could not taste, though suffering the pangs of hunger and thirst--a punishment he was to endure for ever.
