The Sea Nymphs are the Nereides already referred to. The Naides or Naiades preside over fountains and springs; the Potameides preside over rivers, and Limniades over lakes. In noticing the Infernal Deities, we shall describe the dismal regions, where wicked spirits dwell, and over which they are reported to preside. The name commonly given to these regions is Hades or Tartarus, understood to signify hell. The passage leading thereto is a wide dark cave, through which one has to pass by a steep rocky descent till he arrives at a gloomy grove and an unnavigable lake called Avernus, from which such poisonous vapours rise as to kill birds flying over it. Yet over this lake the souls of the dead must pass. To assist them, an old decrepit, long-bearded fellow, the oft-heard of Charon, attends with a ferry-boat to carry them to the other side, at a fare not less than a halfpenny. After this there are four rivers to be passed over--Acheron, whose waters are very bitter; the Styx, a lake rather than a river, and so sacred to the gods, that if any of them swore by it and broke his oath, he was deprived of his godhead, and was prohibited from drinking nectar for a hundred years; the river Cocytus, which flows out of Styx with a lamentable groaning, resembling the painful sounds and exclamations of the damned; the river Phlegethon, so called because it swells with waves of fire and streams of flames. The souls having passed these rivers, are conducted to the palace of Pluto, king of the infernal regions, where the gate is guarded by Cerberus, a dog with three heads, whose body is covered with snakes in place of hair. This dog is the porter of hell. Pluto initiated funeral obsequies for the dead: he sits on a throne covered with darkness, holding a key in his hand, and crowned with ebony. Beside him is his queen Proserpina, whom he stole from Ceres. Minos, Æacus, and Rhadamanthus are judges in hell. The first two are sons of Jupiter by Europa, and the last is his son by Ægina. These are believed to judge the souls of the dead. The Fates are named Clotho, Lachesis, and Atropos, and are the goddesses of destiny. They order and manage the fatal thread of life. Clotho draws the thread, Lachesis turns the wheel, and Atropos cuts the string asunder when spun to a due length. The Furies, called sometimes Eumenides, Diræ, and Manes, are the daughters of Nox and Acheron: their names are Alecto, Tisiphone, and Megæra, and are known by the common name of Erinnys. They have faces like women, their looks are full of terror, they hold lighted torches in their hands, and snakes and serpents cling to their necks and shoulders. Their office is to punish the crimes of wicked men, and to torment and frighten them by following them with ghastly looks and burning material. Erebus and Nox preside over darkness and the night; Mors over death; and Somnus is the god of sleep, who, by his servant Morpheus, sends dreams to men while asleep.
