HADES Also known as Pluto, or Aides, he was the dark, grim god of the underworld, and ruled supreme there. He was a son of Rhea, and like his brothers Zeus and Poseidon, demanded a share of the Earth following the overthrow of Kronos. The three siblings cast lots, and to Hades fell the world below. His domain was a bleak one:the three rivers running along its environs were named Styx, Acheron (the river of eternal woe), Pyriplegethon (the stream of fire), Kokytos (the river of weeping and wailing) and Lethe (the river of forgetfulness). Once someone had passed over into the realm of Hades, there was no return (except in the case of Orpheus. Charon, the aged boatman of the dead, ferried the souls of the departed across the river Styx, which flowed into Hades, and once there they were received by Hades and his wife, Persephone.
