Hades (called Pluto by the Romans) was the ruler of the underworld. When the lots were drawn to determine who would rule the parts of the universe, Hades was the least lucky. He got what no one else wanted: the land of the dead. Hades did little to improve the underworld, though. he built a great palace of black stone, which was surrounded by fields called Erebus. No flowers, birds or plants were in these field, but the souls who lived in Hades often heard the fluttering of wings, which they shuddered at. Hade's companions in his world were the Erinyes, Charon, and the three-headed dog Cereberus. The Erinyes were huge monsters with large wings like metal whips, used to kill humans who displeased them, smaky hair, red eyes, and yellow teeth. Charon rowed the ferry that transferred those who had died from the land of the living to the underworld. Since Charon required payment for his service, the greek often buried their dead with a coin under their tounge. Dead sould who could not pay, stayed on the other side of the river, a kind of no-mans land. Cererbus guarded the way into Hades, and he would attack any living thing who attemped to enter the underworld. Hades was not much appriciated by the gods, but the other gods could not forbud him to visit Olympus occasionally. but when hades did visit Olympus, he was not welcome.
