Hades is the lord of the dead and ruler of the nether world, which is referred to as the domain of Hades or, by transference, as Hades alone. He owns all the wealth in the ground and the people referred to him as the Rich One. They were frightened to say his real name for fear that it would attract his attention. Black sheep were offered to him, and the sacrifice was performed with the face averted. Mortals who enter his world had no hope of returning, and so Hades was characterized as pitiless and inexorable. Hades had abducted Persephone and made her his wife.
