From the recording Echoes of Ancient Greece
Hades ("The unseen"), was the god of the underworld and the name eventually came to also describe the home of the dead as well. He was the oldest male child of Cronus and Rhea.
Hades and his brothers Zeus and Poseidon defeated their father and the Titans to end their reign, claiming rulership over the cosmos. They agreed to split their rule with Zeus becoming god of the skies, Poseidon god of the sea and Hades god of the underworld.
He was later known to the Greeks as Plouton, which the Romans pluralized to Pluto. The god of the underworld was married to Persephone, the daughter of Demeter, whom he obtained through deception after abducting her to the underworld and giving her the forbidden fruit pomegranate, forcing her to remain in the underworld with him for one third of each year.
