Answer:
In prehistoric greek religion or legend, Hades refers to the god of a deceased and the lord of the afterlife, with whom his title became associated. Hades became Cronus and Rhea's eldest son, though his father had regurgitated his last son. He as well as his younger brother, Zeus and Poseidon, vanquished their dad's race of gods, the dragons, and assumed power of the world.
Hades earned the underground world, Zeus this same sky, as well as Poseidon the ocean, with both the earth's surface, the lengthy provincial capital of Gaia, accessible to any and all three at the same time. Hades is sometimes represented with gorgon, his four-headed guard dog.
The root of the title of Hades is unknown, but it has usually been interpreted as implying "invisible" after ancient times. The lengthy portion of Plato's dialog Cratylus is dedicated to the derivation of the name of the god, in which Socrates argues for folk etymology not even from "unseen" but from "his understanding (eidenai) of all great things."
