Ravana, in the Hindu mythology the king of the demons, who carried off Sita, the wife of Râma, to Ceylon, which, with the help of the monkey-god Hanuman, and a host of quadrumana, Râma invaded and conquered, slaying his wife's ravisher, and bringing her off safe, a story which forms the subject of the Hindu epic, “Râmâyana.”
