The Ramayana (_Rama_ and _yana_, expedition) describes the exploits of Rama, an incarnation of Vishnu, and the son of Dasaratha, king of Oude. Ravana, the prince of demons, bad stolen from the gods the privilege of being invulnerable, and had thus acquired an equality with them. He could not be overcome except by a man, and the gods implored Vishnu to become incarnate in order that Ravana might be conquered. The origin and the development of this Avatar, the departing of Rama for the battlefield, the divine signs of his mission, his love and marriage with Sita, the daughter of the king Janaka, the persecution of his step-mother, by which the hero is sent into exile, his penance in the desert, the abduction of his bride by Ravana, the gigantic battles that ensue, the rescue of Sita, and the triumph of Rama constitute the principal plot of this wonderful poem, full of incidents and episodes of the most singular and beautiful character. Among these may be mentioned the descent of the goddess Ganga, which relates to the mythological origin of the river Ganges, and the story of Yajnadatta, a young penitent, who through mistake was killed by Dasaratha; the former splendid for its rich imagery, the latter incomparable for its elegiac character, and for its expression of the passionate sorrow of parental affection. The Ramayana was written by Valmiki, a poet belonging to an unknown period. It consists of seven cantos, and contains twenty-five thousand verses. The original, with its translation into Italian, was published in Paris by the government of Sardinia about the middle of this century.
