Naranath Branthan (The madman of Naranam) is a character in Malayalam folklore. He was considered to be a divine person, a Mukhta who pretended to be mad. His chief activity consisted of rolling a big stone up a hill and then letting it fall back down. Unlike Sisyphus, he acted on his own volition rather than under the influence of a curse. There is a large statue of Naranath in Pattambi, Palakkad district of Kerala where he is believed to have lived.
Naranathu was born as the son of Vararuchi, the famous astrologer who adorned the court of Vikrama. Naranathu was one among the twelve offsprings or the Parayi petta panthirukulam(12 children born from the Pariah woman), of Vararuchi and was brought up in the Naranathu Mangalathu Mana, situated at Chethallur in Palakkad. Naranthu came to Thiruvegappura for mastering 'Vedas'. Thiruvegappura and the nearby Rayiranelloor Mountain, which is known as 'Branthachalam', became his usual abode. Due to his strange behavior and odd activities, people perceived him as 'mad'. At Rayiranellor Mountain he had the vision of the Devi (Goddess), and later for the benevolence of the people he enshrined Devi in the Mountain and started his worship there. No clear descriptions have yet been received of Naranath's last days.
The most famous facet of Naranath's life is his apparently eccentric habit of rolling big stones up the hill and letting them roll down back, and laughing thunderously on seeing this sight. However this act has been often considered allegorical and has been applied for social critiquing for myriad contexts.
