Mythology says that Kerala was created from the Arabian Sea and given to the Brahmins (Namboothiris) as a "donation" by Parasurama to save himself from the sins of killing numerous kshathriya kings. The land was full of forests and poisonous snakes were found in plenty. So the Brahmins refused to stay there. Parasurama requested Lord Shiva to provide a solution. Shiva told Parasurama to start worshipping Anantha and vasuki the king of snakes. Parasurama did so and Anantha advised him to start snake worship in Kerala and provide some forest especially for snakes in the form of Sarppakkavu (Snake forests). Parasurama later installed the idols of Anantha and Vasuki at Vettikkottu (near Kayamkulam in Alappuzha district) and Mannarassala (near Harippadu in Alappuzha district) and started worshipping them. The Brahmins also worshipped Anantha and Vasuki and the pleased snake gods made Kerala suitable for living.
