Once upon an uncomputable time past, there was a king bearing the name of Mahajanaka who reigned in the city of Mithila in the land of Videha. King Mahajanaka had two sons named respectively Aritthajanaka and Polajanaka. The elder son was invested by the King as Viceroy, and the younger one, Chief Minister. In the course of time, the King passed away to Heaven. Prince Arithajanaka acceded to the throne and invested his brother as Viceroy.
