Once upon a time, there was a dense forest adjoining a village. An evil demon used to come daily to take away a child for his dinner. One day, a clever man put mirror in front of his cave. Demon got angry when he saw his replica in mirror and attacked on it. The mirror broke and his image multiplied on the broken pieces. He got scared and his heart stopped beating. The villagers did not believe and dare to see themselves the dead demon. The clever man had to paint the sequence of events to convince them. Thus the man was considered as the pioneer of the Patua paintings.
