Snake worshipping is one of the traditions of the ancient Indian culture. Naga Panchami, the day of snake is celebrated in the month of Shravan (July-August). In Bihar, terracotta images of snake couples are offered as a part of worship. In Madhya Pradesh, people paint snakes with four, sixteen or twenty-one knots and in Rajasthan, the hooded snake is made in relief on a terracotta plate.
