A unique stone statue of Narasingh deity was found while excavating a pond in Arang tehsil of Chhattisgarh's Raipur district on Thursday.
The matter came to light when some people of Kumhari village discovered the idol while deepening the pond, official sources said.
Archeologists said the idol, made up of Balua stone, seemed to be from the 4th or 5th century.
It shows Narasingh in a calm posture while most Narasingh idols show him in angry pose, ripping apart the the demon Hiranyakashyap.
Some remains of utensils of the Gupta era were also recovered from the spot, the sources said.
The idol and the utensils have been brought to Mahant Ghasidas Museum in Raipur.
