Vikramkhol Cave Inscription is located 12 km distance from Belpahar. It is about 35 km away from Jharsuguda. In this inaccessible dense forest Ancient people lived surviving on fruits, roots and animal meat. During 4000 BC, there was an evolution of human civilization in the region and a script was developed by them. There is some ancient script engraved on the wall of Bikramkhol and also paintings of animals. Circular holes have been dug in the wall where weapons, dresses and other articles of use were being kept suspended. Even on the floors, circular holes have been dug to pound the grains. Bikramkhol cave has been declared a tourist spot by the Central Government, Odisha Tourism, historians and researchers from all over the country and abroad.
Vikramkhol cave bears the relics of the proto-historic age. The natural rock Shelter containing the pictographic relics is 34.8 meters in length and 8.3 meters in height. The inscribed portion is 10.7 meters, where some letters are carved out while others are painted ochre. The letter retains the original Brahmi from Dr A.P. Jayaswal remarks’ the writing is certainly earlier than the earliest specimen of ‘Brahmi’ known so far and ‘Brahmi’ was completed before 1500 B.C. . We would be within the range of fair approximation in dating it about 1500 B.C. The replica of these inscriptions is seen at Odisha State Museum in Bhubaneswar. Source
