The earliest Indian paintings were the rock paintings of prehistoric times, the petroglyphs as found in places like Bhimbetka, and some of them are older than 5500 BC. Such works continued and after several millennia, in the 7th century, carved pillars of Ellora, present a fine example of Indian paintings. Thereafter, frescoes of Ajanta and Ellora caves appeared. Indian paintings provide an aesthetic continuum that extends from the early civilization to the present day. From being essentially religious in purpose in the beginning, Indian painting has evolved over the years to become a fusion of various cultures and traditions. The Indian painting was exposed to Greco-Roman as well as Iranian and Chinese influences.
