<P> Indian painting has a very long tradition and history in Indian art . The earliest Indian paintings were the rock paintings of pre-historic times, the petroglyphs as found in places like Bhimbetka rock shelters, some of the Stone Age rock paintings found among the Bhimbetka rock shelters are approximately 30,000 years old .

Smaller scale painting in manuscripts was probably also practised in this period, though the earliest survivals are from the medieval period . Mughal painting represented a fusion of the Persian miniature with older Indian traditions, and from the 17th century its style was diffused across Indian princely courts of all religions, each developing a local style . Company paintings were made for British clients under the British raj, which from the 19th century also introduced art schools along Western lines, leading to modern Indian painting, which is increasingly returning to its Indian roots . </P> <P> Indian paintings provide an aesthetic continuum that extends from the early civilisation to the present day .

Vatsyayana, who lived during the third century A.D., enumerates these in his Kamasutra having extracted them from still more ancient works . </P> <P> These' Six Limbs' have been translated as follows: </P>
