Obscurity shrouds the period between the decline of the Harappans and the definite historic period starting with the Mauryas, and in the historical period, the earliest Indian religion to inspire major artistic monuments was Buddhism. Though there may have been earlier structures in wood that have been transformed into stone structures, there are no physical evidences for these except textual references. Soon after the Buddhists initiated rock-cut caves, Hindus and Jains started to imitate them at Badami, Aihole, Ellora, Salsette, Elephanta, Aurangabad and Mamallapuram and Mughals. It appears to be a constant in Indian art that the different religions shared a very similar artistic style at any particular period and place, though naturally adapting the iconography to match the religion commissioning them. Probably the same groups of artists worked for the different religions regardless of their own affiliations.
