 Ananda Coomaraswamy, writing in 1923, argued that the Mauryan art has three main phases.The first phase is found in some instances of the representation of the Vedic deities (the most significant examples are the reliefs of Surya and Indra at the Bhaja Caves).However the art of the Bhaja Caves is now generally dated later than the Mauryan period, to the 2nd-1st centuries BCE.
