1. The bull capital of Ashoka from Rampurva, Bihar, also belonging to the third century B.C. is an interesting study as it is a mixture of Persian and Indian elements. The lotus capital is entirely formalistic. The motifs on the abacus are beautiful decorative elements like the rosette, palmette and the acanthus ornaments, none of them Indian.
2. However, the crowning element of the bull capital, that is the bull proper, is a master-piece of Indian craftsmanship, showing a humped bull, well modelled, with its soft flesh beautifully represented, with its strong legs, sensitive nostrils and the ears cocked as if it were listening.
