The most famous survivals are the large animals surmounting several of the Pillars of Ashoka, which showed a confident and boldly mature style and craft and first of its kind iron casting without rust until date, which was in use by vedic people in rural areas of the country, though we have very few remains showing its development. The famous detached Lion Capital of Ashoka, with four animals, was adopted as the official Emblem of India after Indian independence. Mauryan sculpture and architecture is characterized by a very fine Mauryan polish given to the stone, which is rarely found in later periods.
