 Notably, the Rigveda differentiates between the "Ratha" (chariot) and the "Anas" (often translated as "cart").Rigvedic chariots are described as made of the wood of Salmali (RV 10.85.20), Khadira and Simsapa (RV 3.53.19) trees.While the number of wheels varies, chariot measurements for each configuration are found in the Shulba Sutras.
