Vishwakarma is the term used in India for a caste of priests, engineers, architects, sculptors, temple builders and artists. The term is applied to five sub-castes; blacksmiths, carpenters, copper smiths, goldsmiths and sculptors.
Vishwakarma Brahmins are also called Rathakara Brahmins, and the Rathakara mentioned in the Rigveda (1.6.32) indicates high status and is associated with the placing of the holy sacrificial fire in the Yajna kunda. According to the Srautasutras, the Rathakara (Chariot-maker) is entitled to perform all the sacrifices. In many sacrifices, like the Rajasuya, the Rathakara played a role as recipient of the offerings (ratninaḥ).
