An early INDO-EUROPEAN language, still used in India for religious purposes. The RIGVEDA, the oldest religious document of India, is written in an archaic form of Sanskrit. The discovery in the late 18th century that this language was related to Greek and Latin and many other European languages led to the development of the discipline of comparative philology.
