The Rigveda is an ancient Indian sacred collection of Vedic Sanskrit hymns. It is counted among the four canonical sacred texts (Åruti) of Hinduism known as the Vedas. Some of its verses are still recited as Hindu prayers, at religious functions and other occasions, putting these among the world's oldest religious texts in continued use. It is one of the oldest extant texts in any Indo-European language. Philological and linguistic evidence indicate that the Rigveda was composed in the north-western region of the Indian subcontinent, roughly between 1700-1100 BC.
