What we know of early Indo-European mythology in India comes to us more from the Rigveda than from anywhere else. The Rigveda contains creation myths, a cosmology, and a series of early pantheons governed by triads such as the one in which Varuna, Mitra, and Aryaman—all solar deities—dominate, and then by Indra, Agni, and Surya, who replace them, at least in name. Because there are contradictions between mythical elements of the Rigveda and those of other sacred and semi-sacred texts and within the Vedas itself, it can be assumed that the myths are metaphors relating to various aspect of life rather than stories to be taken literally, even by believers.
