Vamana (Devanagari: वामन, IAST: Vāmana) is described in the Puranic texts of Hinduism as the Fifth Avatar of Vishnu, and the first incarnation of the Second Age, or the Treta yuga. Also he is the first Avatar of Vishnu which appears with a completely human form, though it was that of a dwarf brahmin. He is also sometimes known as Upendra.
