Manu (Sanskrit: मनु) is a term found as various meanings in Hinduism. In early texts, it refers to the archetypal man, or to the first man (progenitor of humanity). The Sanskrit term for 'human', मानव (IAST: mānava) means 'of Manu' or 'children of Manu'. In later texts, Manu is the title or name of fourteen rulers of earth, or alternatively as the head of dynasties that begin with each cyclic kalpa (aeon) when the universe is born anew. The title of the text Manusmriti uses this term as a prefix, but refers to the first Manu – Svayambhuva, the spiritual son of Brahma.
