In Hindu mythology, "Manu" is the name of the traditional progenitor of humankind who survives a deluge and gives mankind laws. The hypothetically reconstructed Proto-Indo-European form "*Manus" may also have played a role in Proto-Indo-European religion based on this, if there is any connection with the figure of "Mannus" — reported by the Roman historian Tacitus in ca. AD 70 to be the name of a traditional ancestor of the Germanic peoples and son of Tuisto; modern sources other than Tacitus have reinterpreted this as "first man".
