Proto-Indo-European religion

Proto-Indo-European religion is not directly attested, but reconstruction has been attempted based on the existence of similarities among the deities, religious practices and mythologies of the Indo-European peoples. The hypothesized reconstructions below are based on linguistic evidence using the comparative method. Archaeological evidence is difficult to match to any specific culture in the period of early Indo-European culture in the Chalcolithic. Other approaches to Indo-European mythology are possible, most notably the trifunctional hypothesis of Georges Dumézil.
