Indo-European mythologies
Proto-Indo-European religion is the belief system adhered to by the Proto-Indo-Europeans. Although this belief system is not directly attested, it has been reconstructed by scholars of comparative mythology based on the similarities in the belief systems of various Indo-European peoples.
Various schools of thought exist regarding the precise nature of Proto-Indo-European religion, which do not always agree with each other. Vedic mythology, Roman mythology, and Norse mythology are the main mythologies normally used for comparative reconstruction, though they are often supplemented with supporting evidence from the Baltic, Celtic, Greek, Slavic, and Hittite traditions as well.
The Proto-Indo-European pantheon includes well-attested deities such as *Dyḗus Pḥatḗr, the god of the daylit skies, his daughter *Haéusōs, the goddess of the dawn, the Horse Twins, and the storm god *Perkwunos. Other probable deities include *Péh2usōn, a pastoral god, and *Seh2ul, a Sun goddess.
Well-attested myths of the Proto-Indo-Europeans include a myth involving a storm god who slays a multi-headed serpent that dwells in water, a myth about the Sun and Moon riding in chariots across the sky, and a creation story involving two brothers, one of whom is sacrificed by the other in order to create the world. The Proto-Indo-Europeans may have believed that the Otherworld was guarded by some kind of watchdog and could only be reached by crossing a river. They also may have believed in some kind of world tree, bearing fruit of immortality, either guarded by or gnawed on by a serpent or dragon of some kind and tended to by three goddesses, who were believed to spin the thread of life.
