====Structural peculiarity theory====
{{main|Trifunctional hypothesis}}
In several of his works, [[G. Dumézil]] proposed the existence of a structural difference in level between the [[Proto-Indo-European gods]] of beginning and ending, and the other gods whom Dumézil postulated fall into [[Trifunctional hypothesis|a tripartite structure]], reflecting the most ancient organization of society. So in [[Proto-Indo-European religion|IE religions]] there is an introducer god (such as [[Vedic]] [[Vâyu]] and Roman Janus) and a god of ending, and a nurturer goddess who is often also a fire spirit (such as Roman [[Vesta (mythology)|Vesta]], Vedic [[Saraswati]] and [[Agni]], [[Avestic]] [[Armaiti]] and [[Anahita|Anâitâ]]) who show a sort of mutual solidarity.

The concept of 'god of ending' is defined in connection to the human point of reference, i.e. the current situation of man in the universe, and not to endings as transitions into new circumstances, which are under the jurisdiction of the gods of beginning, owing to the ambivalent nature of the concept. Thus the god of beginning is not structurally reducible to a sovereign god, nor the goddess of ending to any of the three categories on to which Dumézil distributed goddesses. There is though a greater degree of fuzziness concerning the function and role of goddesses, which may have formed a preexisting structure allowing the absorption of the local Mediterranean mother goddesses, nurturers, and protectresses .<ref name=Dumézil-1946>{{cite book |author=Dumézil, G. |author-link=Georges Dumézil |year=1946 |section=De Janus à Vesta |title=Tarpeia |place=Paris, FR |pages=33–113}}</ref><ref>{{cite book |author=Marconi, M. |title=Riflessi mediterranei nella piú antica religione laziale |place=Milan, IT |year=1940}}</ref>

As a consequence, the position of the gods of beginning would not be the issue of a diachronic process of debasement undergone by a supreme sky god, but rather a structural feature inherent to the culture's theology. The descent of primordial sky gods into the condition of ''[[deus otiosus]]'' is a well-known phenomenon in many religions.
Dumézil himself observed and discussed in many of his works the phenomenon of the fall of archaic celestial deities in numerous societies of ethnologic interest.<ref>{{cite book |author=Eliade, M. |author-link=Mircea Eliade |year=1949 |title=Traité d' histoire des religions |place=Paris, FR |page=53}}<br/> {{cite book |author=Eliade, M. |author-link=Mircea Eliade |year=1950 |title=Le chamanisme et les techniques archaiques de l'ecstase |place=Paris, FR |at=ch.&nbsp;VI 1}}</ref>
