The origin of the legal procedure of the Roman-Byzantine rite of the emperor coronation

The article deals with the problem of the origin of the Roman-Byzantine rite of the coronation of the emperor in the context of the evolution of the Greco- Iranian symbiosis that began after the conquests of Alexander the Great. According to the author, the wars of diadochs and epigones, the expansion of the Parthian kingdom led to the development of ideas about the military legitimization of political power, which reached its apogee in the Sasanian era. The Greco-Iranian, Hellenistic, sources of the Byzantine emperor’s coronation ceremony, perceived through the mediation of the Roman army, allow us to conclude that this ceremony had ancient pagan roots. This fact predetermined the fact that the Orthodox Church was striving for the consistent churching of this ceremony, its liturgical consecration, and, consequently, for its Christian reinterpretation in the bowels of the canonical tradition.
