The architecture of an ancient centric dwelling in Caucasus-Pamir megaregion as a cradle of crystallization of creative ideas for dome on square

Over the course of history the architectural morphotype of the ancient centric dwelling has been continuously transformed and developed, for the Indo-European masters paid special attention to the improvement of the Domeconcept, i.e. planned composition, spatial and tectonic structure and shape. Initial place of emergence and development of the creative ideas for the dome on a square occurred in architecture of the ancient centric dwelling and subsequently held its brilliant transformation into central dome structures of memorial and religious architecture in Early Medieval Christian Eastern countries and historical Byzantium. Undoubtly, for many centuries there was a crystallization of the artistic and creative concept of the domeon on a square, arisen in ancient times. Evidences of this are the architectural creations of the centric composition, the structures and forms, built of local building materials, constituents inseparable unity, organic whole with the Caucasus-Pamir mountain mega region landscape. There is no doubt that the architectural morphotype of the ancient centric dwelling withpyramidal- ledged ceiling andlight-fluehole over an open hearth was the original basis and creative impulse in the process of forming the composition and structure of the internal space and external forms architectonic in memorial and religious structures in the early Middle Ages with Central dome, i.e. in Christian regions and the Muslim East, including the architecture of the Early and High Middle Ages in countries as Aghvan, Armenia, Georgia, Abkhazia and Alanya - all in the Caucasus, as well as Azerbaijan, Middle and Central Asia
