Description

　　Arab-Ata mausoleum is located in the southeast slope of the high triangle shaped hill - tepa. According to the preliminary archeological dig-out was established that mausoleum erected on the archeological monument, functioned in V-VII centuries B.C. Mausoleum enclosed in itself one square of room of 5,60 х 5,60 m. External sides 8,0 х 8,70 m. The break of square shape became according to thickening of the main facade, that has entrance niche of three meters of bay, with width 1,05 m. Laying walls have performed by the couple of bricks, divided with wide vertical sutures. This perfect constructive method, played important role in the system of architectural decor of mausoleum. Outside composition of mausoleum designates the topped with a lancet cube shaped solid dome with overflow to a main facade by a raised portal. There was placed the octahedral columns in the plan ¼. In an interior above the smooth surface of the walls is transitive octahedron to a dome with superficial arch niches on the main axes and original pendentives overlapping corners. Decorative columns placed on the corners of an octahedron. Pendentives are two-story construction. The design of the mausoleum was integrally merged with its constructive laying. Exclusively interest represented with angular columns of the transitive octahedron to a dome. It is a pentagonal in the shape. Analysis of plan and facade proportion of Arab-Ata allowed establishing presence of exact proportional mechanisms. In the basis of constructions are correlations of so-called dynamic square, i.e., progressively increasing squares in which the side of subsequent rank is equal to the diagonal of previous. The earliest monument, in which that mechanism is strictly sustained, was mausoleum of Samanids in Bukhara. The constructions of the mausoleum of Arab-Ata follow the same system. Comparison Arab-Atа with mausoleum of Samanids in Bukhara (XI-X centuries) illustrates features of their generality and at the same time evidently marks out that essentially new, that appears in the architecture of Mavaraunnakhr during that time.
