Another small group of Ushak carpets is called Double-niche Ushaks. In their design, the corner medallions have been moved closely together, so that they form a niche on both ends of the carpet. This has been understood as a prayer rug design, because a pendant resembling a mosque lamp is suspended from one of the niches. The resulting design scheme resembles the classical Persian medallion design. Counterintuitive to the prayer rug design, some of the double niche Ushaks have central medallions as well. Double niche Ushaks thus may provide an example for the integration of Persian patterns into an older Anatolian design tradition.
