The niche design represented here is similar to the double niche arrangement on a rug formerly in the Christopher Alexander collection (C. Alexander, A Foreshadowing of 21st Century Art, New York 1993, p. 279). Alexander makes an interesting parallel between the niche motif seen here and the Kufic element seen on the border of some of the famous Seljuk period rugs at the TIEM in Istanbul. He also notes that the spotted motifs, seen here inside the blue profile of the niche, date back to the Middle Ages.
