This late 19th-century antique Caucasian Shirvan prayer rug is a superlative example of the scholarly tribal style from Azerbaijan. Hand-knotted from high-quality wool, it features a rare ivory field traditionally reserved for special commissions. The central Mihrab prayer niche is surrounded by intricate geometric motifs, including star-rosettes and stylized boteh, rendered with mathematical accuracy. A vibrant palette of natural vegetable dyes like indigo blue, madder red, and saffron yellow has developed a soft patina over 130 years. With a crisp 0.5-inch pile height and a sophisticated rectangular shape, this rug showcases extraordinary fine knotting and a silken sheen. The iconic borders provide a regal frame, making this historic piece a timeless addition to any space.
