The Geometric Late 19th Century Antique Caucasian Shirvan Islamic Prayer Design Rug is an exceptional example of tribal artistry from the Shirvan region of the Caucasus Mountains. Hand-knotted in the 1890s using high-quality wool, this collectible antique rug features a mesmerizing geometric lattice field with repeating diamond medallions and stylized boteh motifs. The design is anchored by a rich indigo blue ground, contrasted with natural ivory, camel, and madder red tones achieved through traditional natural dyes. A subtle mihrab element at the top highlights its prayer design, while the allover pattern ensures visual depth. This small scatter-sized rectangular rug serves as a powerful historical accent for an entryway, study, or intimate seating area, offering a 0.5-inch pile height and remarkable design clarity.
