This Caucasian Soumak rug, dating back to circa 1920, showcases the traditional tribal style characteristic of its origin. Soumak rugs are known for their distinctive flat-weaving technique, which involves looping yarn horizontally around pairs of warps, resulting in a textured, durable surface. This method produces a thicker structure compared to other flatweaves like kilims. This particular piece features wool on wool construction, ensuring its resilience and robustness over time.

The primary color of this rug is blue, which dominates the background, creating a vivid and soothing effect. The border contrasts the background with a rich brick hue, framing the intricate central design. The main color, blue, pairs harmoniously with various accent colors such as red, white, yellow, and green, which are interwoven throughout the pattern.

Central to the rug's design is a prominent medallion, which presents a geometric, diamond-like shape laid sideways. This medallion features a red background filled with complex, detailed motifs in white, blue, and black. Smaller patterns within the medallion include star-shaped and cross-like elements, adding to the tapestry's intricate detail.

Surrounding the central medallion, the rug exhibits a symmetrical geometric pattern composed of various rectangular and hexagonal motifs. These motifs house smaller, detailed geometric and floral patterns, adding layers of complexity to the overall design. The symmetry in the rug is precise, with patterns and motifs on one half mirroring those on the opposite side, both horizontally and vertically.

The borders of the rug are particularly noteworthy. The outermost border features a complex pattern with zigzags and tiny floral motifs, primarily in red, white, green, and blue, enhancing the rug's vibrant aesthetic. Just inside this outer border is a narrower band in white, carrying a continuous vine or wave-like design interspersed with red and blue geometric elements.

The dense packing of the pattern, especially toward the center, showcases the skilled craftsmanship involved in creating this rug. Extensive detailing is evident in the medallion and surrounding motifs, making the rug not only a durable floor covering but also a piece of decorative art reflecting the rich cultural heritage of the Caucasus region.

This antique Soumak rug is a testament to the intricate designs and durable construction associated with traditional Caucasian tribal weaving. The rich history and cultural significance embedded in its design make it a valuable addition to any collection.
