The rug in question is an antique Persian Kashan, crafted around circa 1930. It adheres to the traditional design characteristics associated with the Kashan style, which is renowned for its sophisticated patterns and meticulous craftsmanship.

This particular rug features a navy background and border, with blue being the primary color throughout the design. The material composition is wool on cotton, which is a common combination for Kashan rugs, providing both durability and a plush texture.

A key feature of this rug is its central medallion, an intricately designed element adorned with floral motifs. The medallion, predominantly blue with red, beige, and light blue accents, forms a classic shape with peaks and scallops. This central element seamlessly integrates with the surrounding floral patterns, creating a cohesive and elaborate design.

The overall pattern is densely populated with floral elements, including vines, stems, flowers, and leaves, rendered in shades of beige, red, blue, and light blue. The symmetrical design along both the vertical and horizontal axes ensures a harmonious and balanced appearance.

The borders of the rug are composed of multiple, intricately designed layers. The inner border is narrow, featuring small, repeating floral motifs in colors such as beige, light blue, and red against a dark background. The second border, slightly wider, contains a repetitive series of small floral elements that complement the inner border. The outer border, the widest of the three, is densely packed with similar small floral motifs, and the rug's edge is finished with a simple strip in a rust or terracotta tone.

This rug exemplifies the characteristics of Kashan rugs, which are known for their intricate designs, fine materials, and exceptional craftsmanship. It represents a piece of the rich weaving tradition of Kashan, reflecting the historical and artistic significance of Persian rug making.
