This Persian Kashan rug, woven circa 1940, showcases the traditional and intricate design elements characteristic of this renowned region. The rug features a beige background with a contrasting blue border, making use of high-quality wool on a cotton foundation, typical of Kashan's textile craftsmanship during this period.

Kashan, a city with a rich history in Persia (modern-day Iran), has long been celebrated for its weaving mastery. Its reputation was particularly solidified during the Safavid era, noted for its high-quality silk production. While this particular rug is made of wool, it benefits from the deep-rooted weaving traditions that emphasize excellence and durability.

The design of this rug presents a dense floral pattern, where various flower motifs are intricately entwined with vines and leaves across the entire surface. This foliage-themed design features a harmonious array of colors, including dark blues for the border, light blues, hints of green, and earthy browns for the central motifs. These colors enhance the visual appeal and depth, highlighting the meticulous craftsmanship involved in its creation.

Framing the central field is a series of borders, starting with an outermost wide border adorned with elaborate floral and vine patterns. This border is densely packed with larger floral medallions and vine motifs, which echo the intricate design of the central field but on a larger scale. Within this primary border, slimmer alternating borders featuring simpler floral designs and intricate leafy patterns add to the layered complexity and framing of the rug's overall design.

Symmetry is a key characteristic of this rug, with the patterns on either side of the central axis mirroring each other. This balance contributes to an orderly and visually appealing presentation, a common trait in traditional Kashan rug designs.

Antique Kashan carpets, renowned for their meticulous artistry and high level of detail, continue to be highly regarded in the realm of Persian rugs. This particular piece, from around 1940, stands as a testament to the enduring quality and appeal of Kashan's weaving traditions.
