The antique Persian rug in question is a Lilihan piece crafted in the 1920s. Originating from Iran, this rug exemplifies tribal style and is noted for its sophisticated design work. The primary background of the rug is a rich navy color, while the border contrasts strikingly in ivory. The predominant color of the rug is blue, adding a layer of depth and visual interest. The materials used in its construction include wool for the pile and cotton for the foundation, a common choice for rugs of this type due to the durability and comfort provided by this combination.

Lilihan rugs are traditionally made by Armenian artisans in Iran, and the name 'Lilihan' specifically denotes the region known for its expertise in this form of textile craftsmanship. These carpets are celebrated for their intricate design elements, which often blend curvilinear lattices and floral motifs with geometric patterns. The rug's structure typically features a single weft, contributing to its coarse yet tightly woven form. This particular weaving technique enhances the rug’s strength and ensures long-lasting durability. Symmetrical knots and the Hamedan weave further underscore the quality and toughness of these rugs.

The central medallion design characteristic of this rug includes large, repeated medallions running down its centerline. Each medallion alternates in background color between cream and blue, creating a visually dynamic contrast. Detailed with floral or tree-like motifs, these medallions incorporate multiple colors such as red, green, white, and blue, lending a rhythmic pattern to the overall design.

The deep navy background sets the stage for these medallions, while smaller surrounding floral motifs are rendered in reds, whites, greens, and blues. The rug is framed by multiple cascading borders. The outermost border features a predominantly red background with intricate floral patterns, while a secondary outer border in blue displays additional floral and geometric designs. These borders are accented with smaller details in white, yellow, and blue, adding layers of complexity and visual appeal.

The combination of high-quality materials, expert craftsmanship, and intricate design elements ensures that this rug is not only a functional item but also a piece of art that reflects the rich weaving traditions of the Lilihan region.
