The material used for the rug, wool on cotton, indicates that it was constructed with hardwearing natural fibers, which have been carefully dyed to achieve a vibrant range of colors. The overall size of the rug is substantial and impressive, specifically 10 feet by 14 feet, which makes it suitable for large spaces.

Continuing with the analysis of the rug, the dominant color is medium blue, a shade that adds depth and richness. This hue rules the majority of the rug’s surface and sets the tone for the overall color scheme. A blue tone of this intensity brings a sense of calm, stability, and sophistication, and mixes well with other how this hue pairs with the other warm and cool colors in the design.

Speaking more specifically about the rug’s design, it belongs to the 'Heriz' style, which belongs to a tradition of Persian carpet creation. Heriz rugs are known for their striking geometric patterns, and this is translated here in the rug's large stylized medallion and the symmetrical elements surrounding this central icon. The overall pattern is dominant but not overwhelming, with the symmetry adding balance.

It's also important to note its 'tribal' designation. This refers to the specific stylistic quirks common to rugs woven by tribal communities. These rugs are often characterized by their more vernacular, traditional design as opposed to the more formal designs of urban weavers. This rug clearly reflects this approach, as it features an assortment of ornaments and motifs that are typical of tribal rugs.

Finally, it's worth noting that this rug is defined as new. This means that it is probably a recent creation, and not an antique. However, even though it's new, the rug's design, craftsmanship, and material use are firmly rooted in the traditions of Persian and tribal rug-making.

In summary, this rug is a magnificent work of artistry and craftsmanship, offering a splendorous blend of traditional tribal and Heriz Persian rug styles. The rug features a medium blue background, a central medallion, and an assortment of motifs and ornaments, all rendered in wool on cotton by hand. With its compelling design and eye-catching colors, this rug makes a captivating heritage statement, even as contemporarily made piece.
