Their rugs are often grouped with those of the Baluch, a tribe who inhabit the same area but who have different ethnic roots. Descended from east Persian carpets of the Safavid period, the design of this classic Timuri example consists of a central tree of life with alternating pairs of hexagonal medallions geometricized palmettes. Smaller medallions and floral motifs are interspersed throughout. Although the colors in Timuri carpets are typically somewhat limited in number, the weavers use them to great effect. Here, they have created variety and drama by reversing the color placement in each pair of opposing medallions and palmettes and by setting the design against a deep blue field. The use of dyed silk in the small diamond elements adds further variety to the palette. Carpets of this quality demonstrate the ability of tribal weavers to adapt the sophisticated, curvilinear designs of urban carpets to their own vigorous aesthetic.
