A finely flat-weave antique Azeri Shadda rug from the Azeri tribe in the southern Caucasus, distinguished by a tartan-like composition of polychrome vertical bands alternated with lozenges. This type of effect is achieved through a complex plain weave technique characteristic of this group called Shadda. These weavings were employed as covers or hangings as they are typically in excellent condition, often (like in this example) with rings tied to the back, suggesting their use as tapestries. The superior quality of the natural dyes confers a level of ‘best of type’ to this weaving.
