Tribal dozar, Noberan/Kerder design, 4.5 x 6.7. Late 19th Century. a varient of the so called “lightning” design. This piece is unusual having been woven on lovely dark brown wool foundation. The Mazlaghan area of western Persia is inhabited by Shahsavan (known for using dark brown wool in foundations). In any case, the rug is probably a nomadic tribal piece rather than a village one. Fine natural colors and even dense pile.
