Made in the area of Gendje in the south-western Caucasus around 1870, this charming little prayer-rug with its very subtlety woven prayer-niche, contains a field of diagonal bands with small symbols often found in the Caucasus and amongst the Shahsevan nomads. The main ivory border is powerfully drawn and frames the field. In very good overall condition, this is a highly collectible and rare example of this area.
