The asymmetrical knot of hand-knotted rugs, the counterpart of the symmetrical Turkish (Ghiordes) knot. The weaver wraps the yarn around one warp thread and passes it under the neighboring one, usually working by hand without a hook. On the back of the rug the knots look staggered or diagonal rather than like tidy squares, and the pile feels softer; the knot permits finer detail and higher knot density. In Iran, a rule of thumb ties it to the central, eastern, and southern rugs (Kashan, Isfahan, Nain, Kerman), while the northwest and west favor the Turkish knot, though exceptions exist. Fine curvilinear florals are often credited to it, but Turkish-knot rugs can be just as intricate.
Popular, durable Persian city rugs from Sarouk, a town in central Iran about 50 km (31 miles) north of Arak, prominent from the 19th century and exported to Europe and America. A cotton foundation carries a medium-to-thick wool pile, at times with silk highlights, usually tied with the Persian knot (some older pieces use the Turkish knot) at medium-to-high density of up to about 320 knots per square inch (roughly 50 per cm²). Floral, medallion and allover designs, with some Herati, boteh and pictorial patterns, appear on beige, ivory, cream, navy or red fields, the red leaning toward orange or rust, usually with a thin secondary border. American Sarouks, woven mainly in the 1920s and 1930s, adapted designs and colors to U.S. taste, and many were re-dyed to a preferred rose red.
Finely woven small-to-medium rugs and runners from the Kurdish weaving villages around Senneh (modern Sanandaj) in western Iran, known for meticulous, thin, tight single-weft construction on a cotton foundation with a wool pile. Designs are mostly geometric medallions and allover patterns, with boteh and Herati also woven, in dark red, navy, and brown, sometimes beige, with yellow, red, light green, orange, and white accents. The city gives its name to the “Senneh knot”, another name for the asymmetrical Persian knot, yet its weavers actually use the symmetrical Turkish knot.
One of the two main knots of hand-knotted rugs, also called the symmetrical knot (the other being the asymmetrical Persian or Senneh knot). The yarn is looped around two adjacent warp threads with both ends emerging between them, so the back shows small, even, squarish knot heads; weavers often tie it with a hook. Named after the town of Ghiordes (modern Gördes) in Turkey, it is typical of Turkey, the Caucasus and northwestern Iran (Tabriz, Bijar, Heriz, village Hamadan), where Seljuk Turks are said to have introduced it, and gives a durable, precise pile. The Persian knot is often credited with finer detail, yet knot type is a tendency, not a limit: Tabriz rugs woven with the Turkish knot reach about 500 knots per square inch (roughly 78 per cm²).
