The Ghiordes knot or Turkish knot is one of the two most-used knots employed in knotted-pile carpets. (The other is the Senneh knot, typical of Persian carpets.) In the Ghiordes knot, the colored weft yarn passes over the two warp yarns, and is pulled through between them and then cut to form the pile. The Turkish knot has a symmetrical structure. The Ghiordes knot is the knot used in the oldest surviving pile carpets, the fragments found in Pazyrykkurgan burial mounds, in the Altai of Central Asia.
