The art of Oriental Rug weaving is a craft that dates back 2500 years. The oldest hand-knotted pile rug was found in the Pazyryk Valley in Siberia. It had been preserved in solid ice since the 5th century BC, until it was discovered in the late 1940's. It measures approximately 6 feet square, and can be viewed in the Hermitage Museum in Leningrad. Presently, true Oriental Rugs are made in areas that include the Near East, Middle East, Far East, the Balkans, and Northern Africa. They are hand-woven with natural fibers consisting of a wool or silk pile.
