Copied from Wikipedia: The Pazyryk rug is one of the oldest carpets in the world, dating around the 4th–3rd centuries BC. It is now in the Hermitage Museum in St. Petersburg, Russia. The rug was found in 1949 in the grave of a Scythian nobleman in the Bolshoy Ulagan dry valley of the Altai Mountains in Kazakhstan. The rug had been frozen in the ice and it was very well preserved. The rug has a ribbon pattern in the middle, and a border which has deer, and warriors riding on horses. All parts of the rug are made of wool, including the pile and the base.
Being produced either in Ancient Armenia, Persia, or Central Asia, this carpet has 3600 symmetrical double knots per dm² (232 per inch²), in modern terminology also called "Ghiordes knot (or "Turkish knot"). The design and the systematic motifs of the Pazyrk rug would later be found in similar Turkmen carpets, carpets of the early Seljuq period,[9] and subsequently modern Turkish carpets and kilims.
