Researchers believe that the origin of Tibetan Carpet weaving was most likely evolved indigenously and in isolation, dating as far back as 7th Century A. D, as evidenced by excavations done around the Silk Road. This explains the unique weaving technique and physical structure of Tibetan Carpet weaving, distinct from that of neighboring China and India, as well as from other extant weaving traditions worldwide. Specifically, it is the use of archaic vertical loom and the peculiar archaic knotting technique.
