Three of the earliest ( 1897-1905 ) datable Tibetan rugs are in the Royal Museum of Scotland in Edinburgh and one ( 1885 ) in the Smithsonian Institution in Washington D.C. These four rugs and others that can be dated from the 19th. century , show simple medallion designs. Like the one here in ref.7395/6 ER 699, they have a low count of knots, few colours, are all wool and of smaller sizes. The medallion pattern derive both from Central Asia, particularly from East Turkestan, and from silk brocades and porcelain from China.
