Where did the Thangka Originate?
The origin of the Thangka is not easy to trace. It would require us to go back in time, back to the Neolithic age in the Tibetan Plateau. The Thangka could be traced back to the Mogao caves along the silk road. Inside these caves, the earliest surviving paintings of Tibetan origin were found. These Tibetan paintings were set on the walls of the caves, though some of them were set on cloth.
From these early forms of Tibetan paintings evolved the traditional scroll paintings, which was later perfected during the Tubo Dynasty. The Tubo Dynasty was a period of powerful rulers in Tibetan History. This Dynasty started when a great Tibetan ruler by the name of Songtsan Gambo united the 10 separate tribes of Tibet during China's Tang Dynasty (618-907).
Based on an old legend, however, Songtsan Gambo, a Tubo King, started the tradition of the Thangka. Prompted by divine guidance and using the crimson blood that was oozing down his nose, he began to paint Bailamu. Thus, the first Thangka was created. Legend also said that the Living Buddha hid the first Thangka within the abdomen of the statue of Bailamu.
