There are 77 rock-cut caves at the site. Most have rectangular spaces with rounded arch ceilings often divided into four sections, each with a mural of the Buddha. The effect is of entire ceiling covers with hundreds of Buddha murals. Some murals show a large Buddha surrounded by other figures, including Turks, Indians and Europeans. The quality of the murals vary with some being artistically naive while others are masterpieces of religious art. The murals that best represent the Bezeklik Thousand Buddha Caves are the large-sized murals, which were given the name the "Praṇidhi Scene", paintings depicting Sakyamuni’s "promise" or "praṇidhi" from his past life. Professor James A. Millward described the original Uyghurs as physically Mongoloid, giving as an example the images in Bezeklik at temple 9 of the Uyghur patrons, until they began to mix with the Tarim Basin's original Indo-EuropeanTocharian inhabitants. Buddhist Uyghurs created the Bezeklik murals. However, Peter B. Golden writes that the Uyghurs not only adopted the writing system and religious faiths of the Indo-European Sogdians, such as Manichaeism, Buddhism, and Christianity, but also looked to the Sogdians as "mentors" while gradually replacing them in their roles as Silk Road traders and purveyors of culture. Indeed, Sogdians wearing silk robes are seen in the praṇidhi scenes of Bezeklik murals, particularly Scene 6 from Temple 9 showing :File:BezeklikSogdianMerchants.jpg|Sogdian donors to the Buddha. The paintings of Bezeklik, while having a small amount of Indian influence, is primarily influenced by Chinese and Iranian styles, particularly Sasanian Persianlandscape painting. Albert von Le Coq was the first to study the murals and published his findings in 1913. He noted how in :File:Bezeklik caves, Pranidhi scene 14, temple 9.JPG|Scene 14 from Temple 9 one of the Caucasian-looking figures with green eyes, wearing a green fur-trimmed coat and presenting a bowl with what he assumed were bags of gold dust, wore a hat that he found reminiscent of the headgear of Sasanian Persian princes. The Buddhist Uyghurs of the Kingdom of Qocho and Turfan were converted to Islam by conquest during a ghazat at the hands of the Muslim Chagatai Khanate ruler Khizr Khoja. After being converted to Islam, the descendants of the previously Buddhist Uyghurs in Turfan failed to retain memory of their ancestral legacy and falsely believed that the "infidel Kalmuks" were the ones who built Buddhist monuments in their area. The murals at Bezeklik have suffered considerable damage. Many of the temples were damaged by local Muslim population whose religion proscribed figurative images of sentient beings; all statues were destroyed, some paintings defaced and others smeared with mud, the eyes and mouths were often gouged out due to the local belief that the figures may otherwise come to life at night. Michael Dillon considered Bezeklik's Thousand Buddha Caves are an example of the religiously motivated iconoclasm against depiction of religious and human figures. Pieces of murals were also broken off for use as fertilizer by the locals. During the late nineteen and early twentieth century, European and Japanese explorers found intact murals buried in sand, and many were removed and dispersed around the world. Some of the best preserved murals were removed by German explorer Albert von Le Coq and sent to Germany. Large pieces such as those showing Praṇidhi scene were permanently fixed to walls in the Museum of Ethnology in Berlin. During the Second World War they could not be removed for safekeeping, and were thus destroyed when the museum was caught in the bombing of Berlin by the Allies. Other pieces may now be found in various museums around the world, such as the Hermitage Museum in St. Petersburg, Tokyo National Museum in Japan, the British Museum in London, and the national museums of Korea and India. A digital recreation of the Bezeklik murals removed by explorers was shown in Japan.
