result of the artistic activity and expansion of the Tang dynasty. The civilization of Kucha, with the whole Tarim Basin from Turfan to Khotan, fell to the Chinese punitive invasion of 648 CE, putting an end to the Indo-Iranian styles of Kucha. Ashina She'er, the East Turkic general leading the Tang dynasty expeditionary corps, ordered the execution of eleven thousand Kuchean inhabitants by decapitation. It was recorded that "he destroyed five great towns and with them many myriads of men and women... the lands of the west were seized with terror." Two caves at Kizil have art of the Tang period: cave 43 and cave 229. In nearby Kumtura and in Turfan, Chinese styles now prevailed. In 670 CE, the Tibetan Empire conquered most of the Tarim Basin, including Khotan, Kucha, Karashahr and Kashgar, which they kept until the Chinese took back the control of the area in 692. In 753 CE, the northern part of the Tarim Basin was taken over by the Turks of the Uyghur Khaganate, based in Turfan. A new Tibetan conquest took place in 790 CE. By 900 CE, the area was under Muslim domination. Texts and inscriptions Love poem Most of the texts known from the Tocharians are religious, except for one known love poem in Tocharian B, found in Kizil and dated circa 600 CE (manuscript B-496): "Kyzil library" The Kyzil library had some of "the oldest copies of the Indian theatre known today" written in Sanskrit or in Tokharian B: these Indian plays, called Nāṭaka in Sanskrit literature, alternate prose and verse, music and pantomime, and also provide scenic indications so that a single performer can enact a complete play by changing attitudes and voices. These plays are at the origin of the "chantefables" or Chinese "transformation texts" called Bianwen. 13th century Tibetan document about Kizil Albert Grünwedel, one of the German discovers of the Kizil Caves, found in Saint-Peterburg a 13th-century Tibetan text related to Kucha and the Kizil Caves, including a map, which describes the caves from the perspective of Tantric Buddhism. According to the Tibetan text, the paintings in some of the caves were commissioned by a Tokharian (Thogar) king called "Mendre" (probably Māndhātṛ) with the advice of Anandavarman, a high-ranking monk. The king ordered an Indian artist, Naravahanadatta, and a Syrian artist, Priyaratna, with their disciples to paint the caves. The neighbouring Khotanese kings Vijayavardhana and Murlimin also
