Mogao Caves in the context of "Robert Gauthiot"

Emperor Wu of Han (156 – 29 March 87 BC), personal name Liu Che and courtesy name Tong, was the seventh emperor of the Han dynasty from 141 to 87 BC. His reign lasted 54 years – a record not broken until the reign of the Kangxi Emperor more than 1,800 years later – and remains the record for ethnic Han emperors. His reign resulted in a vast expansion of geopolitical influence for the Chinese civilization, and the development of a strong centralized state via governmental policies, economical reorganization and promotion of a hybrid Legalist–Confucian doctrine. In the field of historical social and cultural studies, Emperor Wu is known for his religious innovations and patronage of the poetic and musical arts, including the development of the Imperial Music Bureau into a prestigious entity. It was also during his reign that cultural contact with western Eurasia was greatly increased, directly and indirectly.

During his reign, Emperor Wu led the Han dynasty through its greatest territorial expansion. At its height, the Empire's borders spanned from the Fergana Valley in the west, to northern Korea in the east, and to northern Vietnam in the south. Emperor Wu successfully repelled the nomadic Xiongnu from systematically raiding northern China, and dispatched his envoy Zhang Qian into the Western Regions in 139 BC to seek an alliance with the Greater Yuezhi and Kangju, which resulted in further diplomatic missions to Central Asia. Although historical records do not describe him as being aware of Buddhism, emphasizing rather his interest in shamanism, the cultural exchanges that occurred as a consequence of these embassies suggest that he received Buddhist statues from Central Asia, as depicted in the murals found in the Mogao Caves.

The Dunhuang map or Dunhuang Star map is among the earliest known graphical depictions of the night sky in ancient Chinese astronomy, dating to the Tang dynasty (618–907). Prior to the discovery of this map, much of the star-related information recorded in early Chinese texts had been subject to speculations. The map provides visual corroboration of those textual records and forms part of a scroll that includes a series of illustrations found among the Dunhuang manuscripts. It is currently regarded as the world's oldest known complete star atlas.

The manuscript containing the star map was discovered in the early 20th century in the Mogao Caves and was taken along with hundreds of other manuscripts during a British expedition to Dunhuang. The scroll containing the Dunhuang map is currently held in the British Library.

Dunhuang (or DunHuang, listen) is a county-level city in northwestern Gansu Province, Western China. According to the 2010 Chinese census, the city has a population of 186,027, though 2019 estimates put the city's population at about 191,800. Sachu (Dunhuang) was a major stop on the ancient Silk Road and is best known for the nearby Mogao Caves.

Dunhuang is situated in an oasis containing Crescent Lake and Mingsha Shan (鳴沙山, meaning "Singing-Sand Mountain"), named after the sound of the wind whipping off the dunes, the singing sand phenomenon. Dunhuang commands a strategic position at the crossroads of the ancient Southern Silk Route and the main road leading from India via Lhasa to Mongolia and southern Siberia, and also controls the entrance to the narrow Hexi Corridor, which leads straight to the heart of the north Chinese plains and the ancient capitals of Chang'an (today known as Xi'an) and Luoyang.

Irk Bitig or Irq Bitig (Old Turkic: 𐰃𐰺𐰴 𐰋𐰃𐱅𐰃𐰏‎), known as the Book of Omens or Book of Divination in English, is a 9th-century manuscript book on divination that was discovered in the "Library Cave" of the Mogao Caves in Dunhuang, China, by Aurel Stein in 1907, and is now in the collection of the British Library in London, England. The book is written in Old Turkic using the Old Turkic script (also known as "Orkhon" or "Turkic runes"); it is the only known complete manuscript text written in the Old Turkic script. It is also an important source for early Turkic mythology.

The Dunhuang manuscripts are a large and varied collection of religious and secular texts, consisting mainly of handwritten manuscripts on materials such as hemp, silk, and paper, along with some woodblock-printed items. Composed in a range of languages including Chinese, Tibetan and others, these manuscripts were discovered in 1900 at the Mogao Caves near Sachu in Dunhuang, Gansu Province, China, by the itinerant Daoist monk Wang Yuanlu. After taking over the caves, Wang sold the manuscripts to Aurel Stein and Paul Pelliot for a modest sum. Knowing the philological value of the Dunhuang manuscripts, Stein and Pelliot bought them from Wang and took them from China to Europe.

Most of the manuscripts originate from a cache of documents produced between the late 4th and early 11th centuries. These were sealed in what is now known as the Library Cave (Cave 17) sometime in the early 11th century. The site at Sachu (modern-day Dunhuang) was an important regional centre for manuscript production during this period and had also served as an official printing office during the 8th and 9th centuries when the area was under Tibetan rule and formed part of the Silk Road network.

The Western Thousand Buddha Caves (Chinese: 西千佛洞; pinyin: Xī Qiānfó Dòng) is a Buddhist cave temple site in Dunhuang, Gansu Province, China. The site is located approximately 35 km southwest of the urban centre and about the same distance from the Yangguan Pass; the area served as a staging post for travellers on the Silk Road. It is the western counterpart of the Mogao Caves, also known as the "Caves of the Thousand Buddhas" after the founding monk Yuezun's vision in 366 of "golden radiance in the form of a thousand Buddhas". The caves were excavated from the cliff that runs along the north bank of the Dang River. A number have been lost to floods and collapse; some forty are still extant. Twenty-two decorated caves house 34 polychrome statues and 800 m of wall paintings, dating from the Northern Wei to the late-Yuan and early-Ming dynasties (sixth to fourteenth centuries). The site was included within the 1961 designation of the Mogao Caves as a Major National Historical and Cultural Site.

The Eastern Thousand Buddha Caves (simplified Chinese: 东千佛洞; traditional Chinese: 東千佛洞; pinyin: Dōng Qiānfó Dòng) is a series of rock cut Buddhist caves in Guazhou County, Gansu, northwest China. Of the twenty-three caves excavated from the conglomerate rock, eight have murals and sculptures dating from the Western Xia and Yuan dynasty; many of the statues were reworked during the Qing dynasty. The caves extend in two tiers along the cliffs that flank both sides of a now dry river gorge, fourteen on the west bank (five with decoration) and nine on the east (three with decoration). Together with the Mogao Caves, Western Thousand Buddha Caves, Yulin Caves, and Five Temple Caves, the Eastern Thousand Buddha Caves is one of the five grotto sites in the vicinity of Dunhuang managed by the Dunhuang Academy.

The Yulin Caves (Chinese: 榆林窟; pinyin: Yulin kū) is a Buddhist cave temple site in Guazhou County, Gansu Province, China. The site is located some 100 km (62 mi) east of the oasis town of Dunhuang and the Mogao Caves. It takes its name from the elm trees lining the Yulin River, which flows through the site and separates the two cliffs from which the caves have been excavated. The forty-two caves house some 250 polychrome statues and 4,200 m (45,000 sq ft) of wall paintings, dating from the Tang dynasty to the Yuan dynasty (seventh to fourteenth centuries). The site was among the first to be designated for protection in 1961 as a Major National Historical and Cultural Site. In 2008 the Yulin Grottoes were submitted for future inscription on the UNESCO World Heritage List as part of the Chinese Section of the Silk Road.
