Bust of Kul Tigin

The Bust of Kul Tigin is an 8th-century marble bust thought to represent Kul Tigin, a Turkic general and prince of the Second Turkic Khaganate. The head was probably part of a seated figure, whose torso was found in the same building at the Complex of Kul Tigin in Khöshöö-Tsaidam, Mongolia. Differently from other artifacts found at this site and the neighboring one, such as a golden diadem, the Bilge Khan Crown, this stone sculpture and a number of paintings now lost were likely the work of Tang Chinese artisans, as reported in the Book of Tang. The fact it was sculpted by a Chinese artisan could explain the origin of the sculpture's hat. It is also possible that the hat, which was also in use among Eastern Turks, was reproduced by the Chinese artist from the actual headgear of the deceased Kul Tigin. The eagle depicted on the hat is similar to the Golden Crown of Bilge Khan, produced by a local artisan. The Czech archeologist Lumír Jisl who found the head, described the animal on the Bust of Kul Tigin's hat first as a heraldic eagle, later opting for a falcon, which the Turks associated with death. It could also represent the phoenix, often depicted by Eastern Turks with similarly spread wings.

Overview
The statue was found at the excavations carried out at Orkhon. It was found at the complex of Kul Tigin (KhöshööTsaidam-2), located about 1 km north of the Burial Complex of Bilge Khan. The site is attributed to Kul Tigin due to the monument which was discovered here in the 1880s, the Orkhon inscriptions, identifying the place as a memorial to Bilge Khan's brother Kul Tigin. Successive excavations revealed a 10 x building in the middle of the complex. It had a central room and a corridor around it. Inside of the former there was the severed head on one side, and two marble torsos of seated figures on the other. Their heads were missing. The so-called Bust of Kul Tigin, found by the Czech archeologist Lumír Jisl is thought to have once belonged to one of the torsos.

While metalwork such as the golden diadem, found at the neighboring site, was the work of local, Central Asian artisans, this site's mural paintings, of which only a few fragments survive, and sculptures in the "ancestral temple" (i.e. Kul Tigin Complex's barq) were likely the work of Chinese artisans. This is suggested in the Old Book of Tang, and confirmed in the Orkhon inscriptions, where Bilgai Khan states that he asked for Chinese artisans to be sent to him, and ordered them to decorate the memorial to his brother.

The "bird tiara" of the sculpture, featuring an eagle, might be an import from Tang China. However, it also resembles the diadem found at the neighboring site of Bilge Khan, which was likely the work of a Central Asian metalsmith.

The eagle depicted on the hat is similar to the Golden Crown of Bilge Khan, likely produced by a local, Central Asian artisan. Lumír Jisl described the animal on the Bust of Kul Tigin's hat first as a heraldic eagle, later opting for a falcon, a symbol of death. The Turks associated the eagle/falcon with death. It could also represent the phoenix, often depicted by Eastern Turks with similarly spread wings. Stark reports that a wooden sculpture of Vaiśravaṇa from ancient Kyoto, said to have been brought from China in AD 800, has a similar hat with the depiction of a bird. A hat called heguan (he-bird hat) was used by Chinese military officials. Rather than ascribing a Buddhist origin to the hat, Stark says that the statue in Kyoto has a military connection, rather than religious. Stark concludes by saying that the "bird-tiara" was in use among the Eastern Turks as a symbol of supreme military authority, and that its origins should be ultimately traced back to the Chinese "pheasant hat", used as a symbol of high rank by Chinese military officials. Indeed, Turkic culture received influences not only from the Chinese, but also from Iranian, Indian, Byzantine civilisations, combining these elements in their own distinct culture.

As for the crown, analogous to the bird's depiction on the hat, no "direct analogies" with this kind of crown have been found in the early Turkic steppes. However, similar examples have been found in Sogdia and in Eastern Turkestan. Stark speculates that the idea behind this type of crown may have a "distant Indian origin".

In contemporary culture
The Bust of Kul Tigin is depicted on a KZT 1,000 tenge banknote, issued by the Kazakh government. The issue of the commemorative banknote was confirmed by the Kazakh government on December 12, 2013. The banknote was dedicated to the Second Turkic Khaganate on both sides, with the Silver Deer on one side, and the Bust of Kul Tigin on the other. About 10 million banknotes were put in circulation by the National Bank of Kazakhstan.
