The steles were erected by the
Göktürks in the early 8th century. They commemorate the brothers
Bilge Qaghan (683–734) and
Kul Tigin (684–731), one a politician and the other a military commander. Both were descendants of
Ilterish Qaghan of the
Second Turkic Khaganate, which was a prominent Turkic nomadic society during the
Tang dynasty. The Göktürks have left artifacts and installations all over their realm, from
Manchuria to the
Black Sea, but only in modern-day Mongolia have any memorials to kings and other aristocrats been found. The ones in Khöshöö Tsaidam consist of tablets with inscriptions in
Chinese and
Old Turkic characters. Both monuments are stone slabs originally erected on carved
stone turtles within walled enclosures. Bilge Qaghan's stone shows a carved
ibex (the emblem of Göktürk qaghans) and a twisted dragon. In both enclosings, evidence of altars and carved depictions of human couples were found, possibly depicting the respective honorary and his spouse. The
Old Turkic inscriptions on these monuments were written by
Yollıg Tigin, a son of Bilge Qaghan. These inscriptions, together with the
Tonyukuk inscriptions, are the oldest extant attestation of that language. The inscriptions show the sacred importance of the region, as evidenced by the statement, "If you stay in the land of the Ötüken, and send caravans from there, you will have no trouble. If you stay at the Ötüken Mountains, you will live forever dominating the tribes!". == Content of the inscriptions ==
