The Old Turkic script (also Göktürk script, Orkhon script, Orkhon-Yenisey script; Turkish: Orhun Yazıtları, 鄂爾渾文字) is the alphabet used by the Göktürk from the 8th century to record the Old Turkic language. It was later used by the Uyghur Empire; a Yenisei variant is known from 9th-century Kyrgyz inscriptions, and it has likely cousins in the Talas Valley of Turkestan and the Old Hungarian script of the 10th century. The alphabet was usually written from right to left.
The script is named after the Orkhon Valley in Mongolia, where 8th century inscriptions were discovered in an 1889 expedition by Nikolay Yadrintsev. These Orkhon inscriptions were published by Vasily Radlov and deciphered by the Danish philologist Vilhelm Thomsen in 1893.
The script is very similar to that on monuments left by Tu-jue (突厥 pinyin tú jué) in China during the Tang Dynasty. Because of similarities to the angular shapes of the runic alphabet, the letters of the Orkhon script have been referred to as "Turkic runes" or described as "runiform". This similarity is superficial, however, since all alphabetic scripts used for incision in hard surfaces show this tendency (see Old Italic alphabets for other examples).
Mainstream opinion derives the Orkhon script from variants of the Aramaic alphabet, in particular via the Pahlavi and Sogdian alphabets, as suggested by V.Thomsen, or possibly via Karosthi (cf., Issyk inscription).
Alternative possibilities include derivation from tamgas, suggested by W. Thomsen in 1893, from the Chinese script. Turkish inscriptions dated earlier than the Orkhon inscriptions used about 150 symbols, which may suggest tamgas at first imitating the Chinese script and then gradually refined into an alphabet.
The Danish hypothesis connects the script to the reports of Chinese account, from a 2nd century BC Chinese Yan renegade and dignitary named Zhonghang Yue (中行说) who
Kazakh turkologist A. S. Amanzholov proposes that the script may derive directly from the Phoenician alphabet, or even "ascends to the most ancient common source of alphabetic writing [...] of the 3rd - 2nd millennia BC"..
The Orkhon monuments are the oldest known examples of Turkic writings; they are inscribed on obelisks and have been dated to 720 (for the obelisk relating to Tonyukuk), to 732 (for that relating to Kültigin), and to 735 (for that relating to Bilge Kağan). They are carved in a script used also for inscriptions found in Mongolia, Siberia, and Eastern Turkistan and called by Thomsen "Turkish runes". They relate in epic language the legendary origins of the Turks, the golden age of their history, their subjugation by the Chinese, and their liberation by Bilge. The polished style of the writings suggests considerable earlier development of the Turkish language.
These alphabets are divided into four groups by Kyzlasov (1994)
The Asiatic group is further divided into three related alphabets:
The Eurasiatic group is further divided into five related alphabets:
A number of alphabets are not completed, due to the limitations of the extant inscriptions. Great help in the studies of the Türkic scripts was received from Türkic-Chinese bi-lingual inscriptions, contemporaneous Türkic inscriptions in Greek alphabet, literal translation into Slavic language, and paper fragments with Türkic cursive writing on Türkic religion, Manichaeism, Buddhist and legal subjects of the 8-10th centuries AD found in Uyghurstan/Eastern Turkestan.
During the last two centuries the number of specialists knowledgeable in the Türkic scripts never exceeded low single digits. The last quarter of the 20th century brought about most of the paleographical and textual discoveries.
