Orhon inscriptions

Orhon (or Orkhon) inscriptions are the oldest known Turkic writings, which were erected near the Orhon river (between 732-735 AD) in honour of two Kokturk princes Kul and Bilge. They have been carved on two monuments by old Turkic runes (see Old Turkic alphabet), which were deciphered by the Danish philologist Vilhelm Thomsen in 1893.
