Books like irk bitig

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 only extant version of the Irk Bitig is a manuscript from the Dunhuang Library Cave that is now held at the British Library (shelfmark Or.8212/161).
