Ïrq bitig, the “Book of Omens”, is a literary work which has attracted the attention of many scholars. It is a work whose many cultural implications demand ever deeper levels of scholarly interpretation. Until recently, however, many questions concerning its content, and even its exact date and provenance, have remained somewhat obscure. Due to the brilliant investigations of J.R. Hamilton it has by now become clear that Ïrq bitig was completed on March 17, 930 AD in the Manichaean monastery of the Great Cloud (Taygüntan manystan, Chin. Dayuntang). Its author or compiler was a junior cleric (kiĉig di(n)tar) who dedicated this work to his elder brother, the military commander It Aĉuq.
