In this book Ildik Bellr-Hann presents a transcription translation and analysis of the Tarikh-i Khata''i or the History of Cathay. Written in a little-known Turkic language referred to by scholars as Trk ''Acmi the Tarikh-i Khata''i serves as an excellent source for linguistic study. Bellr-Hann expertly dissects the language of this manuscript in order to argue that its linguistic features represent a predecessor of modern Azerbaijani Turkic. Beyond the extensive linguistic analysis Bellr-Hann also provides the reader with succinct historiography of the manuscript. This work is an essential source for any reader interested in Turkic and Persian languages and history.
