History of the Armenians

...Procopius took the affairs of our King Abgar, which he describes in a style mixed with legends, according to the example of the scribe. Some have thought that he is also the anonymous historian who, as Khorenatsi Moses of Chorene, the "father of Armenian history" says, stuttered in a formless manner regarding Hayk. Second, it is suspect that these four books may be incomplete at the end. For at the beginning of the sixth book, as we said, the historian promises to provide information about himself at the end of all the histories. And until reaching the end, in the sixth chapter, he speaks only incidentally of a certain Bishop P'awstos; he provides no information about himself at the end of the book. One may believe that the end of the histories, where he would have written truthfully about himself, met with the same misfortune as the poems of our "father of poets" referring to Moses of Chorene about himself and about Sahak Bagratuni—which are marked in the chapter lists but appear nowhere in the book. Now, if these doubts are not groundless, and if with the help of time the missing parts are filled, perhaps it will then be possible for us to confirm more accurately who this historian was. For now, we have nothing more to say than this. As for the disagreement of his chronology with the most reliable of our historians, it is not for us to dispute here.

The current printed edition was made by comparing five examples, of which one is ancient and undated.
