Vision of the prophet Isaiah of the last times

In the article reported is a newly discovered copy of “Vision of the prophet Isaiah of the last times” in the collection “Zlataya Matitza” (HCPK № F.312), from the 70s of the 15th century, collection of the Russian National Library in Saint Petersburg. It is mechanically attached to the text of the early Slavonic composition „Слово святого Григория изобретено в толцех о том, како первое погани съще языци кланялися идолом и требы им клали, то и ныне творят”. The last text is an instruction against the pagan rituals, which belongs to a very early epoch of the history of the Slavonic literatures and cultures. It is established that the historical-apocalyptic work “Vision of the prophet Isayah” according to the newly discovered copy is close to the earliest known copy – in the Dragol collection from the third quarter of the 13th century. The author analyzes the manuscript tradition of “Слово святого Григория изобретено в толцех”, defines the history and the specific of the work, and at the same time makes suggestions about the penetration of “Vision of the prophet Isaiah” in the Russian manuscripts. The text of the collection “Zlataya Matitza” is published with different readings by the rest of the copies, accompanied by an analysis of some important linguistic peculiarities.
