Old Slavic vs Church Slavonic (How it sounded)

Hello, everyone. Due to popular request, in this video we shall compare the readings of the same texts written both in Old Slavic and in Church Slavonic.
These Old Slavic texts all come from Codex Zographensis. The manuscript was found in the Bulgarian Zograf Monastery on Mount Athos in 1843 by the Croatian writer and diplomat Antun Mihanović. Codex's existence was however made known to public by Izmail Sreznevsky who published some parts of it in 1856. In 1860 monks from the Zograf monastery donated the Codex to Russian emperor Alexander II who donated it to Russian National Library, where the Codex is being kept today. The first to describe the codex was Viktor I. Grigorovič in 1877, and two years later the Glagolitic part of the codex was published by Slavist Vatroslav Jagić in Berlin as Quattuor evangeliorum codex glagoliticus olim Zographensis nunc Petropolitanus, completely transcribed in Cyrillic, with introduction and extensive philological commentary in Latin. Jagić's edition has been reprinted as a facsimile edition in Graz in 1954.
Basically, we are going to read the texts which are literally 1000 years old.
