Codex Zographensis

The Codex Zographensis (or Tetraevangelium Zographense; scholarly abbreviation Zo) is an illuminated Old Church Slavonic canon manuscript.

The codex's importance was announced by the Russian historian and folklorist Victor Grigorovich who visited the monastery one year later and who is regarded as the founder of Slavonic studies in Russia.

Other scholars who have extensively studied the language of Codex Zographensis were Josef Kurz, Leszek Moszyński and the librarian Vyacheslav Zagrebin who was responsible for its restoration during the 1990s.

During January 2016, monks of the Zograf monastery visited Saint Petersburg in order to report about a digitisation project of the manuscript which intended to make it available to the public.

The first few ones have not been preserved, and thus it begins with Matthew 3:11 and ends with John, with Mt 16:20-24:20 being later insertion in Old Church Slavonic Grammar.

Along with the slightly older Codex Marianus it is an important document for its use of the round Glagolitic script, the oldest recorded Slavic alphabet.
