Analysis of information sources in references of the Wikipedia article "Codex Marianus" in English language version.
Codex Marianus, from the beginning of the eleventh century, was also copied in Macedonia and is kept in Moscow (two leaves are in Vienna)
Although one of them was found in the Monastery of the Holy Mother of God on Mount Athos (hence its name, Codex Marianus), both were written in Glagolitic either in Ohrid or in one of the monastic centers in the region.
The Codex Marianus (Mar) has 174 folia, containing the Gospel text from Mt 5:23 to John 21:7. Certain deviations from the theoretical norms indicate Macedonian influences, others possibly Serbian (if not northern Macedonian).
