Articolul se axează asupra importanței vechilor manuscrise religioase româno-slave care, în general, sunt prea puțin cunoscute publicului. Ca exemplu ilustrativ ne va servi un manuscris transilvan din anul 1511 care la moment se află expus în Muzeul Mitropoliei Cluj. În rândurile de mai jos ne vom referi la două aspecte – istoriografia slavonismului cultural din Transilvania în secolul al XV-lea - începutul secolului al XVI-lea și caracteristicile Tetraevanghelului de la Cluj, copiat de preotul Mihail de la Bîrgău în anul 1511.

The paper is dedicated to a Slavonic manuscript from Transylvania, copied in 1511 in the village of Bîrgău. The text of the paper is divided in two parts. The first one is dedicated to the historiography of the issue of the Slavonic culture in Transylvania in XVth-XVIth centuries. In general it comprises two kinds of works - the studies which contain short references to the Old Romanian written culture from Transylvania and the repertories of Old Slavonic manuscripts in different funds from nowadays. The second part deals with the manuscript copied by the priest Mikhail from Bîrgău in 1511. The manuscript has Moldavian influences, that’s why in my opinion this priest should have studied at a monastery from Moldova (it could be Neamț). The purpose of this paper is to pay attention to the importance of the Old Slavonic-Romanian manuscripts and to the necessity of digitalizing at least their first pages and decorations.
