Új liturgikus szövegkiadás-sorozat indult Monumenta Ritualia Hungarica címen. A sorozat célja a középkori magyar liturgikus hagyomány fönnmaradt emlékeinek megjelentetése. Első kötete az 1484-es, először kinyomtatott Esztergomi misekönyv (Missale Strigoniense 1484), második kötete egy, az esztergomi rítust szabályozó normatív szöveg, az 1493 és 1520 között hat ismert kiadást látott Esztergomi ordinárius (Ordinarius Strigoniensis) kritikai kiadása. A reprezentatív kiállítású köteteket terjedelmes és alapos tanulmány vezeti be, és kiemelkedően részletes mutatók zárják. Monumenta Ritualia Hungarica (MRH) The Monumenta Ritualia Hungarica (MRH), as the sub-series of the Bibliotheca Scriptorum Medii Recentisque Aevorum (BSMRAe), is a philologically accurate critical edition of the Hungarian liturgical sources and of the texts pertaining to the ritual of the wider Latin ecclesiastical tradition from the medieval period (before the Tridentine reforms). The MRH is in the care of the liturgical workshop established under the auspices of the Latin Department of the Faculty of Humanities of Loránd Eötvös University (Budapest). The most representative texts pertaining to the principal areas of the liturgy, namely, to the Divine Office, the Mass, the administration of sacraments and sacramentals, and the normative texts regulating the liturgical practice and life of the medieval Church will be published in their best versions. The larger sources (especially the Breviary) will be published in several volumes. In approaching the texts from a literary point of view, volumes of collections will be prepared according to the individual genres, especially a new critical edition of Hungarian liturgical poetry. The most important and most prevalent genres of the Hungarian Middle–Ages will thus provide firsthand information about the most characteristic and until now very much neglected area of the life and activity of the country’s medieval clerks. The now rapidly developing international study of the liturgy will, it is to be hoped, extend also to the heritage of the Carpathian Basin, which has heretofore been considered peripheral, not because it was insignificant but because it has not received sufficient scholarly attention. The present volume is a critical edition of the 1484 Missal of Esztergom, the most prestigious archiepiscopal see of Hungary. The printing of the Missale Strigoniense 1484 took place in the 2266 th year of King Matthias’ reign, and was finished on 31 August 1484, in Nuremberg, at Anton Koburger’s workshop. The manuscript of which the 1484 Missal could well be a textually faithful copy must have been a representative book of the Esztergom Use. Thus the present edition of an incunabulum of great significance in itself, could also become the foundation of comparative studies; all the differences in the other–both anterior and posterior–sources will be measured against this volume. The basis for the present edition is the copy Inc. 177 of the 1484 Missal from the Collection of Early Books (Régi Nyomtatványok Tára) of the National Széchényi Library (Budapest). The Missale Strigoniense 1484 is edited and introduced by Balázs Déri, head of the Latin Department of the Faculty of Humanities of Loránd Eötvös University (Budapest), classical and medieval Latin philologist and musicologist.
