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. 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. During the second half of the Middle–Ages, the Ordinal was the most important directive text that regulated liturgical practice. One of the few surviving examples of this from Hungary is the Ordinarius Strigoniensis (Esztergom Ordinal), which was first printed between 1493 and 1496, but which was rooted in a considerable pre-existing written tradition–as may be assumed by the parallels suggested in many related texts. An immediate ancestor of this printed Ordinal underwent a process of significant modification–possibly to prepare for its first printed edition–but these editorial efforts did not represent a terminus a quo; rather they represented an intermediary phase which transmitted the peculiarities of a hand-written culture to a printed one. This process was characterised both by the conservation of some elements and the abolition of others thought to be obsolete for this particular purpose. The present volume is based on all the six known editions of the book printed in Nuremberg, Venice and Lyon until 1520. The text is edited and introduced by liturgical historian and Latin philologist, Miklós István Földváry (1978), adjutant professor of the Latin Department of the Faculty of Humanities at Loránd Eötvös University and member of the Department for Sacred Music at the Ferenc Liszt Academy of Music (Budapest). He is one of the leading personalities for the reinvigoration of the Roman Rite and its Esztergom Use in Hungary.
