The office for the feast of the Dedicatio Ecclesiæ was used and transmitted mainly in the same form in the great majority of medieval liturgical codices. Within this general uniformity, however, the arrangement of the antiphons for the first Vespers varies from tradition to tradition. The present article examines the repertory of the Dedicatio in medieval Hungarian manuscripts, comparing it to the offices found both in other Middle European and in West Frankish sources. This comparative analysis made clear, that although the vesper antiphons in question were already included in the Codex Albensis (the earliest extant office manuscript from 12th-century Hungary) and can be found in almost all manuscripts from the medieval Hungarian archdiocese of Esztergom (Strigonium), they were rarely used in other Central European areas. These items may originate from the Rhineland, from within the region of Liège (Lüttich), what is confirmed by their occurrence in a 14th-century antiphoner from Aachen and in the Breviarium Præmonstratense. Furthermore, the five antiphons were probably not composed as a coherent sequence of chants. Although occasionally we come accross the individual pieces in sources of different time and place, their organization into cycles may be the result of later and secondary local initiations. The cycle might have been transferred to Hungary during the 11th century where it remained unchanged until the end of the Middle Ages.
