These two fragments of the Archdiocesan Theological Seminary (Nadbiskupsko bogoslovno sjemenište), Zagreb, under the shelfmark 25626 belong to the second volume of Breviarium notatum Strigoniense (abbr. BNS II), a musically notated breviary of Esztergom from the second half of the 13th century. The fragment on the front cover reveals some sections of the Lauds, the Short Hours, and the second Vespers of the Common of the Apostles. The musical notation was made by the secondary notator of BNS II. The fragment on the back cover shows the Short Hours and the homily (by St Jerome) of the Common of One Martyr.
The codex itself survived in an entirely fragmented state: most of the corpus (258 fragments) is on the covers of 15th—17th century printed books of the Metropolitanska knjižnica Zagrebačke nadbiskupije (Metropolitan Library, Zagreb); further four fragments are among the detached fragments of the ELTE University Library and Archive, Budapest, and two fragments are in the possession of the Franciscans at Zagreb. (For the latter group’s detailed description see fragments F328a, F328b, F 1104.) At the end of the 17th century – among other manuscripts – the codex was used as raw material by the bookbinder of the Zagreb Chapter after bishop Aleksandar Mikulić (1688—1694) ordered the printed books of the Chapter to be bound uniformly.
