For the history of the corpus of the codex, and for its liturgical and musical characteristics see the description of fragment F 1102 (Zágráb/Zagreb, Knjižnica franjevačkog samostana (Kaptol), cover of B-III-191).
This fragment, similarly to the cover of the book under the shelfmark B-III-191 is from the Vespers leaves of the Franciscan psalter illuminated in Buda at the turn of the 15th and 16th centuries. It contains the end of the Sunday Vespers’ fourth antiphon (Sit nomen Domini), also the intonation and the differentia of the fifth antiphon (Nos qui vivimus) with the first half of the belonging psalm (Ps 113 In exitu Israel de Aegypto). The book cover may have gotten wet or it was treated with some kind of liquid, due to which the letters of the manuscript are somewhat blurred compared to the cover of B-III-191 (F 1102). Since the corpus of the host volume cannot be taken out of the boards and the turn-ins are not visible, the folio number of the fragment is unidentifiable. Based on the surviving parts of the corpus of the codex it may be one of fols. 150–154 (perhaps fol. 153).
