The subject of this master thesis is the paleographical analysis of the script and notation of the Exultet chant contained in two 11th-century manuscripts: Vekenega's Book of Gospels from the monastery of St. Mary in Zadar and the ritual from the Monte Cassino monastery. In addition to script and notation, as the main parts of this research, it was inevitable to include all those accompanying elements characteristic of the area with an, for this work, arbitrary name - the Beneventan cultural region. The first step in this direction was the textual analysis of the chant. It included a comparison of the Beneventan and the Franko-Roman versions of the chant, with the latter slowly replacing the use of the Beneventan in the context of the church reform of the 11th century. Paleographic analysis of the script and notation are the basic and most important parts of the work. The comparison of the round Dalmatian and the angular Montecassino Beneventan script, as well as the comparison of the neums from the two studied manuscripts, is supported by a large number of pictorial contributions, and these had the task of showing how numerous developmental changes, especially in the second reform half of the 11th century, affected various written and musical forms of Zadar and Monte Cassino. Recent research has also shown how important it is to take into account the manuscript and its function as a whole, if we do not adequately approach the two previously mentioned analyses. Furthermore, viewed from the aspect of illuminations, the Zadar area is particularly interesting, since already on the very example of the song from Vekenega's Book of Gospels, we come across influences from different areas, which due to their fragmentary nature are more justified to be called cultural transfers. The graphic analysis of the chants and the Beneventan liturgy are two topics that had the task of rounding up everything previously presented and thereby introducing the research into concluding considerations. Although much has been written and although many historical facts and processes known today are seen from different angles, the aim of this work was to show the relationship between the center and the periphery in the context of the so-called of the Beneventan cultural circle, on the example of the two monasteries from Zadar and Monte Cassino. All the reform changes of the second half of the 11th century, due to the strong ecclesiastical and political connection with Rome, first appeared in Monte Cassino, and from there gradually dispersed throughout the mentioned area and at one point reached Zadar. Interdisciplinary research of the chants from the two manuscripts we studied, that is, looking at numerous elements from different angles, enables the evaluation of historical knowledge already established and the finding of new adequate conclusions.
