The 'Glogauer Liederbuch', once held in the 'Preussische Staatsbibliothek' in Berlin and now to be found in the collection of 'Biblioteka Jagiellonska' in Kraków, counts among the most valuable sources of polyphonic music of the second half of the 15th century. The manuscript was created in Silesia, most probably in the Augustinian monastery in Zagan, it was copied around 1480, and is one of the earliest examples of musical notation in partbooks. The article provides a description of the repertory contained in the Liederbuch. The analysis of its concordances leads the author to the conclusion that manuscripts originating from Naples, particularly the Seville Chansonnier and the Mellon Chansonnier, hold an important place among them. The Neapolitan context is explained by referring to the cultural and political history of Silesia, linked to the court of Hungarian king Matthias Corvinus at the time. The reciprocal interrelations and the migration of the repertoire between Silesia and Naples permit the author to question the stability of the traditional differentiation between the centre and the periphery.
