The main hypotheses presented in this study - that Missa L'homme armé sexti was composed before the end of 1488 (i.e. before Josquin's presumed departure from Vienna) and was connected with the Hungarian court and the figure of Matthias Corvinus - builds on the findings of Bonnie Blackburn (dating of the Mass before 1489), Joshua Rifkin (Josquin's presence in Innsbruck in 1485 and the subsequent spread of his compositions in Central Europe) and David Fallows (Josquin's stay in Hungary during the second half of the 1480s). It seems clear that the predominant perception of Central Europe as a recipient of Franco-Flemish musical culture that was imported from Western Europe or Italy must be fundamentally revised.
Major centres of Central European culture actively participated in the creation of Franco-Flemish polyphony, it is necessary to integrate this area into the international discourse.
