Abstrakt
The paper deals with a group of four Luython's masses entitled Quodlibetica published in his Liber primus missarum (1609). Firstly, it summarizes the main compositional techniques used within the sixteenth-century polyphonic mass ordinaries, then it examines a handful of authors - mainly from the Habsburg court circle - who have chosen such a title for their compositions.
The main focus of the paper is then concentrated to missae quodlibeticae by Jacobus Vaet and Carl Luython.
