Abstract.

Johannes Hollandrinus, alongside a number of composers and theorists, belongs to a group of ‘shadowy figures’ who appear on the pages of the history of the music of the Middle Ages. He has been identified, successively, as Johannes Valendrinus, author of the treatise Opusculum monacordale; Johannes Hollandrinus, a scholar working in Prague; and the well-known theorist Johannes Boen. Research carried out over the period 2003–2016 as part of the team project Traditio Johannis Hollandrini revealed him to be the unintentional patron of a widespread didactic tradition, which probably began in the second half of the 14th century and continued to develop until the early decades of the 16th century in the area between the rivers Vistula and Rhine. The extant texts, of which there are more than 30, confirm the presence of this tradition both in city schools and in the university circles, including Prague, Krakow and Leipzig.
My intention is to show the various theoretical-musical and institutional aspects of this tradition that may be linked to the different hypotheses regarding Johannes Hollandrinus’s identity.
