Just as the technology-minded theorists of the “Ars Nova” represented the first self-conscious avant garde faction in European literate music, so they inspired the first conservative backlash. It is found in the seventh and last book of the mammoth Speculum musicae (“The mirror of music”), at 521 chapters the largest of all medieval music treatises, completed around 1330 by Jacobus (or Jacques) de Liège. The author was a retired University of Paris professor (thus Jehan des Murs’s senior colleague) who had returned to his birthplace in Belgium to work on this grandiose project, which he intended as a summa summarum—a universal compendium—of musical knowledge. The young innovators of the “Ars Nova,” by extending the boundaries of musical theory, threatened the completeness of Jacobus’s account, so he tried to discredit their advance and thus neutralize the threat.
