Questions of authorship are central to the late thirteenth-century motet
repertoire represented by the seventh section or fascicle of the
Montpellier Codex (Montpellier, Bibliothèque interuniversitaire, Section
de médecine, H. 196, hereafter Mo). Mo does not explicitly
attribute any of its compositions, but theoretical sources name Petrus
de Cruce as the composer of the two motets that open fascicle 7, and
three later motets in this fascicle are elsewhere ascribed to Adam de la
Halle. This monograph reveals a musical and textual quotation of Adam's
Aucun se sont loe incipit at the outset of Petrus's Aucun ont trouve
triplum, and it explores various invocations of Adam and Petrus - their
works and techniques - within further anonymous compositions. Authorship
is additionally considered from the perspective of two new types of
motets especially prevalent in fascicle 7: motets that name musicians,
as well as those based on vernacular song or instrumental melodies, some
of which are identified by the names of their creators. This book offers
new insights into the musical, poetic, and curatorial reception of
thirteenth-century composers' works in their own time. It uncovers,
beneath the surface of an anonymous motet book, unsuspected interactions
between authors and traces of compositional identities.
