Two paper strips recovered from (and preserved together with) a 1482 incunabulum of Pseudo-Thomas Aquinas – De arte praedicandi, a volume that had originally belonged to the Benedictine cloister of Schuttern which was acquired by the Heidelberg University library in 1806 when the abbey was dissolved. These strips (formerly front paste-downs according to the volume's bibliographical information), which are among various repurposed manuscript fragments removed from the volume's binding during a conservation in 2000, contain Latin-texted polyphonic music notated on 5-line black staves in void black mensural notation (with a few full notes used both for semiminims and sesquialtera at the breve-level). They are adjacent strips cut from the same original leaf, together given the modern foliation 3ar and 3av by the library; the recto of the taller fragment (which I am calling strip A) on the Heidelberg University library's online images corresponds to the same side of the leaf as the verso of the shorter one (which I am calling strip B), and vice-versa. The extant part of the leaf's original recto is therefore composed of 3ar strip B adjoining 3av strip A, and its original verso of 3ar strip A adjoining 3av strip B. The fragmentary musical leaf preserves part of a troped Salve Regina setting, variously attributed to John Dunstaple or Leonel Power in other sources (many thanks to Robert Mitchell for identifying the music).
