One parchment fragment, the subject of Höfler1966, dating from the 2nd half of the 14th century, comprises of two pages of size 30 x 10.5 cm and 30 x 22 cm, which form a double folio. A middle strip 1.5 cm wide is missing, and the first sheet is missing a 8 cm wide edge. Both parts were glued in a manuscript from Upper Carniola (call number 75, a Glosa supra libros de anima) - the larger part on the inside of the front cover, the smaller on the inside of the back cover.
The largest part of the examined fragment is devoted to various problems of mensural notation, examining the problem of groups with different combinations of semibreves minor and semibreves major, typical of the early/mid-14th century Italian ars nova. The problems in the form found in our manuscript are also found with Marchettus of Padua (“Pomerium musicae mensuratae”): the two questions are about the interpretation via naturae of groups that are exclusively made up of semibreves minor and the interpretations via artis of groups with semibreves and semibrevis caudate major.
We can conclude that our fragment was made by writing out note examples from a mensural debate near Marchettus of Padua and thus represents an interesting document of ars nova on Slovene territory.
