The text has become out of order, and should be: ff. 13v-r, 12v-r, 9r-10v, 11r-v.
There is no indication of provenance on the fragment; the catalogue information at Fragmentarium gives a Rheinland attribution, but the collection of saints (e.g. St-Malo) has a French aspect.
The notation is messine on a three-line drypoint staff, with a red F line, faint traces of a yellow c-line, and an A-clef.
