Together with P-Cua IV-3ª Gv 044 (16) and (17), this fragment is one of three leaves dismantled from the same lost antiphonary: evidences for their common source are the identity, among others, of: (1) textual and musical ductus (especially of more complex shapes such as 'a', rising liquescences, quilisma ...); (2) decorations (filling coloured lines inside of bigger capitals, dots at the extremities of serifs); (3) occasional red-line boxings for rubrics, and so forth... Fragments 17 and 18 were used as a cover in the same notebook belonging to the notary António Martins in the late 16th century.
