P-Cua (Coimbra) Arquivo Distrital e da Universidade IV-3ª Gav. 44 (17)
Some chants for Easter sunday on the recto; then several chants that variously belong to the week following Easter. These are however too loosely arranged and their relative rubrics almost always unreadable to connect them to any more precise day inside of this week. They have been categorized under the general feast 'In tempore Paschae' (Cantus feast ID 08000000)
The rather rare antiphon 'Alleluia Cognoverunt dominum' seems to be typical of the Iberian Peninsula, with 10 sources out of the current 11 in the Cantus Database, as of 2021, being Iberian.
Recto, bottom margin, in pencil: "Capa de um livro do notº Antº Martins, Coimbra (157-)"; "INV./ BOL./ 96 (43); IV-3ª S - GV. 44 (17)".
Together with P-Cua IV-3ª Gv 044 (16) and (18), 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.
