The two folios are consecutive: they contain the Masses for Holy Wednesday and Maundy Thursday and the initial antiphons for the Mandatum rite; it belonged to a section of chants for Holy Week.
Very interesting are the three Antiphons on f. B verso, for Maundy Thursday. These Antiphons are not referred to in the Missal of Braga.
Condition of document:
Bifolium slightly damaged. It was bound with a register book, which it still covers. There are wrinkles, folds, spots of humidity, small holes, pasted paper and effacements that make the reading difficult and cause loss of contents.
Folio A is in better condition; in the upper part of B verso the ink is mostly vanished.
