Single leaf from an antiphoner with table of contents and an added chant for Dom 2. post Pascha. 50.0 x 37.7 cm; writing area 38.0x 26.5 cm.
Narrow vertical margins visible. Labeled 144 in upper right. Table of Contents suggests the volume only contained chants for the Temporale.
A late Gothic hand is visible at the top of the fragment, and on the verso; stenciled "print-like" letters are also present. The page has been repurposed and re-decorated at least once.
Four-line red staff (six per page). Two musical hands present. One has a slightly tilted c-clef and virga with thin descenders; the other uses curved c and f clefs, a rounded flat, and puncta that have hairlines on either side, as well as a small and angular custos.
A figure of a nun in blue with a white wimple and holding a book sits inside a red E, which in turn is inside a gold square. A border of pink, blue, and purple bell-shaped flowers and their leaves curves into three sides of the page, with gold bezants.
Although likely purchased in Paris in the 1930s, certain factors (such as the spelling "alleluja" suggest a German or Dutch origin.
The melody for "Ego sum pastor bonus," in mode 8, is somewhat unusual, and may be a clue to the page's origins.
The table of contents (which seems to be in an earlier hand than the preceding antiphon) gives Easter II on folio 99; this antiphon is likely an addition to the very end of the antiphoner.
