A single leaf fragment on parchment, c. 506 x 386 mm, with a six line blue initial, decorated with a geometric pattern in red and purple.
 
Ruled in lead point, c. 475 x 276 mm (visible), with music in square notation on five-line staves ruled in red with lyrics in black ink in prescissa script and rubrics in red.
 
The six letter decorated initial on the recto opens the text for the cantus, ‘Beatus vincentius applicatus tormentis alacri’, (’Blessed Vincent, applied to the torments of the zealous’), which continues to the verso. A good example of a large antiphonal leaf. The upper and side margins of the leaf has been trimmed, there is a tear and loss to the lower margin in the corner. There is evidence of liquid marks to the parchment.
