Bifolium on parchment, c. 159 x 227 mm (c. 105 x 74 mm) with one four-line initial in blue, and three three-line initials alternating in blue and red, the red having purple pen ornaments extending into the margins.
 
Ruled in ink for two columns of 32, written in a gothic script in brown ink, rubrics and pagination in red, and 67 single line initials alternating in red or blue with some purple line decoration to the red letters, and yellow highlights. Binding tie to inner margin.
 
The first three-line initial to the first recto opens Psalm 104, ‘Confitemini d[omi]no et i[n]vocate nome[n] eiu[s] adnu[n]tiate int[e]r gentes op[era] ei[us]’, (’Give thanks to the Lord and call on his name. Declare his deeds among the nations’). 
 
A very good example of a bifolium. Some discolouration to the parchment, small holes and nipples to edges and inner margin, some rubbing to script, some corrosion to ink most likely due to iron gall which impacts legibility slightly.
