Full-page decoration on fol. 85v.
The upper three quarters of the page are taken by a miniature and a historiated initial. Both units are enclosed by the same frame, with a horizontal division between both sections.
The upper section shows the Last Supper on a podest, with Jesus and 11 apostles sitting on a bench. Judas is sitting on a stool on the other side of the table, putting his hand into a vessel full of water, just as Jesus does. Jesus is sitting on the left shorter side of the table, John reclining on his breast and Jesus resting his arm on John's back. Five apostles are shown with knives, two of them are holding a piece of bread, and one of them is drinking wine. Except for Judas, the heads of all the protagonists are nimbed.
The lower section holds the initial C from the text “Corriverencaet” further down on the page. Letter C is set against a gilded background, with three men on the left and three on the right. All of them wear a short veil, and the man in the foreground grabs a red hat in his hand. In the initial, the consecration takes place. A monk holds up the host in front of an altar with two candles and the open mass book. The book has inscriptions in Hebrew. On the left side of the mensa is a woman and on the right side a man in prayer. On the right, an other monk is holding a (Paschal?) candle.
In the lower quarter of the page is the text block, which consists of one line of music notation and one lin of the text, framed and gilded in capital letters set against a blue background.
The border extends on three margins, and holds twelve medaillions with saints: Saint Jerome, Pope Gregory, Pope Sylvester, the martyrs Saint Stephan, Saint Lawrence, Saint Pancras and an unidentified martyr, Saint Agnes, Mary Magdalene, Saint Nicholas and John the Baptist. Stylised flowers, leaves and intersecting knotworks connect the medaillons, each of them framed by stylised flowers and leaves.
