Collation Model for Ms. Codex 1233: [Notated breviary].

Breviary for use in the diocese of Cologne, probably in the Kölner Dom (cathedral). Made in the 15th century, it was used, annotated, and repaired through to the end of the 18th century. The breviary is preceded by a calendar in which the feasts of Saint Gereon and the Eleven Thousand Virgins, martyrs of Cologne, and of Saint Severin, an early bishop of Cologne, are written in red. The Sanctoral in the breviary itself includes offices for a number of saints associated with Cologne and for the Translation of the Three Kings, associated with relics kept on the high altar of the cathedral. The breviary includes foliation, headings, and annotations in 16th- through 18th-century hands, some of which were trimmed for the manuscript's current binding. It also includes burns (f. 23-24), marks from candle wax in night offices, and numerous parchment repairs to page edges. Chant tunes are written in Hufnagelschrift neumes on 4-line staves that are anachronistically ruled in color (brown, red, black, and yellow). Accompanying the manuscript is a device for marking several pages simultaneously, consisting of a small dowel with 6 cords knotted around it. The cords may have had decorative knotted ends originally, but all but one are now frayed.
