An ecclesiastical and astronomical calendar, together with the tables and figures of the zodiac: folding calendar on a sheet of parchment. Originally two rows, each of twenty four folds, but the first folds in the lower row ( lower if the sheet is looked at from the side containing art. 1) are missing and the first fold in the upper row has been sewn to the foot of the second fold. Three membranes were joined to make a sheet.

In both rows on one side, the calendar is in blue, red, green and black, four folds to a month. The second half of January is missing. Entries in red include Edwardii Regis and Translacio Edwardi Regis (20 March, 13 October); in black, Translacio Mildride (13 July). Each feast is illustrated by a conventional head, sideways, in coloured penwork: kings crowned, abbots tonsured etc. The ruling is in red and green inks.

On the other side, the other way up: (a) in the upper row, the sign of the zodiac in each month, followed by its occupation; (b) in the lower row, an astronomical calendar, 1 january to 15 June on 22 folds, four to a month.

(a) The January sign and occupation are missing. The December occupation came on the fold which was exposed when the sheet was closed and has been rubbed away.

(b) The first two folds were left blank.
