Compiled and handwritten probably in or shortly after 1583 at Rouen, not unlikely by one of the Celestine monks named in the inscription on the t.p. of the printed calendar with which the manuscript is bound (Pierre Du Souchis (-ay?) or Louis Cous...[rest of name lost through cropping])
Leaves [1-51] are numbered 42-99, in continuation of the 41 leaves of the printed calendar; the last 5 leaves are blank.
Signatures: F-M⁸, intended as continuation of the signatures of the printed calendar (in the copy involved the last printed signature is E) although the paper is different and gathered as in 4to, with horizontal chainlines and the watermark (vase with one handle) always in the gutter.
Written in black and red, the black text mostly in a utilitarian cursive, 25-32 long lines; the very faded red captions use a hybrid script; red is used also for versals, for edge-to-edge framing of each page, and variously in the tables.
The Computus is divided in 7 treatises.
Caption, leaf 73a: Sequuntur Ephemerides compendiosae ad sciendum in quo signo Zodiaci planetae sint ...; the tables cover years 1583 through 1605, ending on leaf 80a.
Includes numerous tables, zodiacal signs, a diagram ("Venti duodecim," leaf 72b)
