In this maner shall thou worche: consider thy rote first, the whiche is made the beginning of the tables fro the yere of oure lord 1397, and entere hit in-to thy slate for the laste meridie of December; and than consider the yere of oure lord, what is the date, and be-hold whether thy date be more or lasse than the yere 5 1397. And yf hit so be that hit be more, loke how many yeres hit passeth, and with so many entere into thy tables in the first lyne ther-as is writen _anni collecti et expansi_. And loke where the same planet is writen in the hede of thy table, and than loke what thou findest in directe of the same yere of oure lord whiche 10 is passid, be hit 8, or 9, or 10, or what nombre that evere it be, til the tyme that thou come to 20, or 40, or 60. And that thou findest in directe wryte in thy slate under thy rote, and adde hit to-geder, and that is thy mene mote, for the laste meridian of the December, for the same yere whiche that thou hast purposed. 15 And if hit so be that hit passe 20, consider wel that fro 1 to 20 ben _anni expansi_, and fro 20 to 3000 ben _anni collecti_; and if thy nombere passe 20, than take that thou findest in directe of 20, and if hit be more, as 6 or 18, than take that thou findest in directe there-of, that is to sayen, signes, degrees, minutes, and secoundes, 20 and adde to-gedere un-to thy rote; and thus to make rotes; and note, that if hit so be that the yere of oure lord be lasse than the rote, whiche is the yere of oure lord 1397, than shalt thou wryte in the same wyse furst thy rote in thy slate, and after entere in-to thy table in the same yere that be lasse, as I taught be-fore; and 25 than consider how many signes, degrees, minutes, and secoundes thyn entringe conteyneth. And so be that ther be 2 entrees, than adde hem togeder, and after with-drawe hem from the rote, the yere of oure lord 1397; and the residue that leveth is thy mene mote fro the laste meridie of December, the whiche 30 thou hast purposed; and if hit so be that thou wolt weten thy mene mote for any day, or for any fraccioun of day, in this maner thou shalt worche. Make thy rote fro the laste day of Decembere in the maner as I have taught, and afterward behold how many monethis, dayes, and houres ben passid from 35 the meridie of Decembere, and with that entere with the laste moneth that is ful passed, and take that thou findest in directe of him, and wryte hit in thy slate; and entere with as mony dayes as be more, and wryte that thou findest in directe of the same planete that thou worchest for; and in the same wyse in 40 the table of houres, for houres that ben passed, and adde alle these to thy rote; and the residue is the mene mote for the same day and the same houre. 45.
