Another maner conclusion, to knowe the mene mote and the
argumentis of any planete. To know the mene mote and the
argumentis of every planete fro yeer to yeer, from day to day,
from houre to houre, and from smale fraccionis infinite.
In this maner shalt thou worche; consider thy rote first, the
whiche is made the beginning of the tables fro the yer of oure
Lord 1397, and enter hit into thy slate for the laste meridie of
December; and than consider the yer of oure Lord, what is the
date, and behold whether thy date be more or lasse than the yer
1397. And yf hit so be that hit he more, loke how many yeres hit
passeth, and with so many enter into thy tables in the first lyne
theras is writen anni collecti et expansi-->. And loke where
the same planet is writen in the hed of thy table, and than loke
what thou findest in direct of the same yer of oure Lord which
is passid, he 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 direct wryt in thy slate under thy rote, and adde
hit togeder, and that is thy mene mote, for the laste meridian
of the December, for the same yer which that thou hast purposed.
And if hit so he 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 nomber passe 20,
than tak that thou findest in direct of 20, and if hit he more, as 6 or 18, than tak
that thou findest in direct thereof, that is to sayen, signes,
degrees, minutes, and secoundes, and adde togedere unto thy rote;
and thus to make rotes. And note, that if hit so be that the yer
of oure Lord be lasse than the rote, which is the yer of oure
Lord 1397, than shalt thou wryte in the same wyse first thy rote
in thy slate, and after enter into thy table in the same yer that
be lasse, as I taught before; and 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
withdraw hem from the rote, the yer of oure Lord 1397; and the
residue that leveth is thy mene mote for the laste meridie of
December, the whiche thou hast purposid; and if hit so he that
thou wolt witen 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 December in the maner as I have taught, and
afterward behold how many monethes, dayes, and houres ben passid
from the meridie of December, and with that enter with the laste
moneth that is ful passed, and take that thou findest in direct
of him, and wryt hit in thy slate; and enter with as mony dayes
as be more, and wryt that thou findest in direct of the same
planete that thou worchest for; and in the same wyse in 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.
