HERE BIGINNEN THE CONCLUSIONS OF THE ASTROLABIE.


  1. TO FYNDE THE DEGREE IN WHICH THE SONNE IS DAY BY DAY, AFTER HIR COURS
      A-BOUTE.

  [HIC INCIPIUNT CONCLUSIONES ASTROLABII; ET PRIMA EST AD INVENIENDUM
      GRADUS SOLIS IN QUIBUS SINGULIS DIEBUS SECUNDUM CURSUM SOL EST
      EXISTENS.]

  Rekene and knowe which is the day of thy monthe; and ley
  thy rewle up that same day; and thanne wol the verray point of
  thy rewle sitten in the bordure, up-on the degree of thy sonne.
  Ensample as thus; the yeer of oure lord 1391, the 12 day of
  March at midday, I wolde knowe the degree of the sonne. I               5
  soughte in the bak-half of myn Astrolabie, and fond the cercle of
  the dayes, the which I knowe by the names of the monthes writen
  under the same cercle. Tho leide I my rewle over this forseide
  day, and fond the point of my rewle in the bordure up-on the
  firste degree of Aries, a litel with-in the degree; and thus knowe     10
  I this conclusioun. Another day, I wolde knowe the degree of
  my sonne, and this was at midday in the 13 day of Decembre; I
  fond the day of the monthe in maner as I seide; tho leide I my
  rewle up-on this forseide 13 day, and fond the point of my rewle
  in the bordure up-on the first degree of Capricorne, a lite with-in    15
  the degree; and than hadde I of this conclusioun the ful
  experience. And for the more declaracioun, lo here thy figure.

  2. TO KNOWE THE ALTITUDE OF THE SONNE, OR OF OTHRE CELESTIAL BODIES.

  [DE ALTITUDINE SOLIS ET ALIORUM CORPORUM SUPRA CELESTIUM.]

  Put the ring of thyn Astrolabie up-on thy right thoumbe, and
  turne thy lift syde agayn the light of the sonne. And remeve
  thy rewle up and doun, til that the stremes of the sonne shyne
  thorgh bothe holes of thy rewle. Loke thanne how many degrees
  thy rewle is areised fro the litel crois up-on thyn est line, and tak   5
  ther the altitude of thy sonne. And in this same wyse maistow
  knowe by nighte the altitude of the mone, or of brighte sterres.
  This chapitre is so general ever in oon, that ther nedith no more
  declaracion; but forget it nat. And for the more declaracioun,
  lo here the figure.                                                    10

  3. TO KNOWE EVERY TYME OF THE DAY BY LIGHT OF THE SONNE, AND EVERY TYME
      OF THE NIGHT BY THE STERRES FIXE, AND EKE TO KNOWE BY NIGHT OR BY DAY
      THE DEGREE OF ANY SIGNE THAT ASSENDETH ON THE EST ORISONTE, WHICH
      THAT IS CLEPED COMMUNLY THE ASSENDENT, OR ELLES ORUSCUPUM.
