To knowe the declinacioun of eny degre in the zodiak fro the equinoxiall cercle.
Set the degre of eny signe upon the lyne meridionall, and
rekne hys altitude in the
almykanteras fro the est
orisonte up to the same degre set in the forseide lyne, and set
there a prikke; turne up than thy riet, and set the heved of
Aries or Libra in the same meridionall lyne, and set there a
nother prikke. And whan that this is don, considre the altitudes
of hem bothe; for sothly the difference of thilke altitudes is
the declinacioun of thilke degre fro the equinoxiall. And yf it
so be that thilke degre be northward fro the equinoxiall, than
is his declinacyoun north; yif it be southward, than is it
south.
