To knowe with which degre of the zodiak that eny planete
ascendith on the orisonte, wheither so that his latitude be north or south.
Know by thin almenak the degre of the ecliptik of eny signe
in which that the planete is rekned for to be, and that is clepid
the degre of his longitude. And know also the degre of his
latitude fro the ecliptik north or south. And by these ensamples
folewynge in speciall maist thou worche in general in every
signe of the zodiak:
The degree of the longitude peraventure of Venus or of
another planete was 1 of Capricorne, and the latitude of him was
northward 4 degrees fro the ecliptik lyne. Than tok I a subtil
compas, and clepid that oo point of my compas A, and that other
point F. Than tok I the point of A and sette it in the ecliptik
lyne in my zodiak in the degre of the longitude of Venus, that
is to seyn, in the 1 degre of Capricorne; and than sette I the
point of F upward in the same signe by cause that latitude was
north upon the latitude of Venus, that is to seyn, in the 4 degre
fro the heved of Capricorne; and thus have I 4 degrees bitwixe
my two prickes. Than leide I down softly my compas, and sette the
degre of the longitude upon the orisonte; tho tok I and waxed my
label in manere of a peire tables to receyve distinctly the
prickes of my compas. Tho tok I thys forseide label, and leyde
it fix over the degre of my longitude; tho tok I up my compas and
sette the point of A in the wax on my label, as evene as I koude
gesse, over the ecliptik lyne in the ende of the longitude, and
sette the point of F endelong in my label upon the space of the
latitude, inward and over the zodiak, that is to seyn northward
fro the ecliptik. Than leide I doun my compas, and loked wel in
the wey upon the prickes of A and of F; tho turned I my ryet til
that the pricke of F satt upon the orisonte; than saw I wel that
the body of Venus in hir latitude of 4 degrees septemtrionals
ascendid, in the ende of the 8 degre, fro the heved of
Capricorne.
And nota--> that in this manere
maist thou worche with any latitude septemtrional in alle signes. But sothly
the latitude meridional of a planete in Capricorne ne may not be
take by cause of the litel space bitwixe the ecliptyk and the
bordure of the Astrelabie; but sothely in all othre signes it
may.
