To knowe the latitude of planetes fro the wey of the sonne, whethir so they be north or south fro the forseide wey.


678

Loke whan that a planete is in the lyne meridional, yf that hir altitude be of the same height that is the degre of the sonne for that day, and than is the planete in the verrey wey of the sonne and hath no latitude. And if the altitude of the planete be heigher than the degre of the sonne, than is the planete north fro the wey of the sonne such a quantite of latitude as shewith by thin almykanteras. And if the altitude of the planete be lasse than the degre of the sonne, than is the planete south fro the wey of the sonne such a quantite of latitude as shewith by thin almykanteras. This is to seyn, fro the wey where as the sonne went thilke day, but not fro the wey of the sonne in every place of the zodiak.
