Understond wel that thy zodiak is departed in two halve
circles, as fro the heved of Capricorne unto the heved of Cancer,
and ageyn-ward fro the heved of Cancer unto the heved of

the sonne goth in wynter, and the heved of Cancer is the heighist
point in which the sonne goth in somer. And therfore understond
wel that eny two degrees
that ben ylike fer fro eny
of these two hevedes, truste wel that thilke two degrees ben of
ilike declinacioun, be it southward or northward, and the daies
of hem ben ilike of lengthe and the nyghtes also, and the
shadewes ilyke, and the altitudes ylike atte midday for evere.
