not so much in Geographie as in Astronomie.

_The Zodiake is a circle which compasseth the earth like a belt,
crossing the æquator slopewise, not streight as the Meridians
doe._ Opposite to it in the Heauens is another circle of the same
name, wherein are the 12. signes, and in which the Sunne keepes
his owne proper course all the yeare long, neuer declining from
it on the one side or other. The vse hereof in Geography is but
litle only to shew what people they are ouer whose heads the
Sunne comes to bee once or twice a yeare; who are all those that
dwell with in 23. degrees of the Aequator; for so much is the
declination, or sloping of the _Zodiacke_. This circle is also
called the Eclipticke line, because when the Sunne and Moone
stand both in this circle opposite each to other, then there
happens an Eclipse of the Sunne or Mone, vpon a globe it is
easily discerned, by the sloping of it from the Aequator, and the
diuisions of it into 12. parts, and euery of those 12. into 30.
degrees.

_These are the greater circles: the lesser follow; which are all
of one nature, and are called by one generall name: sc.
Parallels, because they are so drawen on each side of the
Aequator, as they are equidistant vnto it euery way._ Many of
this kinde are drawne vpon the globe (as is easie to bee seene)
and may bee conceaued to bee drawne vpon the earth: but there are
only two sorts cheifely to bee marked: namely the

{ Tropickes and the }
{ Polar circles. }
