That the Earth may be a Planet.
or, ſecondly, in the Axis, but out of the
Equator;
or, thirdly, beſides both of them.
But it is not placed according to any of theſe
ſcituations, therefore muſt it needs be in
the Centre.
1. ’Tis not in the Equator, and beſide the
Axis.
For then, firſt, there will be no E-
quinox at all in ſome places, when the Days
and Nights ſhall be of an equal length.
Se-

will not be of the ſame length;
becauſe,
then our Meridian-Line muſt divide the He-
miſphere into unequal parts.
2. ’Tis not in the Axis, but out of the
Equator;
For then, firſt, the Equinox would
not happen when the Sun was in the middle
Line between the two Solſtices, but in ſome

Secondly, There would not be ſuch a pro-
portion between the increaſe and decreaſe
of Days and Nights, as now there is.
3. ’Tis not beſides both of them: For
then, all theſe Inconveniences, and ſundry
others, muſt with the ſame neceſſity of con-
ſequence be inferred.
From whence it will
follow, That the Earth muſt be ſcituated
there, where the Axis and Equator meet,
which is in the Center of the World.
To this we grant, that the Earth muſt
needs be placed, both in the Axis and Equa-
tor;
and ſo conſequently, in the Centre of
that Sphere which we imagine about it:
