349169That the Earth may be a Planet.
Where ſuppoſe the Sun to be at A, the
Circle (BGM) to be the Orb of the Earth's
Motion;
and that above it, noted with the
ſame Letters, to be the Sphere of Jupiter;
and the uppermoſt of all, to be a part of
the Zodiack in the Starry Heaven.
Now if you conceive the Letters, BCD
EFGHI KLM, and abcdefghiklm,
to divide the Earth’s Orb, and that of Ju-
piter, into ſeveral parts, proportionable to
the ſlowneſs or ſwiftneſs of their different
motions, (Jupiter finiſhing his Courſe in
twelve Years, and the Earth in One) then
ſuppoſing the Earth to be at the Point (B),
and Jupiter likewiſe in his Orb to be ſcitua-
ted at (b), he will appear unto us to be in
the Zodiack at the point (r).
But after-
wards, both of them moving forward to the
Letter (Cc), Jupiter will ſeem to be in the
Zodiack at (v), as having paſſed directly
forward according to the order of the Signs.
And ſo likewiſe each of them being tranſ-
ferred to the places (Dd) (Ee), Jupiter
will ſtill appear Direct, and to have moved
in the Zodiack unto the Points (yz).
But
now vvhen the Earth comes to be more im-
mediatly interpoſed betwixt this Planet and
the Sun;
as vvhen both of them are at the
Letter (Ff), then vvill Jupiter bediſcerned
in the Zodiack at (x).
So that all the
vvhile the Earth vvas paſſing the Arch (E
F), Jupiter did ſtill remain betwixt the
Points (z) and (x), and therefore muſt
ſeem unto us as if he vvere Stationary;
