Motions: For then, next to the Sun, or
Centre, there will be the Sphere of Mercu-
ry; which as it is but narrow in its Diame-
ter, ſo likewiſe is it quick in its Motion,
running its Courſe in eighty eight days:
Venus, that is next unto it, in 224 days:
The Earth in 365 days, or a Year: Mars
in 687 days: Jupiter in 4332 days: Saturn
in 10759 days. Thus likewiſe is it with
thoſe Medicean Stars that encompaſs Jupi-
ter. That which is loweſt amongſt them,
finiſhes his Courſe in two and twenty hours;
the next in three days and an half; the third
in ſeven days; and the fartheſt in ſeventeen
days. Now as it is (according to Ariſto-
tle’s conſeſſion) more likely that Nature
ſhould obſerve ſuch a due proportion betwixt
the Heavenly Orbs; ſo is it more probable,
that the Earth ſhould move, rather than the
Heavens.
