thoſe near the Æquinoctial carried about in a greater circle, and
thoſe which are remote in a leſſer?
thoſe near the Æquinoctial carried about in a greater circle, and

SALV. To imitate the ſtarry Sphere, in which thoſe neareſt
to the Æquinoctial, move in greater circles, than the more
mote.

SIMP. Quarè Pila eadem ſub Æquinoctiali tota circa centrum
terr æ, ambitu maximo, celeritate incredibili; ſub Polo verò circa
centrum proprium, gyro nullo, tarditate ſupremâ volveretur?
[That is:] Why is the ſame ball under the Æquinoctial wholly
turned round the centre of the Earth in the greateſt
rence, with an incredible celerity; but under the Pole about its
own centre, in no circuite, but with the ultimate degree of
dity?

SALV. To imitate the ſtars of the Firmament, that would do
the like if they had the diurnal motion.

SIMP. Quare eadem res, pila v. g. plumbea, ſi ſemel terram
circuivit, deſcripto circulo maximo, eandem ubique non
migret ſecundùm circulum maximum, ſed tranſlata extra
ctialem in circulis minoribus agetur? [Which ſpeaketh thus:]
Why doth not the ſame thing, as for example, a ball of lead
turn round every where according to the ſame great circle, if once
deſcribing a great circle, it hath incompaſſed the Earth, but being
removed from the Æquinoctial, doth move in leſſer circles?

SALV. Becauſe ſo would, nay, according to the doctrine of
Ptolomey, ſo have ſome fixed ſtars done, which once were very
near the Æquinoctial, and deſcribed very vaſt circles, and now that
they are farther off, deſcribe leſſer.

SAGR. If I could now but keep in mind all theſe fine
tions, I ſhould think that I had made a great purchaſe; I muſt
needs intreat you, Simplicius, to lend me this Book, for there
not chuſe but be a ſea of rare and ingenious matters contained in
it.

SIMP. No Sir; hearken therefore. Si latio circularis

miſſile ignitum ſurſùm evolans ſcintilloſum caput ſurſùm à terrâ,
non autem circum volvatur, &c. [Which take in our idiom:] If
a circular lation is natural to heavy and light things, what is that
which is made according to a right line? For if it be natural, how
then is that motion which is about the centre natural, ſeeing it
