1of the cauſe, but findeth no fault with the method of it; that
is, denieth that there is any mutation to be ſeen in the altitude of
the Pole, but doth not blame the inquiſition, for not being
ted to the finding of what is ſought, he thereby ſheweth, that he
alſo eſtecemed the Polar altitude varied, or not varied every ſix
moneths, to be a good teſtimony to diſprove or inferre the annual
motion of the Earth.
A ſtronomeys,
perhaps, have not
known what
pearances ought to
follow upon the
nual motion of the
Earth.
Copernicus
derſtood not ſome
things for want of
Inſtruments.
Tycho and
thers argue
gainſt the annual
motion, from the
invariable
tion of the Pole.

Rothmannus.
SIMP. In truth, Salviatus, my opinion alſo tells me, that the
ſame muſt neceſſarily enſue: for I do not think that you will
ny me, but that if we walk only 60. miles towards the North,
the Pole will riſe unto us a degree higher, and that if we move
60. miles farther Northwards, the Pole will be elevated to us a
degree more, &c.
Now if the approaching or receding 60. miles
onely, make ſo notable a change in the Polar altitudes, what
alteration would follow, if the Earth and we with it, ſhould
be tranſported, I will not ſay 60. miles, but 60. thouſand miles
that way.
SALV. It would follow (if it ſhould proceed in the ſame
proportion) that the Pole ſhall be elevated a thouſand degrees.
See, Simplicius, what a long rooted opinion can do. Yea, by
reaſon you have fixed it in your mind for ſo many years, that it
is Heaven, that revolveth in twenty four hours, and not the
Earth, and that conſequently the Poles of that Revolution are in
Heaven, and not in the Terreſtrial Globe, cannot now, in an
hours time ſhake off this habituated conceipt, and take up the
contrary, fancying to your ſelf, that the Earth is that which
veth, only for ſo long time as may ſuffice to conceive of what
would follow, thereupon ſhould that lye be a truth.
If the Earth
Simplicius, be that which moveth in its ſelf in twenty four hours,
in it are the Poles, in it is the Axis, in it is the Equinoctial, that
is, the grand Circle, deſcribed by the point, equidiſtant from the
Poles, in it are the inſinite Parallels bigger and leſſer deſcribed by
the points of the ſuperficies more and leſſe diſtant from the Poles,
in it are all theſe things, and not in the ſtarry Sphere, which, as
being immoveable, wants them all, and can only by the
tion be conceived to be therein, prolonging the Axis of the Earth
ſo far, till that determining, it ſhall mark out two points placed
right over our Poles, and the plane of the Equinoctial being
tended, it ſhall deſcribe in Heaven a circle like it ſelf.
Now if the
true Axis, the true Poles, the true Equinoctial, do not change
in the Earth ſo long as you continue in the ſame place of the
Earth, and though the Earth be tranſported, as you do pleaſe,
yet you ſhall not change your habitude either to the Poles, or to
the circles, or to any other Earthly thing; and this becauſe, that
that tranſpoſition being common to you and to all Terreſtrial
