nitude of the body is that which maketh it of exceeding ſlow, to
become exceeding ſwift, although it continueth ſtill the ſame, and
thus the velocity encreaſeth, not beyond the model of the
ject, but rather according to it, and to its magnitude; very
ferently from the imagination of Kepler.

SALV. I do not believe that this Author hath entertained ſo
mean and poor a conceit of Kepler, as to perſwade himſelf that
he did not underſtand, that the higheſt term of a line drawn from
the centre unro the Starry Sphere, moveth more ſwiftly than a
point of the ſame line taken within a yard or two of the centre. And
therefore of neceſſity he muſt have conceived and
ed that the mind and intention of Kepler was to have ſaid, that
it is leſſe inconvenient to encreaſe an immoveable body to an
traordinary magnitude, than to aſcribe an extraordinary velocity
to a body, though very bigge, having regard to the model,
that is to the gauge, and to the example of other natural bodies;
in which we ſee, that the diſtance from the centre encreaſing, the
velocity diminiſheth; that is, that the periods of their
ons take up longer times. But in reſt which is not capable of
mentation or diminution, the grandure or ſmalneſſe of the body
maketh no differeuce. So that if the anſwer of the Author would
be directed againſt the argument of Kepler, it is neceſſary, that
that Author doth hold, that to the movent principle its one and the
ſame to move in the ſame time a body very ſmall, or very
menſe, in regard that the augmentation of velocity inſeparably
attends the augmentation of the maſſe. But this again is contrary
to the Architectonical rule of nature, which doth in the leſſer
Spheres, as we ſee in the Planets, and moſt ſenſibly in the
cean Stars, obſerve to make the leſſer Orbs to circulate in ſhorter
times: Whence the time of Saturns revolution is longer than all
the times of the other leſſer Spheres, it being thirty years; now
the paſſing from this to a Sphere very much bigger, and to make
it move in 24. hours, may very well be ſaid to exceed the rules of
the model. So that if we would but attentively conſider it, the
Authors anſwer oppoſeth not the intent and ſenſe of the argument,
but the expreſſing and manner of delivering of it; where again
the Author is injurious, and cannot deny but that he artificially
diſſembled his underſtanding of the words, that he might charge
Kepler with groſſe ignorance; but the impoſture was ſo very dull
and obvions, that he could not with all his craft alter the
on which Kepler hath begot of his Doctrine in the minds of all
the Learned. As in the next place, to the inſtance againſt the
perpetual motion of the Earth, taken from the impoſſibility of
its moving long without wearineſſe, in regard that living
mean and poor a conceit of Kepler, as to perſwade himſelf that
he did not underſtand, that the higheſt term of a line drawn from
the centre unro the Starry Sphere, moveth more ſwiftly than a
