Magnetismus Planetarum

Consequence It follows from these, how, according to this previous rule, you can adjust the motions of the various planets to the earth, and compare them either to the earth moved or to the motionless earth, as also the Sun. It is true that whoever has scrutinized these little details, it is evident that, due to the length of the motion of the planets, much more easily, expediently, and truthfully, according to the hypothesis of a fixed earth, than of a moving one; vt or from this very Copernican hypothesis, the Ptolemaic & Tychonian hypothesis should merit to be preferred to many parasanges: which fusiùs perhaps I could demonstrate in this place, if I were not afraid to overstep the limits of my institution. Wherefore, having thus presupposed, let us now see by what means a system of this kind can be made by the Magnetic Art. PROBLEM 1. To present the hypothesis of the earth being moved by a magnetic device. when the motion of the earth was contrived, according to the mind of Gilbert, Above, in the first Problem of our Magnetic Mechanics, we have set forth, we do not wish to say any more about it here: only in this place, by what reason can the hypothesis of the moved earth and the sun be presented according to Kepler's Magnetic Artifice, we have taken it upon ourselves to demonstrate: that while we do so, no one has refuted us above He thinks that he wants to revive the opinion by this experiment, when rather from this his falsity and impossibility become more known, as will be evident from what has been said. Let the glass sphere be CD, according to Progymnasm. ours is filled with heterogeneous fluids, in the center of which is a long-necked glass flask, in which the vinegar is then distilled with the finest oil, arranged in the manner of a lamp; and he will bring back a lighted elychnium, the fiery globe of the Sun: for it is a wonder, what a pleasant spectacle the flame, gathered together as it were by the same refraction, under the waters in the center. When this is done, the STVX wheel will be adapted, with a cylinder moving in revolutions by the string X, to be subjected to exactly the same ratio of the sphere as we have prescribed above in Magnetic Mechanics: for the larger wheel ATVX will refer to the bearing of the Earth in the annual space around the motionless Sun, a portable cylinder equipped with its magnet. 24. cycled in the space of hours, the motion of the day: verily the epicycle in its monthly space

or they will obtain the setting of the Sun, which is regarded with the greatest pleasure of the soul. But if the cylinder R is circumscribed with its epicycle in its monthly space, the magnetic body of the moon will be circumscribed and S in its epicycle SDT around the earth in its monthly space, whence in B, ZYNOAOX, in S, νρς, or νορ, ννou, in T, αν, in D from the inhabitants of the earthly group will be seen. Eclipses will also be perfectly known, and the other phenomena usually explained in the Theory of the Moon, which, however, that they follow exactly, the earth, which is carried round by the motion of its magnet, must be outside the sphere of its activity, by which the moon is carried round. Er go we presented the hypothesis of the motion of the earth and the moon, which was to be done. Corollary 1. 10 to which it follows, that there is no motion of the Planets so intricate, which cannot be represented by this artifice, which we would gladly show here, unless the straits of time compel us to something else. wherefore it is sufficient for the ingenious Reader to propose here one example. Consequence II. 10 It also follows from these, contrary to Kepler, that this kind of motion of the heavenly bodies cannot be done by their own magnetic form by any reason, but that for the motions so varied and diverse of one body some intelligence is necessary, which, in constant motion, and according to the laws prescribed by the Author of nature for the good of the lower things and others on account of his ends he controlled them in so many ways. For even if the earth AB or any other planet moves by itself according to the succession of the signs by the motion of longitude, yet it cannot be said that it has at the same time also the motion of the intrinsic latitude. it cannot be caused by itself, except by various modifications, now a Wheel, now a Cylinder, imposed on him, now the lunar epicycle is supposed to be circulated before by the artist. Even so the heavenly bodies cannot undergo many and varied motions unless they are governed by an external, or what is the same, some intelligence appointed for that purpose. Further, if the so-called magnetic bodies were, with one magnetic body acting on another, great confusion would necessarily arise in the world. Thus, if the sun were magnetized at the center of the magnet, the free earth could by no means stand in the fluid place AB, without being attracted by the sun in the center, the stars would be united, or repulsed

Thus, if the sun were magnetized at the center of the magnet, the free earth could by no means stand in the fluid place AB, without being attracted by the sun in the center, the stars would be united, or repulsed and brought to a fixed position; nor does the rotation of the solar body around its axis do anything to meet these difficulties, since we have shown above that it is incapable of moving the planets. Again, if the Earth were magnetically drawn by the Sun in its own form into a circle, I mean, the Earth at the time of the solar eclipses by means of a lunar body, similarly constituted by the Magnetic, diverting and absorbing the Magnetic rays of the Sun from the Earth, not otherwise, and one Magnetic body resists the attack of another agent, viz. We have proved elsewhere by magnetic experiments, which, however, is by no means more clear than it ought to be said: it is likewise established that to bring round so many different planets, one magnet alone cannot be sufficient, but if they are to be brought round by the magnetic force of another magnet, each must be assigned its proper part, to which certain parts correspond, in a certain order of motion, which with the number and disposition of the bodies in the universe consist of no reason. It is added, finally, that the Planets, while they are in their ascendancy, being outside the sphere of activity, cannot be moved: all this is absurd. Therefore the planets are not magnetic bodies, nor do they magnetically attract each other, as was to be shown. Consequence 10. With this purpose he follows the Problem, how easy is the Keplerian Mechanism, or from our own calculation a little before the purpose (whereby the heavenly bodies, if they were Magnets, & of the tractive power in its diffusion from each Planet to each, the intervals we have calculated exactly) can be dissolved. For in that table, and in this Magnetic Problem, from the distances of the Planets, by which they are removed from each other, it is shown, the Planets according to Kepler's system, especially true Mars, Leo, and Saturn, since they are long established outside the Sphere of solar activity, and there is no magnet from the Sun reason to be circumscribed. For even if the radius of the sphere of solar activity is, according to our calculation, 214,500 Italian miles, since the distance from Mars, namely 5,120,529 miles, the radius of the sphere of solar activity is much greater, it will not be able to have any stimulating effect on Mars. You will not otherwise be able to reason about the other planets and their distances. And this is
