Re. deat igitur in centri loçum tellus, redeat in circulum suum Sol, caeterique planetae, sic enim diuinae, sic humanae volunt rationes. Lectores autem Gilberto & Keplero Magneticae huius vertiginis authoribus hanc falsitatem ignoscant velim, qui, dum Stare negant terram; cum tot miracula narrant, In rate scribentes forsan vterque fuit. QVAESTIO II. Vtrum memorate mundanorum motuum hypotheses Magnetica arte effici possint.

You punish her without any foundation and reason, any license to commingle the sun and the other planets, while the sun and other planets are magnetized in one way, one way denies, one way attractive, one way directive, or one repulsive force to pollinate the fibers no longer at the poles; but he asserts that all things are made into a circle, now all motions by magnetic force alone, now by illuminative force, a little after a certain kind of mind surrounds him, for neither Euripus can will so many tides, nor can Chamaeleon transform himself into so many colors, as many tides, and as many forms he in establishing He assumes the worldly system, which tide, whoever wishes to know more clearly, should go to its celestial physics; for from it it will be plainly evident how much he tortures himself, how ridiculously he is threatened, how violently he drives the earth and the other planets into orbits by the magnetism of the sun at will, which he does not imagine. or from this very thing it may be permitted to conclude, how false, frivolous, futile, and feeble that philosophy is to be considered, which besets its custodian with so many scruples and perplexities; , turning to the vertigo of the rest of the planets, he had worn out his wits, succumbing as if overcome by vertigo, frankly confessing his vain and useless labor with these words. Thus far, indeed, the probability of most of the causes brought forward was evident; their faith is the greatest that anyone can share.] You have said nothing more truly, Kepler. Re. therefore let the earth be in the center, let the sun return to its circle, and the rest of the planets, for so the divine and so the human reasons will. But I would like the readers of Gilbert & Kepler's Magnetics, the authors of this vertigo, to forgive this falsity, who, while Stare denies the earth; when they narrate so many miracles, in the rate of writing it was perhaps both. QUESTION II Remember whether the hypotheses of worldly motions can be made by magnetic art. In the foregoing we have shown that the natural motion of the Magnetic Earth, the Sun, and the Moon is false and fictitious; now it remains to investigate; but not at least by a certain artificial constitution, the hypotheses of the said motions are demonstrated by the aid of the magnetic art.

demonstrari possint, quod quidem vt solide praestetur, suppono prius, eam esse duorum corporum mobilium affectionem, vt alterutro, vel stante, vel in orbem circumacto, eadem semper facies corporum, eadem apparentia iuxta Opticorum regulas resultet; siue enim circa me immotum aliquod corpus, siue ego circa corpus immotum circumagar, semper eundem corporum situm, positionemque, eademque consequenter apparentia resultare necesse est, ita quoque perinde est, siue assatura circa ignem, siue hic circa assaturam circum feratur, cum idem semper assationis effectus proueniat: ita denique eadem hora monstrabitur, siue lux circa horologium immotum, siue horologium circa lucem immotam circumferatur, quae omnia fuse supra in Geometria, & Astronomia nostra scioterica ostendimus; vi proindè ex hoc capite Copernicaea sententia difficulter argui possit; Nihilominus non obstante dictorum corporum affectione, dico, quod irrationabiliter ageret, qui, cum facilius obelisci alicuius inscriptiones, circumire possit, circa se obeliscum gyrari mandaret; ita insanùs denique omnium opinione habendus esset, qui cum horam ex horologio immoto facile dignoscere possit, horologium circa Solem immotum deferre attentaret: etsi hoc facto idem effectus seque retur; ita quoque Copernicani illi Cyclopes temerarij habendi sunt, qui terrae crassissimi & ponderosissimi corporis quiete naturali neglecta, eam inutili profectò, & irrito labore, per immensa caelorum spacia in incertum versant; corpus verò Solis igneum & ex se & sua natura motum affectans, centro vniuersi affigunt. Non debebant ipsi, quid Optica praescriberet, sed quid corporum conseruationi salutarius foret, si prudenter philosophari volebant, attendere. Habet enim multa huiusmodi Mathematica, queis ex falsis & impossibili bus vera & certissima concludit: Ita diuina illa Algebra ex nihilo aliquid producit, dum ex numeris minoribus nihilo, ex se falsis, & impossibilibus in abstrusissimarum quaestionum quarumuis solutionem deuenit. Ita è tot concentricis, eccentricis, epicyclis, qui etsi in rerum natura non sint, nec in solido spacio concipi possint, motuum nihilominus caelestium rationes vere & infallibiliter demonstrant. Idem de Copernicani fystematis hypothesi iudicium esto. Verum vt quae hucusque dicta sunt, clarius intelligantur, & vt arti Magneticae nostrae melius applicentur, ea per aliquot Theoremata fusiùs deducenda existimaui; sit itaque

they can be demonstrated, which indeed is solidly represented, I suppose first, that it is the affection of two movable bodies, so that either one of the other, whether standing or moving around the globe, always results in the same face of the bodies, the same appearance according to the rules of Optics; for whether a motionless body be around me, or whether I move around a motionless body, the same position and position of the bodies must always result, and consequently the same appearance; so it is also in the same way, whether a roast is carried around the fire, or here around the roast, since the same is always the case with the roasting. the effect will be obtained: thus, in short, the same hour will be shown, whether the light is moved around a motionless clock, or whether the clock is moved around a motionless light, all of which is discussed above in Geometry. And we have shown our scientific astronomy; therefore it is difficult to argue the Copernican opinion from this chapter; Nevertheless, notwithstanding the affection of the aforesaid bodies, I say that he would act irrationally, who, when it is easier to obelisk someone's inscriptions, to go around, would command the obelisk to revolve around him; thus, in the opinion of all, he would be considered insane who, when he can easily tell the time from a motionless clock, would attempt to move the clock around the motionless Sun; so also the Copernicans are to be regarded as reckless Cyclops, who, neglecting the natural rest of the earth's thickest and most weighty body, with useless efforts, and with useless labor, turn it into uncertainty through the immense spaces of the heavens. the true body of the Sun, fiery and affecting motion by itself and by its own nature, they attach to the center of the universe. They themselves ought not to have regard to what Optics prescribed, but to what would be salutary to the preservation of bodies, if they wished to philosophize prudently. For he has many such mathematics, in which he concludes from falsities and impossibilities the true and most certain: Thus that divine Algebra produces something from nothing, while from smaller numbers nothing, from themselves falsities and impossibilities, leads to the solution of the most abstruse questions. Thus there are so many concentric, eccentric, and epicycles, which, although they do not exist in the natural world, nor can be conceived in solid space, nevertheless truly and infallibly demonstrate the principles of celestial motions. The same is true of the Copernican system hypothesis. It is true that what has been said up to this point may be more clearly understood, and that it may be better applied to our magnetic art. I considered them to be deduced by means of several Theorems fusiùs; so let it be

THEOREMA I. Sol eandem longitudinem iuxta eclypticam, eandem distantiam, & prostaphaeresin sortitur motu terrae, quam terrae statione.

I ponamus Terra circa Solem mundi centro affixum, in isto orbe D& motu commoueri, quo Sol secundum stantis Terrae hypothe¬ sim, conuersionem suam peragit, sequuntur iuxta huius Terrae motae hypothesin, eadem longitudo, distantia; eadem phaenomena con¬ sequuntur, quod ita ostendo: Sit Terra fixa in centro B Solis „νr BF talium partium 417. qualium semidiameter FA 10000. sit autem deferens Solis ADH, erit ergo perigaeum in H, apogaeum in A, hinc ponamus, Solem progressum in D punctum. Iterum ponatur Sol in centro Aimmotus, Terra verò mobilis in de¬ ferente suo BCE, eccentricati verò FB aequalis ponatur AG, erit igitur apogaeum terrae in A, perigaeum in E, progrediatur autem erra in suo deferente ex B vsque in C tantum, quantum Sol in priori

exemplo, ex A in D progres¬ sus statuebatur: quo posito connectantur AD, AC, CB, BD, DF, CG rectis lineis. Dico Solem fixum in A è terra mota B visum, eadem longi¬ tudine secundum eclypticam spectari, qua Sol motus ex A in D, ex terra immota B, quod ita demonstro: Cum enim ar¬

cus BC arcui AD aequalis po¬ natur, erit triangulum isopleu¬ ron FAD simile, & aequale triangulo isopleuro GCB, & angulus FAD aequalis angulo GCB, vel quod idem est BAD ipsi ABC aequalis. Erunt igi¬ tur duae aequales rectae AD, & BC parallelae, vti & rectae BD, & CA, quae illas conterminant, aequales erunt, & parallelae: quae cum ita sint: ergo Sol in cen tro A

immotus, è loco C terrae moto eodem loco videbitur, quo Sol mo¬ tus D ex terra in centro B quiescente, cum distantiae parallelae CA, & BD, vtpote terminantes parallelas BC, & AD, sint aequales. Praeterea Sol motus in D, ex terra stante B in eclyptica tantum pro¬ gressus videtur, quantum terra ex B in C promota, ex fixo Sole A spectatur, cum BD, CA parallelae sint, cumque lineae DF, & GC parallelae quoque sint, erunt eandem ob causam anguli prostaphae retici BDF, & ACG quoque aequales, vnde & consequenter prostaphaeresis (quae hinc demi debet) in vtraque hypothesi existit eadem, ergo Sol secundum terrae motae hypothesin apparentem lon¬ gitudinem in eclyptica, distantiam à terra, & prostaphaeresin habet eandem, quam terra immota, quod erat demonstrandum.

Consectarium I. EXhis sequitur, terram secundum motus sui hypothesin eodem tempore versari in sui deferentis BCE apogaeo E, quo So¬ lem in apogaeo A deferentis sui ADH: patet etiam terram in ec¬ centrici sui BCE semicirculo versari eodem tempore, Sole in semi¬ circulo eccentrici sui ADH consistente, sed & quàm longitudinem Sol in D habebit, eandem terra in C habebit, cum per supposi¬ tionem AD ipsi BC sit aequalis. Vnde & consequenter prosta¬ phaeresis vtriusque erit aequalis. Consectarium II.

AVm itaque Terra iuxta motus sui hypothesin similem semper „locum in suo deferente obtineat, quam Sol, fixa Terra in suo deferente, consequenter iuxta terrae fixae hypothesin eadem ex¬ ρorς, dierum aequatio, caeteraque id genus omnia, quaecumque iuxta stantis terrae hypothesin inueniri solent calculo, reperientur; quamuis multò totius naturae systemati (Terram stare, Solem verò moueri) magis congruum sit, & consentaneum.
