    CHAP. HI. 7hat ihe Sun is the Center of the Vifible World. the following Chapters of this third. Book, it will evidently appear to every I cleer-fighted man,that what we ftiall here deliver concerning this point is nothing J[but truth, the firfl that entertain’d this opinion for reall,was iHvloiam } jih^gora^, whofe iudgment and dexterity of apprehenfion was moft exquilite, notwithftan- ding thofe brutiOi times wherein he lived, but after An i s i ot le had drawn the World to favour his fond conedts, this famous difeoverie of the truth became to be eclipfed, and fo continued for many Centuries of \ eares, yea even untill this laB age, when it pleafed God to raife up fome noble and hcroick wits to make an abfolute dif- covery, irifomuch that now this opinion is by gU our bell Mafters^of Agronomy, granted for no lelTe then truth , for as the continued obfervations of all Aftronomers in all ages, do perfpicuoufly prove the fame, fo is it molt proper that the © which is the mod worthy body of all the Planets,(hould retain the mod worthy place amongd them, which mud needs be acknowledged to be the Center, beddes if we do but con- fidcr, the Sphracall forme of the World (which you may difeerne by the former Sydeme) is it not then (I fay) mod proper, that the 0 (who is the onely giver both of light and heat to all the Planets round about him),bc in the Center? from whence^ he may bed difperfc the fame (by fending forth his Radiant beames) into all parts of the Circumference, which otherwife cannot fo well be done, were he placed in the Circumference, or any other point without it, but onely in the middle. And ladly, is it not mod certain that the two Planets 5 and ^ refped no other Center then the 0, and fo being placed within the Orbe of the Earth, towards the Center, they can never appear to us (in this middle Planet) neither to be^ in p, nor cP of the 0, and this was the main caufe that induced the Ancients to aflign them a mean motion e- qitall to that of the Sun, and refer the ina^quality or motion to thofe fidious Epicycles. The like may be faid of the other three primary Planets placed without the Orbe of of the Earth, though it be notfo percepcable to vulgar apprehenfions, andibr further proofe of this affertion infinite reafons Adronomicall m ight be given, but I P<tfle them by, hoping that the following Demondracion in this Booke, will be fufficient to evince the mod diffe opinion oppugnanc hereunto, therefore feeing the G is the Eye of the World, and very Fountain (it felf) of pure light, the Center doth of right mod fitly belong unto him, from whence (one every fide)he may diredly behold the . mod fixed concave of all the Planets and Stars with right angles. chap. IV. of the order of the other Sph^reS:. THere are feven Planets obfervable (befides the Concomitants of T> and U ) whofe Orbes are imaginarie Circles, whereon their glittering bodies move and wheel about, (as is deferibed in the Sydeme of the World.) Thofe we call primary Planets, whofe bodies move fimply about the 0, and thofe fe- condariePlanetswhichturnaboutthe primary Planets, whereby it comes to pafle, thatbefidestheirownpropermotionaboutthebody of their primar^^ Planet, they partici pa tealfo of the motion of the faid primary Planet, which moves about the 0. Ofthiskindly isobferved to have two fecondary Planets encompalfing his body, which ty help oftheTelekope, are found to be fometime neer, and fometime fur¬ ther remote from him* In ^ is obferved four Stars of like kinde, which wheel about his body, as their proper Center, the fird is didant from him to the fight about 6 Se¬ midiameters of the Earth, the fecond 8, the third lo, and the fourth fome twenty.
