also, that in time, the _shadow_ of _Saturns Moon_ will be seen upon _Saturn_, although we are yet some years to stay for it, and to prepare also for better Glasses. From this rare Observation, he inferrs the _Proportion_ of the _Diameter_ of the _Satellites_ to that of _Jupiter_; and judgeth, that no longer doubt can be made of the turning of these 4. _Satellites_, or _Moons_ about _Jupiter_, as our _Moon_ turns about the _Earth_, and after the same way as the rest of the Celestial Bodies of our _Systeme_ do move: whence also a strong conjecture may be made, that _Saturns_ Moon turns likewise about _Saturn_. Hence he also taketh occasion to intimate, that we need not scruple to conclude, that if these two _Planets_ have _Moons_ wheeling about them, as our _Earth_ hath one that moves about it, the conformity of these _Moons_ with our _Moon_, does prove the conformity of our _Earth_ with those _Planets_, which carrying away their _Moons_ with themselves, do turn about the _Sun_, and very probably make their _Moons_ turn about them in turning themselves about their _Axis_; and also, that there is no cause to invent perplex'd and incredible _Hypotheses_, for the receding from this _Analogie_ since (saith he) if this be truth, the Prohibitions of publishing this doctrine, which formerly were caused by the offence of Novelty, will be laid aside, as one of the most zealous Doctors of the contrary Opinion hath given cause to hope, witness _Eustachius de Divinis_, in his _Tract_ against Monsieur _Hugen_'s _Systeme_ of _Saturn_, _p._ 49. where we are inform'd, that that learned Jesuit, _P. Fabry_, Penitentiary of S _Peter_ in _Rome_, speaks to this purpose: Ex vestris, iisque Coryphaeis non semel quaesitum est, utrum aliquam haberent demonstrationem pro _Terrae motu_ adstruendo. Nunquam ausi sunt id asserere Nul igitur obstat quin loca illa in sensu literali Ecclesia intelligat, & intelligenda esse declaret, quamdiu nulla demonstratione contrarium evincitur; quae si forte aliquando a vobis excogitetur (quod vix crediderim) in hoc casu nullo modo dubitabit Ecclesia declarare, loca illa in sensu figurato & improprio intelligenda esse, ut illud Poetae, _Terraeque Urbesque recedunt_. _It hath been more than once asked of your Chieftains, whether they had a Demonstration for asserting the motion of the Earth? They durst never yet affirm they had; wherefore nothing hinders, but that the Church may understand those Scripture-places, that speak of this matter, in a _literal_ sence, and declare they should be so understood, as long as the contrary is not evinced by any demonstration; {75} which, if perhaps it should be found out by you (which I can hardly believe it wil) in this case the Church will not at all scruple to declare, that these places are to be understood in a figurative and improper sence, according to that of the Poet, _Terraeque Urbesque recedunt_._
