2. There is no element of fire, which must be held with this opinion here delivered; for if wee suppose a world in the Moone, then it will follow, that the spheare of fire, either is not there where ’tis usually placed in the concavity of his Orbe, or else that there is no such thing at all, which is most probable, since there are not any such solid Orbs, that by their swift motion might heare and enkindle the adjoyning aire, which is imagined to be the reason of that element. Concerning this see _Cardan_, _Iohannes Pena_ that learned _Frenchman_, the noble _Tycho_, with divers others who have purposely handled this proposition. 3. I might adde a third, _viz._ that there is no Musicke of the spheares, for if they be not solid, how can their motion cause any such sound as is conceived? I doe the rather medle with this, because _Plutarch_ speaks as if a man might very conveniently heare that harmony, if he were an inhabitant in the Moone. But I guesse that hee said this out of incogitancy, and did not well consider those necessary consequences which depended upon his opinion. However the world would have no great losse in being deprived of this Musicke, unlesse at some times we had the priviledge to heare it: Then indeede _Philo_ the Jew[1] thinkes it would save us the charges of diet, and we might live at an easie rate by feeding at the eare onely, and receiving no other nourishment; and for this very reason (saies he) was _Moses_ enabled to tarry forty daies and forty nights in the Mount without eating any thing, because he there heard the melody of the Heavens,--_Risum teneatis_. I know this Musicke hath had great patrons both sacred and prophane authours, such as _Ambrose_, _Bede_, _Boetius_, _Anselme_, _Plato_, _Cicero_ and others, but because it is not now, I thinke affirmed by any, I shall not therefore bestow either paines or time in arguing against it. [Sidenote 1: _De somniis._] It may suffice that I have onely named these three last, and for the two more necessary, have referred the Reader to others for satisfaction. I shall in the next place proceede to the nature of the Moones body, to know whether that be capable of any such conditions, as may make it possible to be inhabited, and what those qualities are wherein it more neerely agrees with our earth. Proposition 4. _That the Moone is a solid, compacted, opacous body._ I shall not need to stand long in the proofe of this proposition, since it is a truth already agreed on by the generall consent of the most and the best Philosophers. 1. It is solid in opposition to fluid, as is the ayre, for how otherwise could it beare backe the light which it receives from the Sunne?
