Now for the saluing of all the caelestiall Phaenomena, or appearances, the truth is the same, if wee suppose the earth to moue, as if wee beleeue it to stand still.  The riseing of the Sunne and Starres, the motions of all the Planets, will keepe Correspondence that now.  Nor neede wee feare logging, or that steples and towers would totter downe, for the motion is regular, and steady without rubbes, and knocks.  As if you turne a globe about, it will goe steadyly, and a fly will set fast vpon it, though you moue it apace.  Besides the whole body the ayre is carryed about with the whirlinge of the earth, so that the earth will make noe winde, as it turnes swiftly about; as a wheele will, if it bee turned apace.

Notwithstanding all this, most are of another opinion, that the earth standeth still without all motion, rest rather befittinge so heauy and dull a body then motion.  The maine reason brought to establish it is this.  Let a stone bee throwne downe out of the ayre from (W:) if the earth stand still, it is manifest it will fall vpon (X) iust vnder it; as wee see it doth by common experience, a stone will fall downe from any height vpon the place wee aymed at, but let the earth moue, the stone will not light vpon (X) but some where else as one (S:) for (X) will bee moued away, and gone to (V.)

So againe let two peices of ordinance that will shoote at equall distance bee discharged one iust towards the East, the other towards the West; if the earth moue (as they say it doth) towards the West, the bullet that is discharged Eastward will fly farther then that Westward.  For by the contrary motion of the earth hee will gaine ground.  But experience hath proued this to bee false, shewing that the bullets, will both fly at equall distance.

To salue this, answere is made that the earth by its swift motion carries with it and that steadily not only all bodies resting or moueing vpon it, but also the whole Sphaere of Aire (WEQ) with all things whatsoeuer that are moued in it naturally or violently, as clouds, birds, stones hurled vp or downe, arrowes, bullets, and such like things violently shott forth:  as may appeare in the figure.

The fourth rule.

4 The earth, though it bee of exceeding greate quantity being considered in itselfe, yet being compared to the Heauens, especially the higher sphaeres, is of noe notable bignes, but may be accounted as a point or pricke in the middest of the world.

That the earth is noe bigger then a point or pinns head in comparison of the highest heauens will easily appeare vnto vs, by these reasons.

1 The starres which are many times bigger then the earth, seeme yet to vs to bee noe bigger then a greate pinns head, or such like quantity; therefore much lesse shall the earth appeare to bee of any sensible magnitude.

2 Wee alwaies beholde halfe the heauens aboue vs, which could not bee if the earth had any sensible proportion to the heauen.
