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.
3 All obseruations of hights and distances of the coelestiall
bodies, which are made on the superficies of the earth, are as
exact, and true, as if they were made in the very center of the
earth. Which were impossible, vnlesse the thicknes of the earth
were insensible in regard of the Heauens.
4 All Sunn Dialls which stand on the superficies of the earth,
doe as truely cast the shadowes of the houres, as if they stood
in the Center. As for example.
