The discovery of a world in the moone : $b or, A discovrse tending to prove that 'tis probable there may be another habitable world in that planet

Before I proceede to the next Position, I shall first answer some doubts
which might be made against the generality of this truth, whereby it may
seeme impossible that there should be either Sea or Land in the Moone;
for since she moves so swiftly as Astronomers observe, why then does
there nothing fall from her, or why doth shee not shake something out by
the celerity of her revolution? I answer, you must know that the
inclination of every heavie body, to its proper Center doth sufficiently
tie it unto its place, so that suppose any thing were separated, yet
must it necessarily returne againe, and there is no more danger of their
falling into our world then there is feare of our falling into the
Moone.
But yet there are many fabulous relations of such things as have dropped
thence. There is a tale of the Nemean Lyon that _Hercules_ slew, which
first rushing among the heards out of his unknowne den in the Mountaine
of _Cytheron_ in _Bœotia_, the credulous people thought he was sent from
their Goddesse the Moone. And if a whirle-winde did chance to snatch any
thing up, and afterwards raine it downe againe, the ignorant multitude
are apt to believe that it dropt from Heaven. Thus _Avicenna_ relates
the story of a Calfe which fell downe in a storme, the beholders
thinking it a Moone-calfe, and that it fell thence. So _Cardan_
travelling upon the Apennine Mountaines, a sudden blast tooke off his
hat, which if it had beene carryed farre, he thinkes the peasants who
had perceived it to fall, would have sworne it had rained hats. After
some such manner many of our prodigies come to passe, and the people are
willing to believe anything, which they may relate to others as a very
strange and wonderfull event. I doubt not but the Trojan _Palladium_,
the Romane _Minerva_, and our Ladies Church at _Loretto_, with many
sacred reliques preserved by the Papists might droppe from the Moone as
well as any of these.
But it may be againe objected, suppose there were a bullet shot up in
that world, would not the Moone runne away from it, before it could fall
downe, since the motion of her body (being every day round our earth) is
farre swifter than the other, and so the bullet must be left behinde,
and at length fall downe to us? To this I answer,
1. If a bullet could be shot so farre till it came to the circumference
of those things which belong to our center, then it would fall downe to
us.
2. Though there were some heavie body a great height in that ayer, yet
would the motion of its centre by an attractive vertue still hold it
within its convenient distance, so that whether their earth moved or
stood still, yet would the same violence cast a body from it equally
farre. That I may the plainer expresse my meaning, I will set downe this
Diagramme.
