SIMPL. Amongſt the reſemblances by you recited, in the
rallel
you make betwixt the Earth and Moon, I find that I can
admit
none confidently ſave onely the firſt, and two others; I
grant
the firſt, namely, the ſpherical figure; howbeit, even in
this
there is ſome kind of difference, for that I hold that of the
Moon
to be very ſmooth and even, as a looking-glaſſe,
as
, we find and feel this of the Earth to be extraordinary
ous
and rugged; but this belonging to the inequality of
cies
, it ſhall be anon conſidered, in another of thoſe
ces
by you alledged; I ſhall therefore reſerve what I have to ſay
thereof
, till I come to the conſideration of that.
Of what you
affirm
next, that the Moon ſeemeth, as you ſay in your ſecond
Reſemblance
, opacous and obſcure in its ſelf, like the Earth; I
admit
not any more than the firſt attribute of opacity, of which
the
Eclipſes of the Sun aſſure me.
For were the Moon
rent
, the air in the total obſcuration of the Sun, would not
come
ſo duskiſh, as at ſuch a time it is, but by means of the
tranſparency
of the body of the Moon, a refracted light would
paſſe
through it, as we ſee it doth through the thickeſt clouds.
But
as
to the obſcurity, I believe not that the Moon is wholly
ved
of light, as the Earth; nay, that clarity which is ſeen in the
remainder
of its Diſcus, over and above the ſmall creſcent
lightened
by the Sun, I repute to be its proper and natural light,

and
not a reflection of the Earth, which I eſteem unable, by
reaſon
of its aſperity (craggineſſe) and obſcurity, to reflect the
raies
of the Sun.
In the third Parallel I aſſent unto you in one

part
, and diſſent in another: I agree in judging the body of the
Moon
to be moſt ſolid and hard, like the Earth, yea much more;

for
if from Ariſtotle we receive that the Heavens are impenetrable,
and
the Stars the moſt denſe parts of Heaven, it muſt neceſſarily
follow
, that they are moſt ſolid and moſt impenetrable.
The ſubſtance of
the
Heavens
netrable
,
ing
to Ariſtotle.
