and many others.
But now this could not be,
if that Light were her own, that being con-
ſtantly the ſame, and without any Reaſon of
ſuch an Alteration:
So that thus I may argue.
If there were any Light proper to the Moon,
then would that Planet appear Brighteſt when
ſhe is Eclipſed in her Perige being neareſt to
to the Earth, and ſo conſequently more Ob-
ſcure and Duskiſh when ſhe is in her Apoge,
or fartheſt from it;
the Reaſon is, becauſe the
nearer any Enlightned Body comes to the
Sight, by ſo much the more ſtrong are the
Species, and the better perceiv'd.
This Se-
quel is granted by ſome of our Adverſaries,
and they are the very Words of Noble Tycho,

If the Moon had any Light of her own,
then ſhe would not loſe it in the Earths Sha-
dow, but rather ſhine more Clearly, ſince eve-

it is not hindred by a more perſpicuous Bright-

(as Obſervation doth manifeſt, and our Op-
poſites themſelves do grant) the Moon appea-
ring with a more reddiſh and clear Light when
ſhe is Eclipſed, being in her Apoge or fartheſt
diſtance, and a more blackiſh Iron Colour
when ſhe is in her Perige, or neareſt to us,
therefore ſhe hath not any Light of her own.
