and this (say they) is the reason, why in the Sunnes eclipses, the spots and brighter parts are still in some measure distinguished, because the Sunne beames are not able so well to penetrate through those thicker, as they may through the thinner parts of the Planet. Of this opinion also was Cæsar la Galla, whose words are these,[1] "The Moone doth there appeare clearest, where shee is transpicuous, not onely through the superficies, but the substance also, and there she seemes spotted, where her body is most opacous." The ground of this his assertion was, because hee thought the Moone did receive and bestow her light by illumination onely, and not at all by reflexion, but this, together with the supposed penetration of the Sunne beames, and the perspicuity of the Moones body I have above answered and refuted.
- ↑ Ex qua parte luna est transpicua non solum secundum superficiem, sed etiam secundum substantiam, catenus clara, ex qua autem parte opaca est, eatenus obscura videtur.
