But they doe alwaies in their mutuall vicssitudes participate of one anothers light; so also doe they partake of the same defects and darknings, for when our Moone is eclipsed, then is their Sunne darkened, and when our Sunne is eclipsed, then is their Moone deprived of its light, as you may see affirmed by Mæslin.[2] Quod si terram nobis ex alto liceret intueri, quomadmodum deficientem lunam ex longinquo spectare possumus, videremus tempere eclipsis solis terræ
