You may see this truth assented unto by _Blancanus_ the Jesuit,[3] and by him confirmed with with divers reasons. _Keplar_ hath observed in the Moones eclipses,[4] that the division of her enlightened part from the shaded, was made by a crooked unequall line, of which there cannot be any probable cause conceived, unlesse it did arise from the ruggednesse of that planet, for it cannot at all be produc’d from the shade of any mountains here upon earth, because these would be so lessned before they could reach so high in a conicall shadow, that they would not be at all sensible unto us (as might easily be demonstrated) nor can it be conceived what reason of this difference there should be in the Sunne. Wherefore there being no other body that hath any thing to doe in eclipses, we must necessarily conclude, that it is caused by a variety of parts in the Moone it selfe, and what can there be but its gibbosities? Now if you should aske a reason why there should be such a similitude of these in that Planet, the same _Keplar_ shall jest you out an answere, for supposing (saith he) those inhabitants are bigger than any of us in the same proportion, as their daies are longer than ours, viz. by fifteen times it may bee for want of stones to erect such vast houses as were requisite for their bodies, they are faine to digge great and round hollowes in the earth, where they may both procure water for their thirst, and turning about with the shade, may avoid those great heats which otherwise they would be lyable unto; or if you will give _Cæsar la Galla_ leave to guesse in the same manner, he would rather think that those thirsty nations cast up so many and so great heaps of earth in digging of their wine cellars, but this onely by the way.
