But they who contend that these things never happened, but are only figures setting forth other things, in the first place suppose that there could not be a flood so great that the water should rise fifteen cubits above the highest mountains, because it is said that clouds cannot rise above the top of Mount Olympus, because it reaches the sky where there is none of that thicker atmosphere in which winds, clouds, and rains have their origin. They do not reflect that the densest element of all, earth, can exist there; or perhaps they deny that the top of the mountain is earth. Why, then, do these measurers and weighers of the elements contend that earth can be raised to those aerial altitudes, and that water cannot, while they admit that water is lighter, and liker to ascend than earth? What reason do they adduce why earth, the heavier and lower element, has for so many ages scaled to the tranquil æther, while water, the lighter, and more likely to ascend, is not suffered to do the same even for a brief space of time?
