"The earth which is the visible, natural basis of it represents the gross, carnal parts. The element of water answers to the blood, for in it the pulse of the Great World beats: this most men call the flux and reflux, but they know not the true cause of it. The air is the outward refreshing spirit, where this vast creature breathes though invisibly, yet not altogether insensibly."
