On the Making of Man
“This is the book of the generation of heaven and earth ,” saith the Scripture, when all that is seen was finished, and each of the things that are betook itself to its own separate place, when the body of heaven compassed all things round, and those bodies which are heavy and of downward tendency, the earth and the water, holding each other in, took the middle place of the universe; while, as a sort of bond and stability for the things that were made, the Divine power and skill was implanted in the growth of things, guiding all things with the reins of a double operation (for it was by rest and motion that it devised the genesis of the things that were not, and the continuance of the things that are), driving around, about the heavy and changeless element contributed by the creation that does not move, as about some fixed path, the exceedingly rapid motion of the sphere, like a wheel, and preserving the indissolubility of both by their mutual action, as the circling substance by its rapid motion compresses the compact body of the earth round about, while that which is firm and unyielding, by reason of its unchanging fixedness, continually augments the whirling motion of those things which revolve round it, and intensity is produced in equal measure in each of the natures which thus differ in their operation, in the stationary nature, I mean, and in the mobile revolution; for neither is the earth shifted from its own base, nor does the heaven ever relax in its vehemence, or slacken its motion.
