Qu. 13. Do not several sorts of Rays make Vibrations of several bignesses, which according to their bigness excite Sensations of several Colours, much after the manner that the Vibrations of the Air, according to their several bignesses excite Sensations of several Sounds? And particularly do not the most refrangible Rays excite the shortest Vibrations for making a Sensation of deep violet, the least refrangible the largest form making a Sensation of deep red, and several intermediate sorts of Rays, Vibrations of several intermediate bignesses to make Sensations of several intermediate Colours?

Henceforward the Christian Churches having a form of godliness, but denying the power thereof, came into the hands of the Encratites: and the Heathens, who in the fourth century came over in great numbers to the Christians, embraced more readily this sort of Christianity, as having a greater affinity with their old superstitions, than that of the sincere Christians; who by the lamps of the seven Churches of Asia, and not by the lamps of the Monasteries, had illuminated the Church Catholic during the three first centuries.

Now in this vision of the Image composed of four Metals, the foundation of all Daniel's Prophecies is laid. It represents a body of four great nations, which should reign over the earth successively, viz. the people of Babylonia, the Persians, the Greeks, and the Romans. And by a stone cut out without hands, which fell upon the feet of the Image, and brake all the four Metals to pieces, and became a great mountain, and filled the whole earth; it further represents that a new kingdom should arise, after the four, and conquer all those nations, and grow very great, and last to the end of all ages.
