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.
