Daniel 2:32

And so how can we not consider the ancient things which were prophesied by Daniel in Babylon and are now still being fulfilled in the world? For the image which was portrayed according to that season, embraced the model of the kingdom of all the world. In which season the Babylonians then reigned, as being the golden head of the image. Then after them the Persians ruled for two hundred forty-five years as they are shown to be silver. After them the Greeks ruled, beginning from Alexander of Macedon, for three hundred years, as they are bronze. After them the Romans, who are the iron legs of the image, being strong as iron. Next the toes of the feet, so that in each place democracies are shown, which are destined to be and which are divided into the ten toes of the image, in which the iron will have been mixed with clay.

"Thou sawest," etc. Apollinaris on this: He looked, and behold, as it were, an image. For it did not appear to him as an actual object, presented to the view of an onlooker, but as an image or semblance. And while it contains in it many things together, that is in such a way that it is not really one, but manifold. For it comprised a summary of all kingdoms; and its exceeding splendour was on account of the glory of the kings, and its terrible appearance on account of their power. Eusebius Pumphili, and Hippolytus the most holy bishop of Rome, compare the dream of Nebuchadnezzar now in question with the vision of the prophet Daniel. Since these have given a different interpretation of this vision now before us in their expositions, I deemed it necessary to transcribe what is said by Eusebius of Caesarea, who bears the surname Pamphili, in the 15th book of his Gospel Demonstration; for he expounds the whole vision in these terms: "I think that this (i.e., the vision of Nebuchadnezzar) differs in nothing from the vision of the prophet. For as the prophet saw a great sea, so the king saw a great image. And again, as the prophet saw four beasts, which he interpreted as four kingdoms, so the king was given to understand four kingdoms under the gold, and silver, and brass, and iron. And again, as the prophet saw the division of the ten horns of the last beast, and three horns broken by one; so the king, in like manner, saw in the extremities of the image one part iron and another clay. And besides this, as the prophet, after the vision of the four kingdoms, saw the Son of man receive dominion, and power, and a kingdom; so also the king thought he saw a stone smite the whole image, and become a great mountain and fill the sea. And rightly so. […]

The second element, silver, signifies the Persian kingdom and the Medes. Cyrus, by way of his own success and marriage, created from the Medes the kingdom of Persia.… He speaks of a chest and arms to show that he knows there were two peoples, each …

In all events Scripture says, "You, O king, were looking, and behold, one image: Great was that image and its appearance was fearful. The head of the image was of pure gold, its hands and chest and its arms were silver, the stomach and thighs were bronze, its legs were iron, the feet were part iron, part clay. You were looking until you saw a stone, which was cut without hands and it struck the image at the iron and clay feet and crushed it completely. Then once for all, the clay, iron, bronze, silver and gold were ground and they became like chaff from the summer threshing floor. And the greatness of the wind carried them away and no place was found for them. And the stone which struck the image became a great mountain and it filled all the earth. This is the dream and we will tell its interpretation before the king. You, O king, are the king of kings, to whom the God of heaven has given a strong, mighty, and honorable kingdom in every place where the sons of men dwell, and he has given into your hand beasts of the field and birds of heaven and he has ordained you Lord of all. You are the head of gold. And after you another kingdom shall arise, which is lesser than you. And a third kingdom shall arise which is bronze, which shall rule over all the earth. And a fourth kingdom will be strong as iron. In the way which iron grinds and subdues all, in this way it will grind and subdue all. And because you saw the feet and the toes, part of which were iron, part of which were clay, the kingdom shall be divided, and in it there shall be from the nature of iron, in which manner, you saw iron mixed with clay.

This is the kingdom of the children of Javan, who are children of Japhet. For the children of Javan came against the kingdom of their brothers. For Madai and Javan are sons of Japhet. But Madai was foolish and incapable of governing the kingdom, until Javan, his brother, came, who was wise and cunning, to destroy the kingdoms. For Alexander, son of Philip, ruled in all the earth.
