The Destruction of the Great Confederacy

In about 584BC, Nebuchadnezzar II, the king of the Babylonian Empire, had a strange dream, recorded in Daniel ch2. He saw a metallic image, whose golden head, we are informed, represented his own great kingdom (v38). The silver breast and arms, and the brazen belly and thighs represented the empires that would follow on (v39). These are named explicitly, in Dan 8v20, 21, as the Medo-Persian and the Greek empires, respectively.
