Daniel explained the statue's head of gold stood for Nebuchadnezzar’s kingdom. (Neo-Babylon ruled the world from 612 to 539 BC). According to the Hebrew, the statue's chest and arms of silver represented Medo-Persia. (This was to become the next dominant world power from 539 to 331 BC).
The belly and thighs of brass stood for another great power, Greece, which was to rule from 331 to 168 BC. Then the statue's iron legs were described as symbolizing Rome, the empire that conquered the Greeks in 168 BC and dominated world affairs with an iron will until its fall in 476 AD.
The statue also had feet made of iron and clay (representing the divided kingdoms of Europe that have never achieved unity.) At the end of the dream a rock, symbolizing God's everlasting kingdom, destroyed the statue and proceeded to endure forever.
Thanks to Daniel's success at explaining to King Nebuchadnezzar his dream and its meaning, all the wise men were spared. Daniel made a deep impression on the Babylonian ruler who promoted him to the position of governor of the entire province of Babylon.
