Young was the world when Sargon built Babylon some five thousand years ago, long did it grow and prosper, gaining its first empire the eighteenth century BC, under godlike Hammurabi, the giver of law. Although conquered by the Kassites and then by the Assyrians, Babylon endured, emerging phoenix-like from its ashes of destruction and regaining its independence despite its many enemies. Truly was Babylon the center of arts and learning in the ancient world. O Nebuchadnezzar, your empire endured but a short time after your death, falling to the mighty Persians, and then to the Greeks, until the great city was destroyed by 141 BC.",
