A son battles his father for control of the universe. And seizes more power than any god ever had. This is the story of Zeus, Greek mythology's supreme commander. To us it's a myth, but to the ancients, it was reality. A way to make sense of a terrifying world. Some Greeks believed Zeus was the one true god centuries before Christ. And that nature's worst catastrophes were the sign of his wrath. This is the myth of Zeus as it was originally told. And the surprising truth behind it.
