The Instructions of Commodianus 4

And Saturn the old, if he is a god, how does he grow old? Or if he was a god, why was he driven by his terrors to devour his children? But because he was not a god, he consumed the bowels of his sons in a monstrous madness. He was a king upon earth, born in the mount Olympus; and he was not divine, but called himself a god. He fell into weakness of mind, and swallowed a stone for his son. Thus he became a god; of late he is called Jupiter.
