Hercules: The Legendary Journeys - Season 3 Episode 18 -

King Augeus had gone mad. Believing himself Zeus, the King ordered Aphrodite's temple to be rededicated to Hera. The evil goddess herself offered Augeus godly powers if he could kill Hercules by sunset. Aphrodite, angered by the king's actions, stepped in to reclaim her temples and protect the townspeople. Augeus - assisted by Hera - managed to imprison Aphrodite briefly, but the goddess joined forces with Hercules and battled the king until his delusion lifted. Augeus wasn't quite back to normal, however: Now he believed he was Ulysses.
