How do I get past Zeus?

Have you read what he has said, very carefully?

This is one of the toughest puzzles in the game.

Do you have the rod of luck?

It's not enough.  Plain and simple.  You need to change the laws
of the universe.

Have you found the rod of bronze?

Good.  I hope you have a saved game, before you entered the Maiden?

You need to do some work back in the gardens.

What was it that first led you the green quarterstaff (bronze rod)?

The mural.  What is the mural made of?

Bronze, a rod of bronze a bronze mural.  Worth a try, huh?

Strike, and point the rod of bronze at the mural to open a passage.

If you go south from the jagged passage.  You find a room with a smell.
The room name is the Catacombs. There is only a small reference in the
text about the smell, so look curses
carefully.

Smell.  What is that?  Better check again.

Smell.  And you discover another previous hidden passage.

Go Down.  Ah, the Universe Maintenance Room.

Don't turn the dial.  At least if you want to live.

Turn off the switch.  Now Determinism is no longer a factor.
