How to Solve the Secret of Secrets in Indiana Jones and the Great Circle

The Secret of Secrets can be found in the Sistine Chapel’s back room in the Vatican City chapter. Players will find a safe on a desk, and beside it, there will be a Note to collect: Nicoletti’s Letter.

The letter itself details the clues that players need to solve this puzzle, as it asks players to “look to the stars and the saints: Peter with the key, then Paul with the sword.”

Players need to head to the right of the safe to find the Saint Peter wooden statuette, noted by how he holds a key. They can then inspect and rotate this item once they pick it up to view the underside of the statue, which will have two symbols etched underneath in white paint. The two symbols underneath should be the Astronomical Symbols for Mars x2. (4, 4)

Next, players will want to head back to the safe where they can find the wooden statuette of Saint Paul, as noted by his sword holding. Collect this item and inspect it, viewing the underside of it to reveal two more symbols: Uranus and Merkur. (7, 1)

Within the desk opposite the safe, players can open the drawer on the left to reveal the Planetary Chart note, which details the Astronomical symbols of all planets except Pluto. Starting from Merkur (bottom of the page), the planets are listed from 1 to 8, with the only missing symbol being that of Mars, which is 4.

Now that players have the note to translate the astronomical symbols underneath the statues, it’s time to put in the correct code into the safe.
