Underneath the Vatican, you'll find a tomb with ten skeletons guarding it. If you follow this guide closely, you'll be able to solve the mystery and open the tomb. By opening it, you'll receive the jawbone of a donkey, the same one that Samson used to kill 1,000 Philistines (Judges 15:15).

To open the tomb, you need to take a closer look at the skeletons. Each skeleton has a number above its head - ten numbers for ten skeletons.

The mystery is linked to the Secret of Giants quest, in which you have to take a total of ten photos of the ten inscriptions found throughout the Vatican. If you take a closer look at these photos, you'll see that some of the inscriptions have candles engraved on them. The order of the photos shows you which lights you need to illuminate on each of the skeletons at the tomb.

Essentially, this means that you have to illuminate the lights in the following order to open the tomb and solve the mystery: 1, 3, 4, 6, 7, 10.



And that's all you need to do to solve this mystery. The jawbone is exceptionally durable, but unfortunately, Indiana Jones can't carry any additional weapons besides his own. Therefore, I recommend putting the weapon back in a safe place after use, so you can easily find it again later if you wish to retrieve it at another time.
