Deep within the catacombs of Rome, we discovered a secret entrance into the catacombs beneath Vatican City. Upon further exploration, we discovered a great vault. On the massive door of the vault is depicted a man worshiping an angel. Additionally, on the door is a keypad prompting for a five digit pass-code.

Given the nature of the vault, we suspect it to contain first-class relics of the Roman Catholic Church. A trusted informant serving in the Papal Apartments has delivered a message to us which he says contains the five digit code to get into the vault. It is as follows:

2504 2491 3588 191 2532 991 3778 2532 3753 191 2532 4098 4352 1715 3588 4228 3588 32 3588 1166 1473 3778

Can you decipher the message to find the code and open the vault?

What do we find inside the vault?


The body of the riddle contains the answer to the second question, speculation is unnecessary.

1 Answer 1


Partial Answer

The message in encrypted by Strong's Greek Dictionary(https://greeklexicon.org/)

Now coming to message.

I ABCD, hear and see this and when heard and fall down and kneel before the foot of angels, those showed me this.

Here ABCD can be Joannes(90%), John: the Baptist, John: the Apostle, John Mark.

Thanks to @Stiv and @JS1 The text is taken from Revelation 22:8.(https://biblehub.com/revelation/22-8.htm). Reading the whole chapter 22 reveals something about the scroll and it could be a first-class relic as it is directly related to Jesus.

The Code(thanks to @JS1),

66228 Reason- Revelation is the 66th book of Bible. And the text is taken from Revelation 22 verse 8.

What will we find inside the vault?,

not quite sure yet. I guess it's some scroll(again thanks to @JS1).

  • $\begingroup$ (A) How did you think of trying this?? Impressive. B) These words bear a striking resemblance to rot13(Eriryngvba puncgre 22 irefr 8) - maybe head there next for further inspiration...? $\endgroup$

  • $\begingroup$ @Stiv A) In my second attempt to solve it, I just used a simple strategy. Copy pasted the entire code on Google.😂. After 2-3 hours of research, 95% of results were on Lexicon Bible. Then I studied more about that, discovered Strong's Greek Dictionary. Used it and now I am here. B) I have never read Bible. So, I will have to do some research. $\endgroup$

  • $\begingroup$ Sure you can answer what I commented although I'm not 100% sure it is correct. I'm trying to help you solve the rest of this, as you figured out the main part, and I am not going to post any answer myself. As for what is inside the vault, rot13(Eriryngvbaf 22:7-10 gnyxf nobhg n fpebyy, znlor gung vf vg?) $\endgroup$
