Rohonc Codex

The Rohonc Codex is a book that was made a long time ago (about 200 years ago) and nobody knows who wrote it or what it says. People have been trying to figure it out for a long time, but they haven't been able to because it is written in a language that nobody knows.

The book is made of paper, and it is very old and fragile. It has lots of drawings and symbols in it, and some people think that it might contain a secret code or hidden message.

But nobody has been able to solve the mystery of the Rohonc Codex yet. It remains one of the greatest unsolved puzzles in the world, and people from all over the world are still trying to figure out what it means.
