Reading books may sometimes be very profitable! While you were idly turning over the pages of "The History of the Ancient World" encyclopedia, a little sheet of paper slipped out of it.

Your amazement had no limits when you understood it was a real treasure map! Of course, you departed immediately.

But when you were standing on the place which in the map was marked with a thick red cross, you saw a big rock in front of you and nothing more.

Looking at it in despair, you've discerned some strange signs scratched on the rock...It's just a riddle that you are to solve to reach the treasure!
