Hello from Spain
I have a good solution for the last message of the sculpture, but I have not used a code. I've only used the art of deduction according to the clues left by the sculptor
According to Occam's razor, the simplest solution to the mystery of the fourth and final message of the sculpture is this:
iF Letters 64-69 "NYPVTT" = "BERLIN" then K4 can be:
".....PEOPLE TO CREATE A SAFER FREER WORLD AND SURELY THERE IS NO BETTER PLACE THAN BERLIN THE MEETING PLACE OF EAST AND WEST."
— By Ronald Reagan, address at the Brandenburg Gate, June 12, 1987.
Because if K4 is a real text (like K3), then i should find key phrases/quotes related to Berlin (place). I look for the most important and beautiful texts (Kennedy & Reagan speeches)
And here I found this fragment: http://www.americanrhetoric.com/speeches/ronaldreaganbrandenburggate.htm
He said: “Today, thus, represents a moment of hope …….PEOPLE TO CREATE A SAFER, FREER WORLD AND SURELY THERE IS NO BETTER PLACE THAN BERLIN THE MEETING PLACE OF EAST AND WEST, to make a start.”
SO, if K 3 has a question: ” …… can you see anythyngq?“. (The account of Howard Carter, the renowned Egyptologist, as he opened King Tut’stomb. --and breaking the WALL--) THEN K 4 has an beatiful answer “ People to create a safer, freer world ……..” ( Reagan speech at the Berlin WALL)
This is a very nice/lovely solution but I have not a mathematical explanation.
Maybe you can help me to solve the last problem: THE CODE.
Bye
