Pillar 4

Pillar 4 during daytime

Pillar 4 contains a non-alphanumeric cipher with dots connected with etched lines forming constellation-like shapes (Not transcribed and Unsolved), a long string of letters forming a scytale input (Partly Solved) and a series of numbers around the bottom which probably form part of a cipher (Unsolved). Between the constellation grid and string of letters is an octagonal section in the pillar representing a scytale.

Constellation grid

Example of "constellation" writing

The top cipher is a grid of Chappe Semaphore representations.

Transcribed by neonsignal, using the following methodology: The first digit is the leftmost flag, the second digit is the rightmost flag. The number represents the rotation angle of the flag clockwise around the arm, beginning from the centre of the glyph (1=45°, 2=90°, 3=135°, 4=225°, 5=270°, 6=315°).

Or the alternative transcription effort by Bob Dovenberg, noting " Each "node" can be in one of six positions (the right number is listed first). Each combination of positions represents a letter. There is a pattern to the "flow" through the alphabet."

And decoded by Bob Dovenberg on 17 March to read:

Scytale - Solved

The pillar contains an octagonal section above a long string of letters written vertically in a long strip. At either end of the long strip, dividing lines create three separated sections. In the transcription, these are represented with a space.

A MESSAGE HID UPON HIS SLAVE SHOWN TO ALL BY CLOSER SHAVE AN ADMIRAL OF ANCIENT GREECE UNCERTAIN OF A PERSIAN PEACE SAW A CODE THAT PROVED MUCH SMARTER HELPED ENSURE HIS WIN FOR SPARTA

The code talks about the use of tattooing messages in hidden locations (namely a shaved head, then allowing the hair to regrow) by Histiaeus. The history of the scytale is alluded to as being much smarter (and presumably a lot quicker, since one does not need to wait for hair to regrow).

Stuart Kohlhagen reported on Facebook that simply decoding the scytale component does not 'solve' the code and that further work is required.
