We examine the cover drawing of the Palenque sarcophagus lid in this document.
Our supposition is that it could contain a hidden message encoded in its pattern.
We try to decipher the code and reveal this secret message in 12 steps.
In step #1 we recognize that the pattern can be divided into two parts and the upper section is a square:
In step #2, first we notice the two plain X shapes on the edges:
Then we realize that we can bring the two X shapes to cover each other by duplicating the pattern and rotating the second layer 90° clockwise:
In step #3 we try to find out, what could be the context for the secret message that is (presumably) encoded in the configuration of the triplets.
First, we recognize the left face-like shape as a potential diagram of the Solar System:
In step #4 we create a normalized version of the pattern by placing the relevant items in a coordinate system:
Note: about the item #6 (whether it should be treated as a triplet or not), please refer here.
In step #5 we perform the three rotations again in this system:
In step #6 we realize that we can make the pattern more complete by reflecting it in the Y axis (this is the finish of the pattern-level transformation phase):
In step #7 we analyze the obtained pattern:
We conclude that its symmetry is not barely the result of the rotations, but instead the items must have been placed in a (very) special way initially by the designers to obtain such an ordered arrangement.
In step #8, first we have to find the new, item-level transformation method that is required to continue the solution (since the picture cannot be made more perfect at the pattern-level any longer):
In step #9, first we remove the corner elements, following the hint of the inner shape:
In step #10, first we notice that apparently the inner and outer squares should be attached to each other:
In step #11 we try to interpret this picture and to locate the other solar system with the help of it.
First, we remove the redundant items, then we integrate the closing part of the other star symbols into the drawing:
We conclude that the squares between the Sun and the two stars most probably represent the (relative) distances from the nearest star (the Proxima Centauri):
The other solar system, which served as the starting point for the interstellar travel, consists of two stars (i.e. is a binary system), and is approximately three times as far away from us, as the nearest star (the Proxima Centauri).
Finally, in step #12 we review the process and analyze the encoding method.
