Pillar 4 contains three ciphers: at the top, a grid of "constellations" of dots joined by lines; a long string of letters winding around the pole; and the ubiquitous numbers around the base. Between the constellation grid and string of letters is an octagonal section in the pillar.
The top cipher is a grid of non-alphanumeric glyphs that resemble constellations.
To be transcribed (after a method is identified) and photos compiled. See the image gallery in the interim.
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.
