John Kelly Tablet
- The following link shows primary site documents from the Discovery of
the John Kelly Tablet as well as photos of this interesting artifact.
It is named after the Archaeologist from Cahokia that was in charge of
the Excavation. It was actually unearthed by Elizabeth Kane, who drew
the soil profile images.
I have colorized the soil profile images using the Munsell scale
according to color references.
This artifact was found about halfway between Monks Mound Fox hill
Mound. It is made of sandstone.
One side is engraved with a crosshatching patter (x) shaped lines
interconnecting around the edges with an alternate pattern of
triangles. It is a rare example of aboriginal engraving.
The only other example I know of is from Blombous Cave, South Africa
and it was dated with thermoluminescence to 60.000BC
One of the most interesting features of this stone is its geometric
and mathematical properties. Ross Hamilton identified similar icons in
his book "The Mystery of the Serpent Mound" on page 47. Particularly
striking to compare with Figure 31.
