Onward through the Yucatánic fog
Chac Mool was a figment of fancy belonging to Augustus Le Plongeon, 3D photographer and father of Plongeonetics. He dug up a statue at Chichen Itza in eighteen something and named it such after the King of Mu. Plongeonism has it that Mayans visited Atlantis on their way to Egypt where they erected slightly more pointy pyramids. It helped that they had electricity.
There aren't too many Plongeonistas left today to perpetuate such myths, mainly because Augustus urged all of his followers to invest in clay coins of his realm, such as is shown here. He called them Chac-moolians and minted gobs and gobs of them. The only use Yucatanian market vendors got out of them was throwing them back at the schlonkers who tried to pass them off. Which is why so many of them are recovered today by just scratching the surface ground in old market places. No one ever bothered to pick them up.
