"With all due respect to Joe, I am certain it wasn't intended to be a rattlesnake. I think if it were a rattlesnake, it would be coiled up on top of his head. Once again, I'm only guessing."
I don't think I said that it was a rattlesnake. If I did, Wiz will be along in a minute to correct me.

I said:
"If the Maya were carving a snake, it's skin would be immediately recognizable as a specific member of the rattlesnake family."
Archaeologist, Jose Diaz Bolio has written that the Maya quite literally derived their knowledge of the world "from the mouth of a rattlesnake".
The rattlesnake which they held in such awe, was Crotalus durissus durissus. The Mayan name for this particular species was, Ahau Can which means, "Great, lordly serpent". The pattern on it's skin was so distinctive that it is the basis for a good deal of Mayan art, architecture, science of geometry and a possible reason behind the design of their pyramids. Peter would appreciate the way the four cardinal points are depicted in the pattern of their skin, and how this reverence for the designs on the "Great, lordly serpent" may have actually been the inspiration for "all American Indian architecture."
Having said all of that, it is also possible that it is not a snake's head at all.
Bill,
After reading your post, I think you meant to say you agree with Laz, not me.

Respectfully,
Joe
