This is tangential to the discussion, but I recently heard Barbara
MacLeod giving a reading of the monument and she began by identifying
a "pulque god" glyph, but I didn't see the exact glyph she was
referring to. I'm assuming it's in the A2 position at the upper-left
of the monument, but want to be sure. Are there examples of this
glyph on other monuments? Is this interpretation solid? What is
purpose or function of the pulque god within the larger narrative?
