Set on a wall of the important Structure 22, this witz (mountain) mask marks the whole structure as being a symbolic mountain. In the ancient Maya cosmovision, pyramids were thought of as mountains, while the temples crowning them were conceived as caves. A strong argument can be made that, in the Maya mindset, these associations were not allegorical: their structures were thought of as becoming actual mountains and caves by virtue of the all-important act of naming them as such.
