ESPECIALLY SO, ONCE YOU ARE OUT IN THE COUNTRYSIDE of New Mexico, religious (Spainish Catholic with a SW indigenous overlay) edifices /iconography is everywhere apparent. It seems that the Spainish missionaries spread the word with a high degree of efficiency.
The diorama pictured in the triptych, which I have presented larger in order to see the details, depicts heaven, purgatory (people milling about killing time), and hell. Hell is at the very bottom beneath a sheet of glass. Those residents ain't going no where, unlike those in purgatory who are below a cloud which they will pass through into heaven when they have served their time.
