Did you know that Pompeii is an excellent example of temporal and spatial palimpsests? Fancy pantsy.

What on earth is a palimpsest?  Something having usually diverse layers or aspects apparent beneath the surface.  So, Pompeii has both temporal (time stamped/era/period) and spatial (same location and related) palimpsests, since the city is essentially a time capsule.  Alright, you may now carry on with your day.
