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.
