Pompeii's Sewers, Latrines, Cesspits......

Archeologists spend three days in Rome discussing Pompeii's sewer discoveries! Fishbones, goose egg shells, dates!

Then it has been recently discovered that Pompeii had upstairs toilets, just like modern homes do!

There are way too many ads on this next link, but there is a brief history of toilets that are worth a click through, some types of which I have shown you in the past.

I guess our old toilets will resurface someday in the dumps of the world and be a learning experience and a curiosity too, the way Pompeii's findings are for us today.  But our septic tanks will be pumped and cleaned before we either fill them with rocks or repurpose them prior to sewer hook-up. The future will be deprived of what I suspect would have been found (besides what you would expect, molded and petrified)—some plastic figurines that today's children sent on a watery voyage beneath the pee.
