We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I got a laugh from the line describing the author, Tom Mueller. After describing the carnage, general mayhem and mechanical working of vicious spectacle, the line says: "
Tom Mueller’s next book, on the history of olive oil, will be published this fall."
According to the article in the magazine (thanks Dad), the original supports of the Hypogeum were wood, not stone, and could be removed, as well as the "floor" of the Colosseum. Then, water from a well at a higher elevation would be diverted into the arena. After the event, the water would be drained downhill.
Yup. Aqueduct from a lake or well in the hills outside the city, diverted to the stadium instead of public fountains to fill the holding tanks there.
Later the structure became too expensive to maintain (it was only used once or twice...) and stone floors and support columns were installed instead, with some wooden trapdoors and elevator mechanisms to pop up people, items, animals directly into the arena.
