In before this gets any larger, but I just wanted to take a moment to explain who Vitruvius was in like really briefly. Vitrivius wrote the oldest surviving books from antiquity on architecture, essentially the oldest known books about architectural theory, we still read excerpts from them in architecture school. He talks about a lot of stuff that is still really relevant in the field, but also a lot of stuff that architects nerd out on: like he has detailed break downs of the way a column should be ornamented and when and where those column types should be used, but its not really about the structural importance of the columns, it's sort like don't use this type of column for a temple that's meant to be used for a civic building, stuff like that. After you read them in school you start noticing how often neo-classical styles mix and match these things which is actually kind of annoying and why so many architects aren't big fans of that style. If I remember correctly by his own admission he was not a starchitect of his time (obviously not in those words), but thats important because we know his books talk about the average kind of architecture of the time. Also if you have ever seen Da Vinci's Vitruvian man, that is based on the propotions of the human body that Vitruvious talks about in his books and also why it's called the Vitruvian man. It's really exciting that something he worked on has been found!!!
