I am so glad I asked!
I don’t know if you know that 1/2 my undergraduate double major was Classical Archaeology. I saw a lot of Greek sculpture, and I did note that the male genitalia seemed proportionately small. No text or professor ever mentioned the connection to rising above the animal nature, but it was the 70s, so genitals were not a subject of polite conversation. (Are they now?) However, we did joke in class that the depictions of breasts on pottery looked as though the women had lemons tucked under their arms.
I am aware of the influence of Greek culture on the architecture of the new republic (aka Greek revival), which saw itself as the heir to Greek democracy. The 1921 McIntire Amphitheatre was was the 7th in the US.
But, here’s a tidbit for you I did learn in college: how to tell a Greek original from a Roman copy. Look at the toes. Greek sculptures almost always have the second toe longer than the big toe, but not the Romans. They liked their toes in a nice arc, even when they were copying a Greek masterpiece.
