I like what you said about Roman culture being a melting pot of many of the cultures that came before it. You’re so right in that this compilation would make what we understand to be ‘Roman’ to stick around for so many years. Roman architecture was heavily influenced by the Greek and Etruscan architecture. Also, the fact that so much of their architecture is still standing, and is so wide spread, makes their influence very long lasting. I hadn’t considered that as a potential reason for their influence to have been so great.
