Huh?

Not the OP, but I have heard that Rome is defined by the seven hills, so I thought the Aurelian Wall definition was excluding a hill or something. The Wikipedia article says the walls cover all seven hills and the Campus Martius: https://en.wikipedia.org/wiki/Aurelian_Walls

Are you saying you'd include even more in "the size of Rome (the city)"? If so, what?

There were some people living outside that perimeter, but I just included the Seven Hills and the Campus Martius because it was a typical border for the city and was densely packed with maybe a million people. Teotihuacan possibly had up to 200,000 people, so a bit more breathing room.
