I've been thinking about this since I saw that you posted it. It's a cross to me between whether I would try to describe what I imagine when I'm there, or describe the ruins as they exist. Half of visiting an archaelogical site to me is trying to picture it as it was when people actually lived there, so sites like Delphi are already an exercise in imagination. (My description that I wrote was far too long and is not allowing me to post. I'm going to give it its own entry today.)
