After taking a three-week tour to Europe recently, the perceptions brought home are multi-layered, and intricate. But most of all, what I think about is scale. I've been to big cities before, with big buildings, big spaces, and yes, sprawl as far as the eye can see, studded dense with urban constructs. There is something however that makes me blink and do a double take in Europe, and that's about the size of some the architectural specimens visible there. Even on 21st-century terms, those folks who designed and hewed were thinking big. No, strike that… I meant colossal. It is sublime to not only stand amongst these wonders, but to think of being part of the human family they have sung to for hundreds and in some cases, even a couple thousand years.
