Classic Churches & Buildings of Vienna
The city of Vienna is having fun with a popular program to redesign pedestrian crossing lights in response to "why is it always a guy up there?" In addition to these figures they are randomly using Yoda, kangaroos, aliens, Neanderthals, gorillas, gay and lesbian couples, even Bart Simpson carrying a sword and shield. I love it. It gives you a "box of chocolates" moment as you approach a street but cannot yet see the symbols..
Viewing the St. Charles Cathedral's dome frescoes up close showcases how artists using tricks to force a feel of perspective and distance. Figures at the top are more muted, darker, have less contrast, and less color intensity than those below. Figures are painted smaller with less crispness in the paint lines. All of this makes the top images appear much further away than they really are when viewed from the church floor. This makes the dome look higher and more majestic.
The reliefs in the window rings are too small to appreciate from the ground. Other churches in Europe have done similar detailing in places where only restoration/maintenance teams, culturally enlightened birds and Heaven could fully appreciate them. In a church, I suppose the last one is all that matters.
