The magnificent Vatican Museum spiral ramp was designed by Giuseppe Momo in 1932. The ramp consists of two intertwined spirals, one bringing visitors up and the other leading down, twisting together in a double helix formation. Two decades later (1953 to be exact), Watson and Crick discovered the double helical structure of the DNA strand and the double helix came to represent life itself.
Looking down from the top of the stairs was one of those “Aha! Here you are!” moments for me. It was also when I realized I had to get a wide angle lens.
