Today, I attended a summer solstice event at Santa Maria del Fiore (aka the Duomo)—the observation of the transit of the sun on the meridian plane, a phrase I don’t understand any better than I did when I attended Lo Gnomone a couple of years ago! As with reading certain books, though, I hope that repetition will eventually lead to some degree of understanding.
What stood out for me this year, having seen this before, was the reaction of other people. When the sun’s rays first appeared on the pillar opposite me, the couple next to me was astonished. When the sun’s light morphed into a disc on the floor, people were craning necks and lifting phone cameras to capture the image, especially since it disappeared and reappeared as clouds moved over the sun. When the disc of light eventually covered the marble disc on the floor, the woman next to me said, “You can actually see the sun move.” When I repeated what the professor giving the presentation said, “It is we who are moving,” her eyes widened and she said, “You’re right!” It was a great moment of connection over this interesting phenomenon.
