…and the “o”s in the poem graphically convey what the moon does from the time it first rises to the time when it is overhead: it appears to grow smaller.
We were driving home as dusk turned into night, and Carol looked into the rear view mirror and said, “Look at the moon! It’s huge!” It had just appeared over the horizon. She wondered aloud, Why did the moon look so huge? Why did it get smaller?
I explained the optical illusion that makes the moon look big on the horizon. “If you hold out a piece of cardboard at arm’s length and put two marks on it showing how wide the moon is — and then hold that same piece of cardboard out at arm’s length when the moon is overhead and looks so small — you can see it’s exactly the same size all the time, even though it looks so much bigger near the horizon.” I actually did just that many years ago; even though I knew, intellectually, what was going to happen, it was astonishing.
Carol said that explanation takes all the magic out of it. But I disagree. How amazing that we see the world in that way! How amazing that there is more than one way to see the world!
When we got home, we walked out into the cemetery and watched the moon rise further into the sky, moving slowly up between two dark clumps of eucalyptus, just touching the point of a smaller Douglas-fir tree. You could see the distance between the Douglas-fir and the moon slowly grow greater. You could see Mare Ibrium and Oceanus Procellarum and Mare Fecuditatis and Mare Nectaris; you could also see the Rabbit in the Moon, grinding with its mortar and pestle; you could also see the Man in the Moon, with his lopsided grin. You could see the night grow darker and the moon grow brighter. Everything changed in a quarter of an hour. We stayed outside watching until it grew too chilly.
