"One opal cloudlet in an oval form
Reflects the rainbow of a thunderstorm
Which in a distant valley has been staged--
For we are most artistically caged."
Well, I first read this in the morning; in late afternoon the same day, I went out for a walk along the country road near my house. It had sprinkled lightly earlier in the day, but was still nice. On the way home, I looked toward the west, and I saw in the distant sky this oval batch of cloud with an iridescent sort-of rainbow around the top edge of it. It was very beautiful, and I was very struck, encountering this image that I had read earlier in this, the "real world". Was it one of those cosmic instances of what Oscar Wilde called "Life imitating art"? Or was it my imagination drawing connections between two different instances of perception? In any event, it was very striking and indelible to me.
