A dozen cirrus medallions stretched out across the entire length of a blue sky, like something I don’t think I’ve ever seen – not a line of cirrus or a field, but twelve separate and distinct circular or oval shield-like islands in a row. One was like an x-ray of spine and rib cage, another like a fan you might cool yourself with in a church, and another a big heart-shaped paulownia leaf. One was a ray swimming fast, trailing streaks of bubbles in the water; another was a coat of arms in which you could divine your own emblems; and another was a broad chiseled arrowhead. They all came under the technical cloud designation cirrographicus.
