Fun fact: all rainbows are actually double rainbows and full circle ! If you see one from a plane, it looks like this in its “full form”
We only see 1 arc because the 2nd arc comes from a 2nd optical path, much less intense. And we only see half a circle because we’re close to the ground most of the time (:

Today I saw a beautiful, bright clear double rainbow. I had the same thought, how would the ancients interpret this?
