I blogged some time ago about a double rainbow. There were quite a few of those where we were last week. But a friend helpfully pointed out that we're not actually seeing two rainbows. We're seeing one rainbow and its reflection. Sure enough, if you look at the pic you'll see that the colours go in opposite directions. One rainbow is a mirror image of the other. While I was taken with the idea of a double rainbow symbolising double the hope and double the blessing, I quite like the idea of the beauty being reflected too. Take your pick - science or imagination? Both have much to offer.
