The Two Floods, Double Rainbows, and the Cosmic Limitations of Engineering

On double rainbows in Noah

A few years ago, my daughter showed me a viral video of a stoned guy blissing out on a double rainbow in Yosemite. “It’s … it’s a double rainbow!” He moans. “Oh my G-d, oh my G-d,” he repeats over and over, “It’s so bright.  Ohhhh, it’s so beautiful!” He breaks down in full-on sobbing, crying in a seizure of ecstasy. “What does it mean?” he asks, his mind blown.

I’m not sure, dude. But one thing you missed in your rapture is a curious phenomenon: look carefully and you can see that the colors of the second rainbow invert the usual order: VIBGYOR.

As early as 1520 or so, the Jewish sage Sforno[i] noted that even by his time, the double rainbow was already a cliché.

“Scientists have already tired of trying to explain why the various colors of the second rainbow appear in the opposite order of the colors in the original rainbow.”[ii]

Nonetheless, he uses it to explain the rainbow following Noah’s flood. Since the ordinary rainbow already existed at the time of Creation, Sforno reasons, the actual rainbow displayed after the Flood must be this second rainbow, a much rarer and more startling sight (as our ecstatic friend saw in Yosemite). The reverse order of the colors are a warning:

 “When this rainbow appears it is high time to call people to order and to warn them of impending natural calamities unless they change their ways.”[iii]

Sforno’s insight made me think of another secret duality in Noah: there’s really not one but two floods in this weekly reading. I believe they’re connected. Continue reading “The Two Floods, Double Rainbows, and the Cosmic Limitations of Engineering”
