We don’t need to understand why a rainbow or fogbow is formed in order to appreciate its beauty, of course, but understanding the physics of rainbows does give us a new set of eyes. I call this the beauty of knowledge.
~Walter Lewin from For the Love of Physics
Ghaist o a gaw that few hae seen
paintit on fog lyk a fugue o thi scheme
Noah supposit thi Lord tae mean
when aa were drooned,
ither hauf o yin o His een
thon runic roond.
Rope o smoke lyk a loop on a cable,
Grisaille Cain tae thi rainbow’s Abel,
ultra-blank tae infra-sable,
auld noose o tow;
Yin that’s strang whaur Yang is faible:
faur are ye now?
~WN Herbert “The Fogbow” from Omnesia
(this is my best guess of the meaning of Herbert’s inventive English/Gaelic/Scottish)
Ghost of a rainbow bruise that few have seen
painted on fog like a fugue of this scheme
Noah supposed the Lord to mean
when all were drowned
the other half of the dark cold earth is
a mysterious rune ruined.
A rope of smoke like a loop on a cable
a gray pallid Cain to the rainbow’s Abel,
outer-white to inner-black
old noose in tow;
the cold and dark is strong where warmth and light is feeble:
where are you now?
Look at a rainbow.
While it lasts, it is or appears to be,
a great arc of many colours occupying a position out there in space….
And now, before it fades, recollect all you have ever been told about the rainbow and its causes, and ask yourself the question,
Is it really there?
You know from memory that if you walked to the place where the rainbow ends, or seems to end, it would certainly not be ‘there’. In a word, reflection will assure you that the rainbow is the outcome of the sun, the raindrops and your own vision.
~Owen Barfield writing about “The Rainbow”
We saw our first “fogbow” or “ghost rainbow” early yesterday on our morning walk. It happened as we were heading east toward the sun, with the fog thickening, filling in behind us. We had just turned around to check the road to be sure no cars were coming before we crossed to the other side and there was this spectral image of foggy columns curving upward over the road to barely touch one another at the top. As we moved away from it, it vanished, as they say, “into thin air.”
This is an unusual phenomenon where the light and moisture in the air needs to be just right – reading about the physics of the fogbow helps to explain it and to render it even more beautiful. But the knowledge of how it happens isn’t nearly as impactful as the fact it was there at all for us to witness. Without our vision, it wasn’t really “there.”
The “bruised” rainbow color in the sky is God’s Old Testament promise to Noah to never destroy the world by flood again, establishing an everlasting covenant with His people while giving us the capacity to witness His promise. Perhaps the fogbow is ghostly reminder of those who have perished, whose blood, like Abel’s, cried out to God from the earth.
But where are we now? Do we seek to understand, believing the promises God made to us? Or do we walk right past God and His miraculous physics of creation, oblivious to what would not even exist without our ability to see it?
Somewhere, over the fogbow, way up high…
