Why Is The Sky Blue?

Gaia disdains that her airy robe
should be sun-white by day and black by night--
unsubtle cloth, to wrap this gorgeous globe.

So she bends light, wrapping gold and red
(and orange-madder, purple, conch-lip pink)
around her hem, like strands of colored thread.

I on my porch enjoy the sunset hues,
knowing that westwards, folk looking up at noon
will see the heart of Gaia’s robe, sky-blue.
