"Philosophy will clip an Angel's wings,
Conquer all mysteries by rule and line,
Empty the haunted air, and gnomed mine-
Unweave a rainbow, as it erewhile made
The tender-person'd Lamia melt into a shade."
This is nonsense, I believe. Perhaps this is because I personally enjoy knowing things, while others think that it is unpoetic to believe that rainbows are a product of light passing through airborne water particles, rather than fairies. It's pretty either way, isn't it?
Anyway, the poem itself is a bit of a challenging read. It requires some knowledge of Greek mythology to understand. Also, Keats is definately a classicist, so, be warned. There's high vocabulary in there.
