There's an unusual, but mellifluous word pallia I once used in a poem. It is the equivalent of cerebral cortex. It also means some kind of robe worn by Roman officials/dignitaries. In the poem, I saw the cerebral cortex of an oak grove in the exposed, bare winter crowns of the trees, a symbol for the collective minds of the People in disagreement with Heavenly allowance of atrocity. The specific line was:

"The pallia of bare oak crowns locked with the Sky."

What's interesting to me in this thread is to learn that the cortex itself can mean "bark," which I find to be a coincidental connection between the word I chose, pallia, and the bark. But Jung would say the word choice wasn't just coincidental.
