"March hare" -- an emblem of creative resurgence, of creative madness, if you like.  
I draw the list's attention to a compelling reading in this regard:
The abyss above:
philosophy and poetic madness in Plato, Hölderlin, and Nietzsche
Silke-Maria Weineck
State University of New York Press, 2002
"In The Abyss Above, Silke-Maria Weineck offers the first sustained discussion of the relationship between poetic madness and philosophy. Focusing on the mad poet as a key figure in what Plato called "the ancient quarrel between philosophy and poetry, " Weineck explores key texts from antiquity to modernity in order to understand why we have come to associate art with irrationality. She shows that the philosophy of madness concedes to the mad a privilege that continues to haunt the Western dream of reason, and that the theory of creative madness always strains the discourse on authenticity, pitching the controlled, repeatable, but restrained labor of philosophy against the spontaneous production of poetic texts said to be, by definition, unique."
It's fascinating to read the introductory chapter titled "Future Perfect".

I sometimes wonder if Eliot's title "Inventions of the March Hare" had something to do with the Easter Bunny.
