The Nameless Quest in The Gate of the Sanctuary from The Temple of the Holy Ghost (Collected Works, Vol I) by Aleister Crowley.
“‘You know I will not strike, Sir pure and brave!
Fight me your best—or I shall find a whip!’
That stung me, even me. He wronged me, so:
Therefore some shame and hate informed the blow;
Some coward’s courage pointed me the steel;
Some strength of Hell: we lunge, and leap, and wheel;
Hard breath and laboured hands—the flashes grow
Swifter and cruel—this court hath no appeal!” [via]
