The Reaper in The Gate of the Sanctuary from The Temple of the Holy Ghost (Collected Works, Vol I) by Aleister Crowley.

“I watched, a leopard, stealthy in the corn,
As if a tigress held herself above;
My body quivered, eager to be torn,
Stung by the snake of some convulsive love!
The leopard changed his spots; for in me leapt
The mate, the tiger. Murderous I sprang
Across the mellow earth: my senses swept,
One torrent flame, one soul-dissolving pang.
How queenly bent her body to the grip!
How lithe it slips, her bosom to my own!
The throat leans back, to tantalise the lip:—
The sudden shame of her is overthrown!” [via]
