Ballade de la Jolie Marion in White Stains by Aleister Crowley.

“Remembrance of love’s long delights
Is to remember sighs and tears,
Yet I will think upon the nights
I whispered into passionate ears
The fond desires, the sweet faint fears.
My lover’s limbs of lissome white
Gleamed in the darkness and strange light,
The wondrous orbs voluptuously
Bent on me all unearthly bright:
But we must part, and love must die.” [via]
