The World's Desire by H. Rider Haggard

Rei departed, wondering and heavy at heart, and Meriamun the Queen passed into her bed-chamber, and there she bade the eunuchs suffer none to enter, made fast the doors, and threw herself down upon the bed, hiding her face in its woven cushions. Thus she lay for many hours as one dead-till the darkness of the evening gathered in the chamber. But though she moved not, yet in her heart there burned a fire, now white with heat as the breath of her passion fanned it, and now waning black and dull as the tears fell from her eyes. For now she knew all-that the long foreboding, sometimes dreaded, sometimes desired, and again, like a dream, half forgotten, was indeed being fulfilled. She knew of the devouring love that must eat her life away, knew that even in the grave she should find no rest.

And her foe was no longer a face beheld in a vision, but a living woman, the fairest and most favoured, Helen of Troy, Argive Helen, the False Hathor, the torch that fired great cities, the centre of all desire, whose life was the daily doom of men.
