For she lies, laughing low with love; she lies
And turns his kisses on her lips to sighs,
To sighing sound of lips unsatisfied,
And the sweet tears are tender with her eyes.

Ah, not as they, but as the souls that were
Slain in the old time, having found her fair;
Who, sleeping with her lips upon their eyes,
Heard sudden serpents hiss across her hair.

Their blood runs round the roots of time like rain:
She casts them forth and gathers them again;
With nerve and bone she weaves and multiplies
Exceeding pleasure out of extreme pain.

Algernon Charles Swinburne, from 'Laus Veneris'
