As when desire, long darkling, dawns, and first
The mother looks upon the newborn child,
Even so my Lady stood at gaze and smiled
When her soul knew at length the Love it nurs'd.
Born with her life, creature of poignant thirst
And exquisite hunger, at her heart Love lay
Quickening in darkness, till a voice that day
Cried on him, and the bonds of birth were burst.
Now, shadowed by his wings, our faces yearn
Together, as his full-grown feet now range
The grove, and his warm hands our couch prepare:
Till to his song our bodiless souls in turn
Be born his children, when Death's nuptial change
Leaves us for light the halo of his hair.

Dante Gabriel Rossetti
