With my beloved I lingered late one night.
At last the hour when I must leave her came:
But, as I turned, a fear I could not name
Possessed me that the long sweet evening might
Prelude some sudden storm, whereby delight
Should perish. What if death, ere dawn, should claim
One of us? What, though living, not the same
Each should appear to each in morning-light?
Changed did I find her, truly, the next day:
Ne'er could I see her as of old again.
That strange mood seemed to draw a cloud away,
And let her beauty pour through every vein
Sunlight and life, part of me. Thus the lover
With each new morn a new world may discover.
