“Porphyria’s Lover” by Robert Browning
The rain set early in to-night,
The sullen wind was soon awake,
It tore the elm-tops down for spite,
And did its worst to vex the lake: I listened with heart fit to break.
When glided in Porphyria; straight
She shut the cold out and the storm,
And kneeled and made the cheerless grate
Blaze up, and all the cottage warm;
Which done, she rose, and from her form.
