la belle dame sans merci

The painting is based on the poem of the same name by John Keats. The poem below -
" O WHAT can ail thee, knight-at-arms,
Alone and palely loitering?
The sedge has wither'd from the lake,
And no birds sing.

"O what can ail thee, knight-at-arms!
So haggard and so woe-begone?
The squirrel's granary is full,
And the harvest's done.

"I see a lily on thy brow
With anguish moist and fever-dew.
And on thy cheeks a fading rose
Fast withereth too."

"I met a lady in the meads,
Full beautiful—a faery's child,
Her hair was long, her foot was light,
And her eyes were wild.

"I made a garland for her head,
And bracelets too, and fragrant zone;
She look'd at me as she did love,
And made sweet moan.

"I set her on my pacing steed,
And nothing else saw all day long;
For sidelong would she bend, and sing
A faery's song.

"She found me roots of relish sweet,
And honey wild and manna-dew;
And sure in language strange she said,
'I love thee true.'

"She took me to her elfin grot,
And there she wept and sigh'd full sore;
And there I shut her wild, wild eyes
With kisses four.

"And there she lullèd me asleep,
And there I dream'd—ah! woe betide!
The latest dream I ever dream'd
On the cold hill's side.

"I saw pale kings and princes too,
Pale warriors, death-pale were they all:
They cried, 'La belle Dame sans Merci
Hath thee in thrall!'

"I saw their starved lips in the gloam
With horrid warning gapèd wide,
And I awoke and found me here
On the cold hill's side.

"And this is why I sojourn here
Alone and palely loitering,
Though the sedge is wither'd from the lake,
And no birds sing."
