John Keats wrote a sonnet “On sitting down to read King Lear once again”: having burned his way through the play, he would feel somehow purified and regenerated.
"On Sitting Down to Read King Lear Once Again" by John Keats (1818):
Golden-tongued Romance, with serene Lute!
Fair plumed Syren, Queen of far-away!
Leave melodizing on this wintry day
Shut up thine olden Pages, and be mute.
Adieu! for, once again, the fierce dispute,
Betwixt Damnation and impassion'd clay
Must I burn through; once more humbly assay
The bitter-sweet of this Shaksperean fruit.
Chief Poet! and ye Clouds of Albion,
Begetters of our deep eternal theme!
When through the old oak forest I am gone,
Let me not wander in a barren dream:
But, when I am consumed in the fire,
Give me new Phoenix Wings to fly at my desire.
