The following is the original first stanza, which Keats removed from the beginning of the poem before publication:
Though you should build a bark of
dead men’s bones,
And rear a phantom
gibbet for a mast,
Stitch creeds together for a sail, with groans
To fill it out, bloodstained and aghast;
Although your rudder be a
Dragon’s tail,
Long sever’d, yet still hard with agony,
Your cordage large uprootings from the skull
Of bald
Medusa: certes you would fail
To find the
Melancholy, whether she
Dreameth in any isle of
Lethe dull.
