In February 1818 Keats, Leigh Hunt, and Shelley, undertook to write a sonnet each upon the river Nile. In order of merit, the three sonnets are the reverse of what one might have been willing to forecast. I at least am clearly of opinion that Hunt's sonnet is the best (though with a weak ending), Keats's the second, and Shelley's a decidedly bad third. The leading thought in each sonnet is characteristic of its author. Keats adheres to the simple natural facts of the case, while Hunt and Shelley turn the Nile into a moral or intellectual symbol. Keats says essentially that to associate the Nile with ideas of antique desolation is but a delusion of ignorance, for this river is really rich and fresh like others. Hunt makes the Egyptian stream an emblem of history tending towards the progress of the individual and the race; while Shelley reads into the Nile a lesson of the good and the evil inhering in knowledge. "The Eve of St. Mark"--a fragment which very few of Keats's completed poems can rival in point of artist-like feeling and writing--belongs to the years 1818-9. I find nothing in print to account for his leaving it unfinished. In May 1819 Keats had an idea of inventing a new structure of sonnet-rhyme; and he sent to his brother and sister-in-law a sonnet composed accordingly, beginning-- "If by dull rhymes our English must be chained." He wrote: "I have been endeavouring to discover a better sonnet-stanza than we have. The legitimate does not suit the language well, from the pouncing rhymes. The other appears too elegiac, and the couplet at the end of it has seldom a pleasing effect. I do not pretend to have succeeded." Keats's experiment reads agreeably. It comprises five rhymes altogether; the first rhyme being repeated thrice at arbitrary intervals; and the last rhyme twice in lines twelve and fourteen.
