After the first weeks of autumn gloom spent in solitary lodgings in the dingiest part of London, Keats expresses, in a rimed epistle to Felton Mathew, the fear lest his present studies and surroundings should stifle the poetic faculty in him altogether. About the same time he takes pains to get into touch again with Cowden Clarke, who had by this time left Enfield and was living with a brother-in-law in Clerkenwell. In a letter unluckily not dated, but certainly belonging to these first autumn weeks in London, Keats writes to Clarke:--'Although the Borough is a beastly place in dirt, turnings, and windings, yet No 8, Dean Street, is not difficult to find; and if you would run the gauntlet over London Bridge, take the first turning to the right, and, moreover, knock at my door, which is nearly opposite a meeting, you would do me a charity, which, as St Paul saith, is the father of all the virtues. At all events, let me hear from you soon: I say, at all events, not excepting the gout in your fingers.' Clarke seems to have complied promptly with this petition, and before many months their renewed intercourse had momentous consequences. Keats's fear that the springs of poetry would dry up in him was not fulfilled, and he kept trying his prentice hand in various modes of verse. Some of the sonnets recorded to have belonged to the year 1815, as _Woman, when I behold thee, Happy is England_, may have been written in London at the close of that year: a number of others, showing a gradually strengthening touch, belong, we know, to the spring and early summer of the next. For his brother George to send to his _fiancee_, Miss Georgiana Wylie, on Valentine's day, Feb. 14, 1816, he wrote the pleasant set of heptasyllabics beginning 'Hadst thou lived in days of old.' In the same month was published Leigh Hunt's poem _The Story of Rimini_, and by this, working together with his rooted enthusiasm for Spenser, Keats was immediately inspired to begin an attempt at a chivalrous romance of his own, _Calidore_; which went no farther than an Induction and some hundred and fifty opening lines.
