In rhythm Keats adheres in _Endymion_ to the method he had adopted in _Sleep and Poetry_, deliberately keeping the sentence independent of the metre, putting full pauses anywhere in his lines rather than at the end, and avoiding any regular beat upon the rhyme. Leigh Hunt thought Keats had carried this method too far, even to the negation of metre. Some later critics have supposed the rhythm of _Endymion_ to have been influenced by the _Pharonnida_ of Chamberlayne: a fourth-rate poet remarkable chiefly for two things, for the inextricable trailing involution of his sentences, exceeding that of the very worst prose of his time, and for a perverse persistency in ending his heroic lines with the lightest syllables--prepositions, adverbs and conjunctions--on which neither pause nor emphasis is possible[36]. But Keats, even where his verse runs most diffusely, rarely fails in delicacy of musical and metrical ear, or in variety and elasticity of sentence structure. There is nothing in his treatment of the measure for which precedent may not be found in the work of almost every poet who employed it during the half-century that followed its brilliant revival for the purposes of narrative poetry by Marlowe. At most, he can only be said to make a rule of that which with the older poets was rather an exception; and to seek affinities for him among the tedious by-ways of provincial seventeenth-century verse seems quite superfluous. As the best criticism on Keats's _Endymion_ is in his own preface, so its best defence is in a letter he wrote six months after it was printed. "It is as good," he says, "as I had power to make it by myself." Hunt had warned him against the risks of a long poem, and Shelley against those of hasty publication. From much in his performance that was exuberant and crude the classical training and now ripening taste of Shelley might doubtless have saved him, had he been willing to listen. But he was determined that his poetry should at all times be the true spontaneous expression of his mind. "Had I been nervous," he goes on, "about its being a perfect piece, and with that view asked advice, and trembled over every page, it would not have been written; for it is not in my nature to fumble. I will write independently. I have written independently _without judgment_. I may write independently and _with judgment_ hereafter. The genius of poetry must work out its own salvation in a man. It cannot be matured by law and precept, but by sensation and watchfulness in itself." How well Keats was able to turn the fruits of experience to the benefit of his art, how swift the genius of poetry in him was to work out, as he says, its own salvation, we shall see when we come to consider his next labours.
