To Shakspere's mastery of poetic expression similarly strong superlatives must be applied. For his form he perfected Marlowe's blank verse, developing it to the farthest possible limits of fluency, variety, and melody; though he retained the riming couplet for occasional use (partly for the sake of variety) and frequently made use also of prose, both for the same reason and in realistic or commonplace scenes. As regards the spirit of poetry, it scarcely need be said that nowhere else in literature is there a like storehouse of the most delightful and the greatest ideas phrased with the utmost power of condensed expression and figurative beauty. In dramatic structure his greatness is on the whole less conspicuous. Writing for success on the Elizabethan stage, he seldom attempted to reduce its romantic licenses to the perfection of an absolute standard. 'Romeo and Juliet, 'Hamlet,' and indeed most of his plays, contain unnecessary scenes, interesting to the Elizabethans, which Sophocles as well as Racine would have pruned away. Yet when Shakspere chooses, as in 'Othello,' to develop a play with the sternest and most rapid directness, he proves essentially the equal even of the most rigid technician. Shakspere, indeed, although as Ben Jonson said, 'he was not for an age but for all time,' was in every respect a thorough Elizabethan also, and does not escape the superficial Elizabethan faults. Chief of these, perhaps, is his fondness for 'conceits,' with which he makes his plays, especially some of the earlier ones, sparkle, brilliantly, but often inappropriately. In his prose style, again, except in the talk of commonplace persons, he never outgrew, or wished to outgrow, a large measure of Elizabethan self-conscious elegance. Scarcely a fault is his other Elizabethan habit of seldom, perhaps never, inventing the whole of his stories, but drawing the outlines of them from previous works--English chronicles, poems, or plays, Italian 'novels,' or the biographies of Plutarch. But in the majority of cases these sources provided him only with bare or even crude sketches, and perhaps nothing furnishes clearer proof of his genius than the way in which he has seen the human significance in stories baldly and wretchedly told, where the figures are merely wooden types, and by the power of imagination has transformed them into the greatest literary masterpieces, profound revelations of the underlying forces of life. Shakspere, like every other great man, has been the object of much unintelligent, and misdirected adulation, but his greatness, so far from suffering diminution, grows more apparent with the passage of time and the increase of study.
