He conceived his heroes first of all as men capable of great passions, consumed by their desires, abandoned to the pursuit of their lusts, whether they led to glory, butchery, loss of kingdom, or eternal damnation. This intensity of emotion gives them an elevation and a heroic interest that outlasts contemptibility or pathos. Nor are they without representational value. They linger in the mind as men, absurd, exaggerated, monstrous at times, but appealingly human in moments when their passion rings true, and impressively typical of the eternal struggle of passion and desire against the fixed limits of human attainment. It is in the realization of their emotions that the plays secure their great impressiveness. Tragedy has become not the presentation of history, myth, or events of any sort, but the presentation of the passionate struggle and pitiful defeat of an extraordinary human being. Genuine human passion and a vital conception of life's tragedy found expression in verse, sometimes inspired, sometimes absurd, but always spontaneous and unfaltering. Blank verse, borrowed from Italy and adopted in English Senecan plays, now became a new instrument, and its preëminent adaptability for tragic poetry henceforth long remained unquestioned. If it has had many greater masters since, it had none comparable before, and, in spite of stiffness, monotony, and great unevenness, it rises now and again to remarkable technical excellence. It is _sui generis_, without known models, though it gathers to itself many of the prevailing characteristics of Renaissance poetry. It has plenty of Senecan hyperbole, but curiously little of Senecan antithesis or aphorism; it abounds in rant and bombast; it is over-adorned with classical allusion; it delights in ornament and sonority; and in the main it is declamatory and lyrical rather than dramatically suited to character and situation. Again, it is mannered and often monotonous, especially in "Tamburlaine," where the repetition of names and the recurrence of polysyllabic words at the ends of lines give the familiar swing:-- "To ride in triumph through Persepolis".... "Soft ye, my lords, and sweet Zenocrate".... "Then shall my native city, Samarcanda." Yet the lover of romantic poetry will find delight in the very impetuosity of the rant, the thunder of the declamation, the roll of the proper names, the color and pageantry of the descriptions, the occasional loveliness of the luxurious classicism, and yet more in the splendid surges of the verse to reveal the turmoil and anguish of passionate death. From the first moment Marlowe was an undoubted poet; and to his tremendous facility of words and rhythm he was adding, as "Edward II" reveals, a moderation of ornament, an evenness of power, and a dramatic consistency, while still retaining the potentiality of dazzling dramatic flash. He brought not only blank verse but poetry to the English drama, and the greatness of its style dates from his achievement.
