Much of Marlowe's strength, again, lies in his powerful and beautiful use of blank verse. First among the dramatists of the popular stage he discarded rime, and taking and vitalizing the stiff pentameter line of 'Gorboduc,' gave it an immediate and lasting vogue for tragedy and high comedy. Marlowe, virtually a beginner, could not be expected to carry blank verse to that perfection which his success made possible for Shakspere; he did not altogether escape monotony and commonplaceness; but he gained a high degree of flexibility and beauty by avoiding a regularly end-stopped arrangement, by taking pains to secure variety of pause and accent, and by giving his language poetic condensation and suggestiveness. His workmanship thoroughly justifies the characterization 'Marlowe's mighty line,' which Ben Jonson in his tribute to Shakspere bestowed on it long after Marlowe's death. The greatest significance of 'Tamburlaine,' lastly, lies in the fact that it definitely established tragedy as a distinct form on the English popular stage, and invested it with proper dignity. These are Marlowe's great achievements both in 'Tamburlaine' and in his later more restrained plays. His limitations must also be suggested. Like other Elizabethans he did not fully understand the distinction between drama and other literary forms; 'Tamburlaine' is not so much a regularly constructed tragedy, with a struggle between nearly equal persons and forces, artistically complicated and resolved, as an epic poem, a succession of adventures in war (and love). Again, in spite of the prolog in 'Tamburlaine,' Marlowe, in almost all his plays, and following the Elizabethan custom, does attempt scenes of humor, but he attains only to the coarse and brutal horse-play at which the English audiences had laughed for centuries in the Mystery plays and the Interludes. Elizabethan also (and before that medieval) is the lack of historical perspective which gives to Mongol shepherds the manners and speech of Greek classical antiquity as Marlowe had learned to know it at the university. More serious is the lack of mature skill in characterization. Tamburlaine the man is an exaggerated type; most of the men about him are his faint shadows, and those who are intended to be comic are preposterous. The women, though they have some differentiating touches, are certainly not more dramatically and vitally imagined. In his later plays Marlowe makes gains in this respect, but he never arrives at full easy mastery and trenchantly convincing lifelikeness either in characterization, in presentation of action, or in fine poetic finish. It has often been remarked that at the age when Marlowe died Shakspere had produced not one of the great plays on which his reputation rests; but Shakspere's genius came to maturity more surely, as well as more slowly, and there is no basis for the inference sometimes drawn that if Marlowe had lived he would ever have equalled or even
