Of Shakespeare's other plays the several groups exercised a more direct influence upon the general progress of our dramatic literature. His Roman tragedies, though following their authorities with much the same fidelity as that of the English _histories_, even more effectively taught the great lesson of free dramatic treatment of historic themes, and thus pre-eminently became the perennial models of the modern historic drama. His tragedies on other subjects, which necessarily admitted of a more absolute freedom of treatment, established themselves as the examples for all time of the highest kind of tragedy. Where else is exhibited with the same fulness the struggle between will and obstacle, character and circumstance? Where is mirrored with equal power and variety the working of those passions in the mastery of which over man lies his doom? Here, above all, Shakespeare as compared with his predecessors, as well as with his successors, "_is_ that nature which they paint and draw." He threw open to modern tragedy a range of hitherto unknown breadth and depth and height, and emancipated the national drama in its noblest forms from limits to which it could never again restrict itself without a consciousness of having renounced its enfranchisement. Happily for the variety of his creative genius on the English stage, no divorce had been proclaimed between the serious and the comic, and no division of species had been established such as he himself ridicules as pedantic when it professes to be exhaustive. The comedies of Shakespeare accordingly refuse to be tabulated in deference to any method of classification deserving to be called precise; and several of them are comedies only according to a purely technical use of the term. In those in which the instinct of reader or spectator recognizes the comic interest to be supreme, it is still of its nature incidental to the progress of the action; for the criticism seems just, as well as in agreement with what we can conclude as to Shakespeare's process of construction, that among all his comedies not more than a single one[185] is in both design and effect a comedy of character proper. Thus in this direction, while the unparalleled wealth of his invention renewed or created a whole gallery of types, he left much to be done by his successors; while the truest secrets of his comic art, which interweaves fancy with observation, draws wisdom from the lips of fools, and imbues with character what all other hands would have left shadowy, monstrous or trivial, are among the things inimitable belonging to the individuality of his poetic genius. His style and its influence.
