In the tragic drama, however, historical subjects appear to necessitate a different treatment from that which most conduces to the interest of romantic narrative. There is a dignity in historical characters which scarcely permits them to be transferred to the stage without playing before the audience the important parts which they played in life. When they enter on the scene they excite a predominating interest, and we should not willingly see them deposed into secondary agencies in the conduct of the story. They ought not to be introduced at all, unless in fitting correspondence with our notions of the station they occupied and the influence they exercised in the actual world; and thus, whether they are made fated victims through their sufferings, or fateful influences through their power, still, in the drama, it is through them that the story moves: them the incidents affect—them the catastrophe involves—whether for their triumph or their fall. The drama not necessitating an original fable nor imaginary characters, that which it does necessitate in selecting a historical subject is, the art of so arranging and concentrating events in history as to form a single action, terminating in a single end, wrought through progressive incidents clearly linked together. It will be seen that the dramatic treatment is, in this respect, opposed to the purely historical treatment; for in genuine history there are innumerable secondary causes tending to each marked effect, which the dramatist must wholly eliminate or set aside. He must, in short, aim at generals to the exclusion of particulars.
