It is, however, indispensable to remark, that in each of these characters there are two distinct realities. The one tries, by a display of too much energy, to overstep the limits of the natural; the other brings the subject back to its true proportions by idealizing it. The first is the result of the poet's observations of men and their customs, or of his study of history; the other, by the impossibility which he knows to exist in him of departing from the rules of art by pushing reality to the point of making of it a positive suffering. In the first case his heroes are like one another by their analogy in the use and abuse of strength; in the other they are like Byron, because he has almost instilled a portion of his own life into them, in order to idealize them. Conrad is the real pirate of the AEgean Sea: independent, haughty, terrible in battle, full of energy and daring such as becomes the chief of corsairs, and such as Byron's study of the country where the action lies pointed out to him that such a man should be placed. But the poet describes himself when he makes Conrad, at the risk of his own life, save women from a harem, or shudder at the sight of a drop of blood on the brow of a lovely maiden. The spot on Gulnare's forehead, while causing him to suspect some crime, banishes all her charms in his eyes, and inspires him with the greater horror from the fact that the love which she had sworn him probably inspired her with the foul act, to save his life and restore him to liberty. He accuses himself with having been the involuntary cause of it, and feels that his gratitude will be a torture; his former love for Gulnare an impossibility. We find Byron's own nature again in the ascetic rule of life to which Conrad has subjected himself, and in his passionate and ideal tenderness for Medora, whose love, in his eyes, surpasses all the happiness of this world, and whose death plunges him into irretrievable despair. In the "Siege of Corinth," Alp is the real type of the historical Venetian renegade, who is incapable of forgiveness, and who makes use of all his energies to gratify his revenge. But he represents Byron when he speaks of the impressions which he felt under the starry canopy of heaven the night before the battle, when his imagination, taking him back to the happy, innocent days of his childhood, he contrasts them with the present, which for him is one of remorse, and when there glimmer still in his soul faint lights of humanity which make him turn away from the horrible sight of dogs devouring the dead bodies of men.
