When he left the life of a dissolute young noble for that of tragic authorship, he seized upon such histories and fables as would give the freest course to a harsh, narrow, gloomy, vindictive, and declamatory nature; and his dramas reproduce the terrible fatalistic traditions of the Greeks, the stories of Oedipus, Myrrha, Alcestis, Clytemnestra, Orestes, and such passages of Roman history as those relating to the Brutuses and to Virginia. In modern history he has taken such characters and events as those of Philip II., Mary Stuart, Don Garzia, and the Conspiracy of the Pazzi. Two of his tragedies are from the Bible, the Abel and the Saul; one, the Rosmunda, from Longobardic history. And these themes, varying so vastly as to the times, races, and religions with which they originated, are all treated in the same spirit--the spirit Alfieri believed Greek. Their interest comes from the situation and the action; of character, as we have it in the romantic drama, and supremely in Shakespeare, there is scarcely anything; and the language is shorn of all metaphor and picturesque expression. Of course their form is wholly unlike that of the romantic drama; Alfieri holds fast by the famous unities as the chief and saving grace of tragedy. All his actions take place within twenty-four hours; there is no change of scene, and so far as he can master that most obstinate unity, the unity of action, each piece is furnished with a tangible beginning, middle, and ending. The wide stretches of time which the old Spanish and English and all modern dramas cover, and their frequent transitions from place to place, were impossible and abhorrent to him.
