Why however does not the ruthless Macbeth live down the murder of the king as he does in the history? I believe that we must here go still further back than to the Chronicle, even to the creator of the tragedy himself. There is a certain important crisis in Shakespeare's life, where according to the biography by George Brandes "cheerfulness, the very joy of life, was extinguished in his soul. Heavy clouds gathered over his horizon, we now do not know just what their source. Gnawing griefs and disappointments gathered within him. We see his melancholy grow and extend itself; we can observe the changing effects of this melancholy without clearly recognizing its cause. Only we feel this, that the scene of action which he sees with the inner eye of the soul has now become as black as the external scene of which he makes use. A veil of phantasy has sunk down over both. He writes no more comedies but puts a succession of dark tragedies upon the stage, which lately reëchoed to the laughter of his Rosalinds and Beatrices." This crisis came in the year 1601, when the earl of Essex and Lord Southampton, Shakespeare's special patron, were condemned to death because of treason against the life of the king. According to Brandes the depression over their fate must have been one of the original causes for the poet's beginning melancholy. Perhaps the death of Shakespeare's father, which followed some months later, made a more lasting impression with all the memories which it recalled. The dramas which the poet published about that time, Julius Cæsar, Hamlet and Macbeth, have a common theme, they all revolve about a father murder. In "Julius Cæsar," Brutus murders his fatherly friend, his mother's beloved ("And thou too, my son Brutus?"). Hamlet comes to shipwreck in his undertaking to avenge upon his uncle the father's murder, because the uncle, as Freud explains in his "Interpretation of Dreams," had at bottom done nothing else than Hamlet had wished in his childhood but had not had the self confidence to carry out. And Macbeth in the last analysis is ruined by the king and father murder, the results of which he can never overcome. We may consider this theme of the father murder, always presented in some new form, in the light of its direct precipitating causes, the actual death of Shakespeare's father and Southampton's treason against the ruling power of the state. It is not difficult to accept that at that time the infantile death wishes against his father were newly awakened in our poet himself and were then projected externally in a series of powerful dramas.
