6Macbeth: The Tragedy of Macbeth by William Shakespeare. Macbeth; full title The Tragedy of Macbeth, is a tragedy by William Shakespeare; it is thought to have been first performed in 1606. The play opens amidst thunder and lightning, and the Three Witches decide that their next meeting shall be with Macbeth. In the following scene, a wounded sergeant reports to King Duncan of Scotland that his generals-Macbeth, who is the Thane of Glamis, and Banquo-have just defeated the allied forces of Norway and Ireland, who were led by the traitorous Macdonwald, the Thane of Cawdor. Macbeth, the King's kinsman, is praised for his bravery and fighting prowess. In the following scene, Macbeth and Banquo discuss the weather and their victory. As they wander onto a heath, the Three Witches enter and greet them with prophecies. Though Banquo challenges them first, they address Macbeth, hailing him as "Thane of Glamis," "Thane of Cawdor," and that he shall "be King hereafter." Macbeth appears to be stunned to silence. When Banquo asks of his own fortunes, the witches respond paradoxically, saying that he will be less than Macbeth, yet happier, less successful, yet more. He will father a line of kings though he himself will not be one. While the two men wonder at these pronouncements, the witches vanish, and another thane, Ross, arrives and informs Macbeth of his newly bestowed title: Thane of Cawdor. The first prophecy is thus fulfilled, and Macbeth, previously sceptical, immediately begins to harbour ambitions of becoming king.
