The witches ask Macbeth whether he would rather hear it from them or from their masters. Macbeth chooses to have the masters come and explain what they are performing. Once the witches summoned the spirits, thunder was heard and the first apparition was shown as an armored head of a warrior. The apparition tells Macbeth to beware of Macduff. Macbeth responds to the apparition by admitting that Macduff is one of his fears. The second apparition appears as a bloody child. The second spirit tells Macbeth that he must be violent, bold and firm because no man born of woman will harm him (IV, i, 77-81). When Macbeth hears the message of the second apparition he becomes arrogant saying that there is no reason to fear Macduff, but that he will kill him anyway so that he can conquer his fears and sleep well. The last apparition appears as a crowned child with a tree in his hand. He tells Macbeth that he should be brave and proud because he will never be defeated until Birnam Wood moves to Dunsinane Hill (IV, i, 90-95). Macbeth becomes more confident that no one can defeat him because he believes that a forest cannot rise from its roots and fight him at Dunsinane.
