Satan/Seyton

• "Seyton, I am sick at heart / When I behold - Seyton, I say! - This push / Will cheer me ever, or disseat me now... bring me my armour and send out more horses; skirr the country round; / Hang those that talk of fear" 5:3
• The audience would not fail to notice the name of Macbeth's servant, and the implications this has. The question is whether Macbeth is merely calling for his servant, or whether Shakespeare's implication is that he is calling on the devil? Incidentally, we do not hear anything from the character of Seyton until the latter stages of the play.
• If he had been introduced before Macbeth became a murderer, it is possible that the audience would not have made the link between Macbeth and the devil. His actions throughout the play ensure he would have been damned, so Seyton's instruction at this point serves as an interesting structural device used by Shakespeare, in order to highlight the fact he is doomed to spend eternity in the fiery furnace.
