But he plays no such part. When next we see him, on the last day of his life, we find that he has yielded to evil. The Witches and his own ambition have conquered him. He alone of the lords knew of the prophecies, but he has said nothing of them. He has acquiesced in Macbeth's accession, and in the official theory that Duncan's sons had suborned the chamberlains to murder him. Doubtless, unlike Macduff, he was present at Scone to see the new king invested. He has, not formally but in effect, 'cloven to' Macbeth's 'consent'; he is knit to him by 'a most indissoluble tie'; his advice in council has been 'most grave and prosperous'; he is to be the 'chief guest' at that night's supper. And his soliloquy tells us why: Thou hast it now: king, Cawdor, Glamis, all, As the weird women promised, and, I fear, Thou play'dst most foully for't: yet it was said It should not stand in thy posterity, But that myself should be the root and father Of many kings. If there come truth from them-- As upon thee, Macbeth, their speeches shine-- Why, by the verities on thee made good, May they not be my oracles as well, And set me up in hope? But hush! no more. This 'hush! no more' is not the dismissal of 'cursed thoughts': it only means that he hears the trumpets announcing the entrance of the King and Queen. His punishment comes swiftly, much more swiftly than Macbeth's, and saves him from any further fall. He is a very fearless man, and still so far honourable that he has no thought of acting to bring about the fulfilment of the prophecy which has beguiled him. And therefore he has no fear of Macbeth. But he little understands him. To Macbeth's tormented mind Banquo's conduct appears highly suspicious. _Why_ has this bold and circumspect[237] man kept his secret and become his chief adviser? In order to make good _his_ part of the predictions after Macbeth's own precedent. Banquo, he is sure, will suddenly and secretly attack him. It is not the far-off accession of Banquo's descendants that he fears; it is (so he tells himself) swift murder; not that the 'barren sceptre' will some day droop from his dying hand, but that it will be 'wrenched' away now (III. i. 62).[238] So he kills Banquo. But the Banquo he kills is not the innocent soldier who met the Witches and daffed their prophecies aside, nor the man who prayed to be delivered from the temptation of his dreams.
