But the clever thing about the prophecies is that we are left to decide how much what happens in the play was foretold in the Witches’ prophecy and how much was a result of the course of action Macbeth decided on, once he had knowledge of the prophecy. Indeed, the King even wrote a book about it, Daemonologie, which had been published in 1597, six years before he came to the English throne. One of the reasons Shakespeare may have been drawn to the story of Macbeth is that, as well as speaking to King James I’s Scottish blood, it also played to his interest in witchcraft, black magic, and the supernatural. It’s true that the Witches are clearly meant to be supernatural, and their prophecies are supposedly founded on – well, on their witchcraft. It’s worth stopping to consider and analyse the role of prophecy in Macbeth. Holinshed’s King Duncan is a weak and feeble ruler, who has unfairly named his own son Prince of Cumberland (and thus heir to the throne), thwarting Macbeth’s own (just) claim to the throne, through his wife’s previous marriage and her son by her first husband. The Three Witches appear in Holinshed, but as ‘nymphs or fairies’, suggesting beautiful young women rather than old, ugly hags. The plot of Shakespeare’s Macbeth is a combination of two stories: the story of Macbeth and the story of the murder of King Duffe by Donwald and his wife, which Shakespeare read about in Raphael Holinshed’s Chronicles. Where did Shakespeare get the story from, then, and what did he change? The real Macbeth killed Duncan in battle in 1040 and Macbeth (or Mac Bethad) actually went on to rule for 17 years, until he was killed and Macbeth’s stepson, known as Lulach the Idiot, became king (though he only ruled for less than a year – then Malcolm, as Malcolm III, took the crown). His wife was real too, but Lady Macbeth’s real name was Gruoch and Macbeth’s real name was Mac Bethad mac Findlaích. Macbeth was a real Scottish king, although he was somewhat different from the ambitious, murderous creation of William Shakespeare.
