Rowling once said she adored Shakespeare’s Macbeth, and that it inspired the Harry Potter books, particularly the scene of Macbeth meeting the three witches. Shakespeare’s three witches, in turn, are often thought to have their roots in both the Greek Fates and the Norse Norns—three women who spin the threads of fate at the foot of Yggdrasil, the World Tree. Witches, witches, witches. In Blake’s Three Dark Crowns, three witch-sisters must fight to the death for the right to be queen—one is an elemental, one a poisoner, one a naturalist. This is brutal, bloody witch-fantasy at its best.
