 Pigs have been brought into literature for varying reasons, ranging from the pleasures of eating, as in Charles Lamb's "A Dissertation upon Roast Pig", to William Golding's "Lord of the Flies" (with the fat character "Piggy"), where the rotting boar's head on a stick represents Beelzebub, "lord of the flies" being the direct translation of the Hebrew בעל זבוב, and George Orwell's allegorical novel "Animal Farm", where the central characters, representing Soviet leaders, are all pigs.The pig is used to comic effect in P. G. Wodehouse's stories set in Blandings Castle, where the eccentric Lord Emsworth keeps an extremely fat prize pig called the Empress of Blandings which is frequently stolen, kidnapped or otherwise threatened.Quite a different use is made of the pig in Lloyd Alexander's fantasy books "The Chronicles of Prydain", where Hen Wen is a pig with foresight, used to see the future and locate mystical items such as The Black Cauldron.
