A metaphor is figurative language that compares one thing to another by equating the two things. Several metaphors are used in the book that refer to the boys. When the boys make the first fire, even Ralph rushes away to join in the excitement, leaving Piggy behind. He is compared to a parent with the following metaphorical description: "Then, with the martyred expression of a parent who has to keep up with the senseless ebullience of the children, he picked up the conch." In chapter 5, when the boys have run away at the end of the meeting, Piggy says, "If you don't blow, we'll soon be animals anyway," comparing the boys to mere unthinking creatures. In chapter 7, Ralph's habit of thinking during meetings is compared to playing chess, but he is described as someone who "would never be a very good chess player." This does not refer to his actual ability to play chess but rather to strategize while others were watching. In chapter 8, when the boys come to Ralph to steal fire, "demoniac figures with faces of white and red and green rushed out howling." This metaphor compares the boys to demons. When Ralph confronts Jack at Castle Rock, he shouts, "You're a beast and a swine." These are insults, of course, but they are metaphors that compare Jack to an animal.
In chapter 5, after the assembly, when Ralph is talking about stepping down as chief, Ralph refers to Piggy, Simon, and himself by saying: " Fat lot of good we are, said Ralph. "Three blind mice." In my edition it is on page 108.
Later in the novel, chapter 8 page 164, Golding refers to Simon as a "small brown image, concealed by leaves.
