Chapter Four, entitled "Painted Faces and Long Hair," introduces the concept of masks to the story. The masks become a major symbol that builds in significance throughout the course of the novel. In this particular chapter, Jack toys with the idea of camouflage, like "dazzle paint" (63). Upon creating a mask, Jack felt as though he were looking at an "awesome stranger" (63). The mask becomes a symbol of savagery; wearing one enables Jack to act bolder, fiercer and "liberated from shame and self-conciousness" (64). Jack originally concocts the idea of the masks and paint as a way to conceal himself from the eyes of the pigs, but quickly the masks become much more than camouflage; they liberate the boys from the confines of civilized rules and expectations.
