This act can be interpreted to mean
In William Golding's Lord of the Flies, Jack painting his face can be interpreted to mean regression into savagery. The act of painting his face is symbolic of Jack's descent into savagery and his detachment from the civilised world. The mask that he creates by painting his face allows him to behave in a way that he would not normally behave, thus giving him the freedom to indulge in his most primitive desires. It also marks a physical transformation in Jack's character as he becomes more and more savage throughout the course of the novel.
