3. What is “The Lord of the Flies”? Who names it?

Simon sits alone in the clearing, staring with rapt attention at the impaled pig’s head, which is now swarming with flies. The sight mesmerizes him, and it even seems as if the head comes to life. The head speaks to Simon in the voice of the “Lord of the Flies,” ominously declaring that Simon will never be able to escape him, for he lies within all human beings. He also promises to have some “fun” with Simon. Terrified and troubled by the apparition, Simon collapses in a faint.

Simon's delusions name the pig's head.

The "Lord of the Flies" is the Latin translation for "Beelzebub" or the "Devil". Golding names it. The pig's head on a stick becomes a symbol for the darkness that exists in all of the boys.
