Who was the Lord of the Flies?

the Lord of the Flies (Pig's head on a stick) becomes a physical manifestation of the beast, a symbol of the power of evil, and a kind of Satan figure who evokes the beast within each human being. Looking at the novel in the context of biblical parallels, the Lord of the Flies recalls the devil, just as Simon recalls Jesus. In fact, the name “Lord of the Flies” is a literal translation of the name of the biblical name Beelzebub, a powerful demon in hell sometimes thought to be the devil himself.
