What is the importance of the title? Please explain

The Lord of the Flies is the pig's head on the stick but it represents so much more than that. The title of "Lord of the Flies" means Belzebub, the latin name for Satan. The Lord of the Flies speaks to Simon in the voice of a Headmaster. The voice is an extension of the dark side that Golding thinks exists in all of men, or boys in this case. Only Simon , Golding's Christ figure, has the faculties to face this metaphor in its very literal manifestation.
