William Golding's Lord of the Flies is not a novel which makes a lot of allusions to mythology or other literary works; however, it is a novel full of biblical allusions.
From the beginning, the island is a lush, idyllic place, untouched--so far--by sin or evil. It is Eden. The boys eat fruit and live a relatively carefree life without recognizing the evil which lurk, the beast that is them (Satan). Simon is the Christ figure, feeding the children and going off alone to face the devil (the Lord of the Flies) and try to save his fellow men--only to be senselessly killed by the very people he was trying to save.
It is hard to miss the constant references to good and evil as well as biblical figures, stories, and concepts in Lord of the Flies.
