decline and is shown by Piggys specs. His glasses with the help of which the fire is started represent the scientific and intellectual power of the society he has been raised. This shows that Piggy's glasses were essential in surviving, without them no fire could be made on the island. Jack states that the beast can take shape in any form, which is kind of showing how the beast can take shape in anybody. When the conch is broken, Jack runs forward screaming that now he can be chief. Looking at the book in the sense of the bible, the Lord of the Flies resembles the devil, just as Simon resembles Jesus. Instead of it being the signal fire it is the fire of savagery. Simon has a discussion with the lord of the flies and it tells him that the beast cannot be killed and it lurks within all.
Piggy's the one who recognizes it and knows how to blow it; he's the one who keeps returning to its power; and they both die at the same time. When Simon has his scene with the pigs head, the Lord of the Flies says to him, Im the beast. One last thing: the conch is definitely associated with Ralph, but it's also associated with Piggy. When the fire starts to burn out of control and one boy goes missing (the one with the big birthmark on the side of his face) this shows that the fire is becoming savage. They are used to make fire with and are therefore a necessity in the hope of rescue as well as surviving in general. Golding describes the making of the fire on top of the mountain using Piggy's glasses as follows: "Ralph moved the lenses back and forth, this way and that, till a glossy white image of the declining sun lay on a piece of rotten wood.
