"Immediately the thing sounded. A deep harsh note boomed under the palms and spread through the intricacies of the forest" (Golding pg 17). The conch symbolizes civilization in a way it is used to call all of the children to the meeting and it represents the leader of the boys with the booming sound it makes.
Beast Symbolizes fear
"His specs-use them as burning specs (Golding 40)." The glasses represent the technology role in civilization as a tool that the boys use to survive.
Pig's Head Symbolizes reality
"There was a ship. Out there. You said you'd keep the fire going and you let it out!" (Golding 70). The fire represents their rescue and return back to civilization, however it is sabotaged by jack when he chooses to hunt over his role in their small society.
Painted Faces Symbolizes Savagery
"The vivid horror of this, so possible and so nakedly terrifying, held them all silent"(Golding 85) The beast represents fear among the boys even though it doesn't exist because the boys need to believe in something in order to forget about their fear of staying on the island forever.
"You are a silly little boy', said the lord of the flies, 'Just an ignorant, silly little boy (Golding 143). The pigs head represents the reality in society where we find things we believe in or fear turn out to be not as we seem. In lord of the flies reality is revealed to Simon when he finds that the real beasts are the boys themselves.
"come on! I'll creep up and stab-the mask compelled them. (Golding 64)." The painted faces represents the growing savagery that has taken over the boys. Even if they get off the island they will never be the same. Instead of turning keeping society jack deflects it when masking his innocence in paint.
