In the drama Antigone, the plot, character, and diction are not only the key elements, but they are all dependent upon one another.
In Antigone the plot is quite obvious. After Antigone's father passed away, her two brothers, Eteocles and Polynices, had agreed to share the kingdom between them and reign alternately year-by-year. This obviously didn't work out because those in newfound power often become corrupted and greedy. The siege continued and the brothers finally agreed that they would decide their quarrel with a single combat. They fought and fell by each other's hands. The armies then renewed the fight, and at last the invaders were forced to yield, and fled, leaving their dead unburied. Creon, the uncle of the fallen princes, now become king, caused Eteocles to be buried wit distinguished honor, but suffered the body of Polynices to lie where it fell, forbidding every one on pain of death to give it burial. Antigone, the sister of Polynices, heard with indignation the revolting edict which consigned her brother's body to the dogs and vultures, depriving it of those rites which were considered essential to the repose of the dead. Unmoved by her affectionate but timid sister, and unable to proctor assistance, she determined to brave the hazard, and to bury the body with her own two hands. She was caught in the act, and Creon gave orders that she should be buried alive. Her lover, Haemon, the son of Creon, unable to avert her fate, would not survive her, and fall by his own hand. .
After watching the drama it is quite evident that the plot would not have been so great if it weren't for the characters. In a drama, it isn't exactly the plot itself that makes it a drama; rather how the characters respond to what is going on that makes the drama so interesting. If Antigone would have not been so persistent in defending her brother throughout the drama, the whole drama would have fallen apart.
