What is the princpal appeal of this tragedy? what themes are addressed by sophocles?

There are several themes. One is the rights of women in a world of domineering men. A second is the way in which countries are ruled, emphasizing Creon's belief that the king equals the state. We also see the respect for the gods which Creon ignores and suffers for when he loses his son and his wife. The appeal of this tragedy might be that it was so unique for the time in which it was written, especially with the emphasis on women.
