Answer:
The repetition that Antigone's tomb has become her nuptial chamber, makes the reader lose hope that she will marry and be happy, which leaves everything sad, melancholy and depressive.
Explanation:
Antigone was a girl who was engaged to Creon's son and so she should be happy and anxious for the moment when the wedding would take place, and for the moment when she was in her nuptial chamber. This anxiety about marriage, should make the reader and the audience happy, because something good and happy was about to happen.
However, Creon, who was a king, determined that one of Antigone's brothers, who died attacking the city in which he was born and raised, should not be buried and have a dignified funeral. Whoever dared to bury him would be condemned to death.
At that moment all of Antigone's happiness ended and she decided to disobey Creon and bury her brother. This means that Antigoe is condemned to death even before the wedding. Antigone's death saddens the reader and the audience, and the repetition that her tomb has become her nuptial chamber has caused the mood of sadness and horror to increase more and more.
Mood is the feeling that the author wants to convey with a story.
