what is the significance of the court scene...?

In the trial scene, we can see the conflict of idea of judgment of two religions. According to Judaism (Jews religion), justice means punishing the bad people. So, Shylock feels that he has suffered and he must get an eye for an eye. Eye for an eye or pit for a pit is the main idea of justice according to Jews religion. So, Shylock wanted this kind of justice and he wanted the flesh from the body of Antonio because he felt that it is the exact justice for him after suffering a lot of insults from all the Christians including Antonio.

On the other hand, Christianity has a softer approach to a justice and revenge. One famous idea of Jesus Christ is that if someone then put your right chick in front of that person. Christianity gives a lot of important in forgiving and mercy. Shakespeare has tried to show that the idea of justice of Christianity is better than the idea of justice of Judaism. So, Shakespeare has shown that Shylock became a Christian and this way Shylock got saved.

That trial seen is the fight between Portia and Shylock. All other characters watched the fighting between them. Shylock thought that he had won the trial and no one could have stopped him from taking revenge against Antonio. He was so sure that she started to celebrate very early and others could understand that he was a very bad person who did not care for humanity. On the other hand, Portia was a very smart person and she was determined to save Antonio.

The trial scene is a memorable one because of the strong dialogues from Shylock and from Portia. Some of the dialogues has become very popular and are seen common among the English people.
