Oedipus Rex (Oedipus The King) Is yet another story that can be related to The Merchant of Venice. The idea of "fate" connects these two stories together.
Oedipus Rex is a story about the struggle between Oedipus and the fate that was in front of him. He attempts to fight it and change his fate but is unsuccessful.
This is similar to the fate of Shylock and Antonio. They were from opposing religions and their religions naturally hated each other. This brought them to having the feud and becoming rivals.
Fate affects these two stories differently. Oedipus Rex ends in tragedy while The Merchant of Venice has a more peaceful ending. However, this fate shows up during the story and shows that you can attempt to change fate, but will not be successful.
