Why does Sir Gawain and The Green Knight begin with mentions of Troy and Rome? Why are Aeneas (Troy) and Romulus (Rome) mentioned before King Arthur (Britain)? Aeneas, Romulus and King Arthur are all literary characters with a “historical” significance. Is there a comparison that is being made between King Arthur and his Knights and the conquering forces of Aeneas and Romulus? Does the Green Knight then represent the natural force of Britain that King Arthur and his knights are conquering or something else?
