A frame story is a story within another story. For example, if you have seen the movie TItanic, there is the story of the crew that has found the shipwreck of the Titanic, and then the story of Rose and her romance with Jack told by Rose as a much older woman. One story takes place in the present, while the other is a remembrance. What are the two stories being told in “Part the First” in “The Rime of the Ancient Mariner”?
