<span>Shelley might resort to several techniques to create a Gothic atmosphere. Firstly, it might be said that she uses the 1st person to let "the monster" retell its story. The book is also full of detailed descriptions such as Frankenstein lab, characters and even the voyage through freezing water. She places with contrasts such as cold and hot, light and dark, etc. She also plays with the physical and phycological aspects of each character for the reader to get a clear portrayal of each of them. </span>
The correct answer is that these lines talk about the immortality of art.
Ode on a Grecian Urn by John Keats is often interpreted as the celebration of art and its immortality. The figures depicted on the urn have passed long before the narrator examines the urn on which their lives were depicted. Even though they perished their story has been preserved on the urn, and in a sense they have become immortal through the art, which is that which remains long after we are gone.
In my opinion, those lines are: "<span>Too weak, for all her heart's endeavour, To set its struggling passion free From pride, and vainer ties dissever." At this moment, Porphyria confesses her love for the speaker. But he is on the verge of doubting it because he thinks that she is too weak to give herself entirely to him, and because she is obviously unwilling to cut those "vainer ties". He doesn't really explain what these ties are and why they are vain. Maybe he has low self-confidence and therefore thinks that he is not worthy of her. Anyway, the following lines ("But passion...") function as a counterpoint because she actually gave up a jolly party and came in the stormy night to the cottage just to be with him - which probably means that she really cares about him. But it doesn't neutralize his initial doubt.</span>
