The man is fascinated by this woman. He has a burning love for her, but it seems the woman does not reciprocate his feelings. He compares her to ice.
How comes it then that this her cold so greatis not dissolved through my so hot desire,But harder grows the more I her entreat?
This line further enforces the idea of the man's love. It also adds a detail previously unknown to the readers; that he has made efforts to get her to fall in love with him.
An extended metaphor is seen throughout the poem. It is used to add to the anguish of the desire the narrator is feeling. The metaphors used throughout the poem is fire and ice. The narrator compares his love and desire for the woman to fire, and hers to ice, as she is uninterested in his advances and turns a cold shoulder to him. This helps the narrator convey the difference in their love for one another or lack thereof.
The Turn in the story occurs in lines 5-7. Before the Turn happens, the narrator is describing his burning love for a woman that is not returned. In the Turn, while the narrator described the woman as being colder, he can't help but fall more in love with her. He knows he should be feeling dejected, but instead his love and affection burns brighter and with more intensity.
What more miraculous thing may be told,That fire, which all things melts, should harden ice
The man is distraught that his love should not be returned by the woman. The more the man shows affection with his burning love, the colder the woman grows towards him.
Such is the power of love in gentle mind,That it can alter all the course of kind.
The man is distraught and in disrepair for something he loves so, that doesn't hold the same affection. Love can change a person in many ways. This is seen throughout the story, especially in the end line. Love is not always a tow-way street.
