How does Coleridge's purpose is clearly in “The Rime of the Ancient Mariner”, which demonstrates salvation, and the power of sympathetic imagination.

As soon as the mariner kills the albatross, the story becomes a tale of sin and redemption. Both the mariner and his crew are damned. The supernatural takes over to punish and teach the mariner the folly of his ways. Coleridge uses ghost sailors, storms, thirst, fire...to teach the mariner about the sanctity of life. It isn't until the mariner appreciates the slimy sea snakes as much as his own life that there is salvation to be had. His trip to redemption becomes the landscape of the supernatural imagination. The mariner experiences the wonder and power of the universe that he was previously blind to.
