The 'Rime of the Ancient Mariner' recounts the tale of a mariner who stops a wedding guest to share his harrowing story of survival after killing an albatross, which brings misfortune to his ship. As the tale unfolds, the mariner learns to appreciate nature, endures a curse with his crew, and ultimately seeks redemption through his experience. The poem explores themes of crime, punishment, and the relationship between humanity and nature, structured in seven parts with a distinctive rhyme scheme.
