"The Rime of the Ancient Mariner" is a famous epic poem by Samuel Taylor Coleridge. The poem tells the story of a mariner who kills an albatross, a deed considered a bad omen, during a sea voyage. Following this act, the mariner and his ship face numerous disasters, causing him to deal with guilt and isolation. The story is a reflection on sin, forgiveness, and respect for nature, woven with supernatural elements and vivid imagery.
