The lengthy poem 'The Rime of the Ancient Mariner' exalts the Romantic movement of the end of the eighteenth century. It was composed following a meditative walk through the port of Watchet on the Bristol Channel and based on a dream about a ghost ship crewed by lost souls that one of Samuel Taylor Coleridge's friends had shared with him. With hypnotic musicality and powerful symbolism, its narration, like an oracle, tells of the mysterious voyage through the waters of a crime and its punishment towards a destination of storms, penitence and purification. All this is caused by the killing of an albatross, a sign of good fortune, at the hand of a strange sailor, and it will unleash nature's fury, a battle between the forces of good and evil.
