At the end of the 18th century, a period of social, political and religious confusion emerged in literature, the Romantic Movement, a movement that emphasized the emotional and personal in reaction to the classical values ​​of order and objectivity. English poets such as William Blake or Percy Bysshe Shelley considered themselves capable not only of writing about everyday life, but also about man's ultimate destiny in an uncertain world. Furthermore, they all claimed to believe in the natural goodness of man and his future. Mary Shelley is a good example, as she questions redemption through the union of human consciousness with the supernatural. Although this movement was well known, none of the British writers actually acknowledged its membership; “.”1 But the main theme of the assignment is the narrative voice in these romantic works. The narrator is the person chosen by the author to tell the story to the readers. Traditionally, the person telling the story was the author. But things were changing; the concept of the unreliable narrator was starting to get used to give the story an atmosphere of suspense. “The effect of the narrator's telling of this story on the reader, as well as the sailor's telling on the wedding guest, makes the narrative itself fundamental (as in Frankenstein)” (Dr. Michael Rossington). Therefore, this essay will talk about the different narrators present in both literary works and its narrative structure Mary Shelley and Samuel Taylor Coleridge are two recognized writers of the Romantic Era The influence of Coleridge's The Rime of the Ancient Mariner is reflected in Shelley's Frankenstein in terms of narrative structure, literary techniques and themes. For example, bo...... in the center of the paper ......explain the situation to the Ancient Mariner. Furthermore, the way in which the dialogue is presented, does that the structure seems more like the script of a play. The structure of the poem is a key feature in the exposition of the theme, since by telling the story as a personal experience, it helps the reader to understand the moral and the theme intended as a warning for people. This essay has argued that both works, Frankenstein and The Rime of the Ancient Mariner have similarities in terms of themes and narrative structure. Shelley and Coleridge used various narrators to tell their stories, and in doing so,14 Furthermore, both works are structured in the same form, with the frame narrative, a story within a story, providing a framework of verisimilitude to an unlikely tale . In short, The Rime of the Ancient Mariner is a constant presence in the novel Frankenstein.
