Final answer:
Edgar Allan Poe, who lived from 1809 to 1849, remains influential due to his pioneering gothic style and his intense emotional storytelling, as well as the psychoanalytical ties between his life experiences and his literary themes.
Step-by-step explanation:
Edgar Allan Poe lived from 1809 to 1849, and his influence persists due to his distinctive literary style and thematic pioneering in gothic and macabre literature. Marie Bonaparte's psychoanalytical study of Poe ties his writing deeply to the loss of his mother at an early age, suggesting his works are a reflection of unconscious desires and unresolved personal trauma.
In the broader perspective, Poe's influence is due to his talent in crafting engrossing narratives, his development of the modern detective story, and his poetic principle of creating an intense emotional effect in his art. This connection between the artist's life, particularly Poe's, and his work offers insights into the psychoanalytical and thematic content that can prove valuable in literary studies.
