A master of the macabre and mystery, this 19th-century writer revolutionized Gothic literature with dark tales and disturbing psychological atmospheres. His narratives explore themes such as death, madness, and the abyss of the human mind, marked by poetic and intense language. An emblematic work, like a poem about an obsessive raven, became a symbol of his melancholic genius. His legacy endures as a cornerstone of modern horror and detective fiction.
