Faulkner's "A Rose for Emily" is rooted in Gothic structure and style, but it is actually part of a sub-genre of the Gothic known as "Southern Gothic," which began its evolution into a literary style in the early 1900s.
Elements of mystery, darkness, and the supernatural were popular and conventional components of Gothic style. In other works of Gothic literature, we also see an examination of the darker and more grotesque aspects of the human psyche; however, most traditional Gothic writers like Poe and Shelley set their stories amidst dank dungeons and cob-web infested castles.
Writers of the Southern Gothic differed in that they were much more interested in exploring the darker and more unsavory aspects of human psychology through their writing. Individuals suffering from various mental illnesses or individuals who were seen as anti-social outsiders were often character subjects of the Southern Gothic.
"A Rose for Emily" examines the anti-social behavior of Miss Emily Grierson and the mystery surrounding both her and her home. Miss Emily's alienation from society is only the tip of the iceberg, though, as it is later revealed to the reader that she was a necrophiliac. This is both disturbing and grotesque. Despite the town's realizations about Miss Emily and what she was hiding, her character is still very much shrouded in mystery.
While Faulkner's "A Rose for Emily" examines the psychologically disturbing conventions of the Southern Gothic, traditional aspects of the Gothic genre can be found in the text as well, specifically with regard to Miss Emily's house. The house is crumbling and in the midst of decay.
Homer Barron, Emily's lover and victim, is instrumental to the story's narrative as well. He is an outsider, in his own way, as he is a northerner and is largely distrusted by the other townspeople. Because Homer describes himself as not "a marrying man", he is symbolic of change and modernity, while Emily and the townspeople of the South more or less represent tradition. The change that Homer brings to the town and to Miss Emily can be construed as dangerous, which can be seen in his horrific fate.
The various Gothic elements of the story are strewn throughout and can be seen in the character depictions, the collective and individual psyches of townspeople, and in Miss Emily's house itself.
