First put the title aside. No one really knows what "tales of the grotesque and arabesque" means. Poe himself indicated he intended more than the usual meanings of bizarre and fanciful writing; his theories on the purpose of stories such as his were complex. Also put aside for now any idea of these being early horror stories. Some of them may or may not represent that genre. But reading them with that modern concept in mind would probably lead to your disappointment. For the stories collected in Tales of the Grotesque and Arabesque, like his other--often more famous--individual stories are more variable in theme and style than you might expect.
