 			&lt;p&gt;&lt;a href="https://standardebooks.org/ebooks/edgar-allan-poe"&gt;Edgar Allan Poe&lt;/a&gt; is one of the primary figures of American nineteenth-century literature. His writing was heavily influenced by Romanticism ideals of emotion and feeling, and although mostly known for his Gothic-tinged horror, his tales jump between many different genres, including science-fiction, satire, humor, mystery, and even early detective fiction.&lt;/p&gt;
