Edgar Allan Poe (1809-1849) was one of the most diverse writers of the
19th century. While his poems and short stories first gained popularity
in Europe, his fellow Americans appreciated his sharp essays and
merciless literary criticism. His legacy continues until the present day
and transcends the borders of literature, influencing writers of both
fiction and non-fiction as well as artists and even scientists. Poe
himself and many others have often described the literary theory which
underlies all of his work, yet less light has been shed upon how that
theory was formed. Analysing the writer's works in conjunction with the
various scientific, philosophic and literary material that he is known
to have read, Margaret Alterton reconstructs the genesis of the very
fundament of Poe's genius.
