Charles Marlow
Marlow's name may be inspired by the Elizabethan playwright Christopher Marlowe. Conrad's father was a translator of William Shakespeare who doubtless would have known of Marlowe's work as well. Some intertextual interpretations of "Heart of Darkness" have suggested that Marlowe's "The Tragical History of Doctor Faustus" may have influenced Conrad. Charles Marlow describes a character as a "papier-mache Mephistopheles", a reference to the Faust legend. Marlow's and Kurtz's journey up the Congo River in "Heart of Darkness" also has similarities to another work by Marlowe, "Dido, Queen of Carthage", in which Aeneas is stranded on the shore of Libya and meets the African queen Dido.
Kurtz (Heart of Darkness)
Kurtz's mother was half English, his father was half French and thus "All Europe contributed to the making of Kurtz.” As the reader finds out at the end, Kurtz is a multitalented man—painter, musician, writer, promising politician. He starts out, years before the novel begins, as an imperialist in the best tradition of the "white man's burden". The reader is introduced to a painting of Kurtz's, depicting a blindfolded woman bearing a torch against a nearly black background, and clearly symbolic of his former views. Kurtz is also the author of a pamphlet regarding the civilization of the natives.
The presence of his admirer, the Russian "Harlequin", and what he reveals about Kurtz in his adulatory descriptions of him raises questions about Kurtz's actual beliefs and the sincerity of his progressive views.
