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)
However, over the course of his stay in Africa, Kurtz becomes corrupted. He takes his pamphlet and scribbles in, at the very end, the words "Exterminate all the brutes!" He induces the natives to worship him, setting up rituals and venerations worthy of a tyrant. By the time Marlow, the protagonist, sees Kurtz, he is ill with jungle fever and almost dead. Marlow seizes Kurtz and endeavors to take him back down the river in his steamboat. Kurtz dies on the boat with the last words, "The horror! The horror!" Kurtz ultimately was changed by the jungle. At first he wanted to bring civilization to the natives, as his painting shows, but in the end he changed to wanting to "exterminate all the brutes!"
