This essay argues that the collapse of Empire in Conrad’s Heart of Darkness is troped as the erosion of textuality. Five key instances of this textual collapse occur in the novel: the maps Marlow reads as a child, the accounting books, the seaman’s manual, the Kurtz Report and the Company papers. There are also a few minor instances of similar textual collapses, which also come to attention here. The essay notes that in each case the text’s significance is lost or altered in specific ways, and this contributes to the erosion of the authority of the text.
