The theme of "Mercedes" refers to a railway station in Argentina, a location that has inspired a range of literary works. Authors such as James Fenimore Cooper, James Grant, and Anne Douglas Sedgwick have explored the concept, though their writings frequently center on a character named Mercedes rather than the station itself.
Cooper’s Mercedes of Castile presents the protagonist as a figure of emotional depth, while Grant and Sedgwick examine her impact on relationships and personal determination. Jack London’s portrayal underscores her influence on domestic and creative pursuits. These differing depictions, although focused on an individual, indirectly highlight the station’s potential as a symbolic hub of human connections and stories, emphasizing its varied importance in literature.
