A great deal of James Branch Cabell's work has focused on the Biography of the Life of Manuel, the story of a character named Dom Manuel and his descendants through many generations. The biography includes a total of 25 works that were written over a 23-year period. Cabell stated that he considered the Biography to be a single work.
The themes and characters from Jurgen make appearances in many works included in the Biography. Figures of Earth tells the story of Manuel the swineherd, a morally ambiguous protagonist who rises to conquer a realm by playing on others' expectations-his motto being Mundus Vult Decipi, meaning "the world wishes to be deceived." The Silver Stallion is a loose sequel to Figures of Earth that deals with the creation of the legend of Manuel the Redeemer, in which Manuel is pictured as an infallible hero, an example to which all others should aspire; the story is told by Manuel's former knights, who remember how things really were and take different approaches to reconciling the mythology with the actuality of Manuel.
Many of these books take place in the fictional country eventually ruled by Manuel, known as "Poictesme." It was the author's intention to situate Poictesme roughly in the south of France.
