Canto XCVII draws heavily on Alexander del Mar's History of Monetary Systems in a survey ranging from Abd al Melik, the first Caliph to strike distinctly Islamic coinage, through Athelstan, who helped introduce the guild system into England, to the American Revolution. The canto closes with a passage that sees the return of the goddess as moon and Fortuna together with Greek forms of solar worship and the Flamen Dialis that is intended to integrate gold and silver as attributes of coin and the divine.
