Ducat - Anthony Fluvian Transition type

Anthony Fluvian de la Rivière served as Grand Master from 1421 to 1437, a period when the Order was consolidating its naval dominance in the eastern Mediterranean and managing the constant financial strain of maintaining Rhodes against Ottoman pressure. The coinage of his tenure occupies an awkward transitional moment — earlier Hospitaller ducats had adhered closely to the Venetian ducat standard to facilitate trade, and the shift toward a distinctly Hospitaller type was gradual enough that die marriages spanning stylistic conventions are documented for this period.

Attribution to Fluvian's mastership rather than his predecessor Jean de Lastic relies primarily on die study and hoard evidence, not mint records, which survive only fragmentarily for Rhodes.
