on reverse, concentrically around periphery, behind arc from 6:00 to 11:00, initial letters somewhat worn: .VIVA.HERCVLE. (Long life to Ercole)
 Presumably referring to Ercole I d'Este, duke of Ferrara (born 1431, duke 1471, died 1505), and therefore inscribed between 1471 and 1505, as established by Émile Molinier, Les Bronzes de la Renaissance. Les plaquettes: catalogue raisonné, 2 vols., Paris, 1886: 2:88, no. 502; the legend was incised on both of the known early specimens of the plaquette (the NGA example and one in the Bibliothèque Nationale, Paris). The inscription may not necessarily refer (as Molinier supposed) to a particular one of Ercole's external military victories, however, as much as to the more general factional struggles associated with his accession to the dukedom.
