Libretto of the entertainment “La Battaglia del Ponte” performed on the Arno River during celebration of the Feast of Saint James, on 25 July 1618. The designer of the festival machinery was Giulio Parigi, designer also of floats built for Ferdinando Saracinelli’s “Arrivo d’Amore in Toscana” enacted on the same feast day in 1615, and for Andrea Salvadori’s “Battaglia tra tessitori e tintori” performed in 1619 (those floats are documented in prints by Jacques Callot). Regrettably, no visual documentation survives of Parigi’s apparati for “La Battaglia del Ponte”.
