In Singing of Arms and Men, author Kelley Harness undertakes the first comprehensive study of the seventeenth-century Florentine horse ballets. She demonstrates how these works communicated messages relevant to the occasions for which they were performed, delivered by means of texts sung in styles similar to contemporary opera and punctuated by choreography and dramatic structure. Mock battles fought with swords and pistols animated audiences but also provided visible instances of conflict, which were then interrupted by the sudden arrival of a deus ex machina, who commanded the combatants to instead join forces to defeat a common enemy. The knights then demonstrated newfound cooperation through their creation of choreographed figures danced on horseback in time to music. Documentary evidence confirms that the Medici family expended significant financial and human resources on these one-time events, revealing just how much work it took to appear effortless.
Ultimately, Harness shows how the balletto a cavallo played a crucial role in Medici self-fashioning during the period, and that the 250 noblemen invited to lend their equestrian skills both confirmed their family's relationship to the Medici and were provided a venue for demonstrating critical markers of masculine nobility.
