Luisa or Luigia Sanfelice (1764–1800) was an Italian aristocrat who was executed by Ferdinand I of the Two Sicilies because of her involvement with the French-backed Parthenopean Republic during the French Revolutionary Wars, although Sanfelice was largely apolitical.[1] As she was generally regarded as the innocent victim of circumstances, she became a legendary figure who was widely portrayed in popular culture. During the nineteenth century she was often depicted as a gentle and naïve beauty whose story closely resembled that of the fictional Fioria Tosca,the heroine of the Puccini opera Tosca.[2]
