"From the various contemporary accounts we glean the names of the most famous courtesans: Beatrice of Ferrara, Imperia of Rome, Angela del Moro, Camilla of Pisa, Tullia d’Aragona, Alessandra of Florence, Gaspara Stampa and, of course, the most famous, Veronica Franco. Each of these remarkable women has a wonderful and interesting personal story."
