Francesco was the alias used by one of Rosanna Calvierri's male children who escaped the silence that fell over Saturnyne.

Francesco was the eldest of Rosanna's male children. In Venice in 1580, he wore a perception filter and helped his mother capture girls to be transformed into mates for his brothers. After Amy Pond escaped from his mother's "school", he chased her. Rory Williams insulted his mother, distracting him, and tried to fight him. Returning to his true form, Francesco was killed when Amy reflected light from the sun onto him using a mirror, saving Rory in the process. (TV: The Vampires of Venice)
