Vincenzo is the property manager of Marius’s Venetian palazzo. Marius believes him to be a mortal of great health and excellent intellect. As Marius gathers numerous boys to his palazzo, all of them apprentices, Vincenzo principally governs them. He remains in Marius’s service for many years, never suspecting that his master is a vampire. In time, the Talamasca agent Raymond Gallant becomes aware of Marius’s immortal existence. Gallant infiltrates Marius’s palazzo and questions Vincenzo to a great extent concerning his immortal master, but Vincenzo remains a faithful servant, never revealing too much—and clearly ignorant that he is in service to a blood drinker. At length, when Santino and the Children of Satan attack the palazzo and burn it to the ground, Vincenzo is killed at the front doors.
Vincenzo appears in Blood and Gold (2001). For more perspectives on Vincenzo, read the Alphabettery entries Children of Satan, Marius, Raymond Gallant, Santino, and Talamasca Order.
