PORTRAIT OF A GIRL WITH A DOG AND A MISSAL, circa 1610 Roman artist (Ottavio Leoni?), Italian school. This young woman was initially identified as Margarita Aldobrandini, niece of Pope Clement VIII, although there is no data to confirm this. The luxury of the suit, the presence of the dog as a symbol of fidelity and the missal could indicate that it is a portrait of engagement.
