The Vivarini were a family of Venetian painters whose prolific workshop specialized in large multi-tiered altarpieces for churches throughout the Veneto region. This relatively small triptych was likely intended for private devotion. The kneeling nun, dressed as a member of the Dominican Order, probably represents the patron. Bartolomeo’s debt to the Paduan master Andrea Mantegna is especially evident in the rendering of the landscape and the figure of the Madonna in the Nativity scene. Although the frame is not original, it conveys the decorative ornamentation typical of the Vivarini.
