The panel with the Nativity, together with the one depicting Saint John the Baptist, constituted the lower register of a polyptych, now dismembered, which originally featured Saint Martin in the lower left side and a Christ of Sorrows between the two panels of an Annunciation in the upper register. The traditional attribution of the polyptych to Francesco Morone accurately identifies its cultural factors, but does not resolve the question about the autography of the panels, which only partially reveal the artist's finesse of execution.
