In the centre panel of this triptych four figures are shown at length: the Virgin and Child on a high, triangular backed throne, with Christ holding a goldfinch; St Catherine on the left in a pale-pink dress; a deacon-martyr to the right in red. The left wing contains a nativity scene, with the Virgin lying beside the tightly-wrapped Christ Child in the manger, the ox and ass beyond, two shepherds and Saint Joseph seated in the foreground. The right wing depicts the crucifixion, with the Virgin and Saint John mourning beneath the cross. An Angel of the Annunciation is in the upper part of each wing. The triptych has been described as ‘very mediocre’ and is of inferior craftsmanship. It has been placed in Florence in the school of Bernardo Daddi, but it is not directly from his workshop, where its poor quality would not have been tolerated.
