With both wings closed together, the innovative design of this 14th century triptych is revealed, for below the figures of two bishop saints in the arched upper sections of the outer shutters, a scene of the Adoration of the Magi has been painted. It was unusual for the backs of the wings to be painted with anything other than figures of saints, or a decorative pattern. Yet not only did this outer area contain a scene of importance in the overall visual programme, but it was exceptional in that the narrative extended over both wings.
The continuation of the rocky landscape from one side to another and the pointed arch mouldings around the narrative, give the impression that we are looking through a window at an event that is taking place outside. This is reinforced by the incomplete images of horses on one side and Joseph on the other, which are cut off by the 'window frames'. We are led to believe that we are witnessing the story as it unfolds before us, involving us more intimately, and encouraging us to participate in the adoration of the Christ Child.
