In the context of this artwork, analyze the Shutters of the Description.
Like in other contemporary Flemish triptychs, the shutters are externally painted in grisaille, depicting two saints. At left is St. James in pilgrimage within a wicked land with a hanged man (perhaps a reference to some episode in the Golden Legend); at right is instead St. Bavo, the patron of Flanders, donating to the poor with his hawk on his left wrist.
One of the characters in the latter panel, the old woman with a child, appears in a drawing attributed to Bosch, now in a San Francisco private collection.
