Rogier van der Weyden, Last Judgment Polyptych (front and reverse views), 1446-52

The Burgundian chancellor Nicolas Rolin (ca. 1376-1462), one of the richest and most powerful men of the period, commissioned the Beaune Altarpiece for the hospital he had founded to care for the poor as well as the sick in 1443 in Beaune in the old duchy of Burgundy, where the work can still be seen today. The altarpiece was intended for the chapel that stood at the end of the 72-meter-long hospital ward. The patients were to be able to see it across a partition, and its considerable dimensions and composition, clearly distributed over the entire surface of the picture and easily surveyed even from some way off, helped it to meet that requirement. Opened out, the retable shows the Last Judgment, a clear admonition to the sick to remember their own mortality and turn their minds to God. This is easily understandable, since the spiritual care of the sick was as important as their bodily care, and in the thinking of the time only those in a state of spiritual grace could be restored to health.
