The last flowering of the medieval art of manuscript illustration took place at the end of the 15th century in Flanders.

But the artists of the Burgundian Court were all anonymous; the invention of the printing-press made hand-written books obsolete; and painting on wood and canvas replaced manuscript illumination. So today almost nothing is known about who painted what, and when. In this programme Thomas Kren, of the University of California, traces for the first time the connections of a masterpiece of medieval art - The Hastings Hours - and throws new light on these last great painters of the Middle Ages.
