Marmion, Simon (c. 1422–1489)

French painter and miniaturist of the Franco-Flemish School. Active in Amiens, Valenciennes, and Tournai, he illuminated manuscripts for Philip the Good, Duke of Burgundy.

He painted panels illustrating the Life of St Bertin (1459) for the abbey of St-Omer, southeast of Calais (St Bertin was a missionary in the region in the 7th century). Several panels are lost but there are parts in the Staatliche Museum, Berlin, and in the National Gallery, London, showing a notable delicacy of style.
