Let us travel back to the 15th century and imagine the interior of the workshop of the painter Jan van Eyck: a porter delivers a wooden panel, one assistant grinds pigments, another mixes them with linseed oil, and a third arranges them on palettes. It is in this environment that Jan van Eyck was able to paint The Virgin and Child with Chancellor Rolin, a small-scale work depicting the Virgin Mary seated on a blue cushion embroidered with gold, holding the Christ Child on her lap, facing a man in his sixties who clasps his hands in prayer.
