Jan van Eyck (c. 1390–1441) was the supreme master of the Early Netherlandish school and a pioneer of oil painting. His jewel-like precision and luminous detail — above all in the Arnolfini Portrait and the Ghent Altarpiece — astonished all of Europe.
Though he did not invent oil paint, van Eyck perfected it, making possible the deep, glowing realism that defined Northern art.
