In Early Netherlandish painting, from the richest cities of Northern Europe, a new minute realism in oil painting was combined with subtle and complex theological allusions, expressed precisely through the highly detailed settings of religious scenes. The Mérode Altarpiece (1420s) of Robert Campin, and the Washington Van Eyck Annunciation or Madonna of Chancellor Rolin (both 1430s, by Jan van Eyck) are examples.[7]
