The so-called Flemish Primitives, a group of 15th-century painters from the Burgundian Netherlands, acquired their name in the 19th century. Among them were world-famous artists such as Rogier van der Weyden, Hans Memling, the brothers Van Eyck, and Hugo van der Goes. Their masterpieces, oil paintings minutely detailed in luminous colour, are a high point of Western European art, which, together with the Italian Renaissance paintings, laid foundations for modern art. This scholarly in-depth analysis focuses on the artistic, religious and social significance of their art, as well as how the paintings themselves were collected, evaluated and studied over the centuries.
