a medium was a significant development, allowing artists far greater manipulation of paint. The 16th-century art historian Giorgio Vasari claimed van Eyck invented the use of oil paint; a claim that, while exaggerated, indicates the extent to which van Eyck helped disseminate the technique. Van Eyck employed a new level of virtuosity, mainly from taking advantage of the fact that oil dries so slowly; this gave him more time and more scope for blending and mixing layers of different pigments, and his technique was quickly adopted and refined by both Robert Campin and Rogier van der Weyden. These three artists are considered the first rank and most influential of the early generation of Early Netherlandish painters. Their influence was felt across northern Europe, from Bohemia and Poland in the east to Austria and Swabia in the south. A number of artists traditionally associated with the movement had origins that were neither Dutch nor Flemish in the modern sense. Van der Weyden was born Roger de la Pasture in Tournai. The German Hans Memling and the Estonian Michael Sittow both worked in the Netherlands in a fully Netherlandish style. Simon Marmion is often regarded as an Early Netherlandish painter because he came from Amiens, an area intermittently ruled by the Burgundian court between 1435 and 1471. The Burgundian duchy was at its peak influence, and the innovations made by the Netherlandish painters were soon recognised across the continent. By the time of van Eyck's death, his paintings were sought by wealthy patrons across Europe. Copies of his works were widely circulated, a fact that greatly contributed to the spread of the Netherlandish style to central and southern Europe. Central European art was then under the dual influence of innovations from Italy and from the north. Often the exchange of ideas between the Low Countries and Italy led to patronage from nobility such as Matthias Corvinus, King of Hungary, who commissioned manuscripts from both traditions. The first generation were literate, well educated and mostly from middle-class backgrounds. Van Eyck and van der Weyden were both highly placed in the Burgundian court, with van Eyck in particular assuming roles for which an ability to read Latin was necessary; inscriptions found on his panels indicate that he had a good knowledge of both Latin and Greek. A number of artists were financially successful and much sought-after in the Low Countries and by patrons across
