The Renaissance art historian, Giorgio Vasari, said that the art of oil painting came from northern Europe and the person who invented it was the famous Flemish painter Jan van Eyck. Artists from the areas of modern Belgium and the Netherlands were the first artists to make oil painting their usual method of painting. This trend spread to other parts of Northern Europe. A famous painting called the "Portinari Altarpiece" by Hugo van der Goes arrived in Florence in the 1470s at a time when Leonardo da Vinci was young. Oil paintings at this date were usually done on wooden panels, in the way that tempera pictures were.
