Look at these pictures and at the Italian again, and another obvious difference is apparent. The Flemish pictures are on the whole much smaller. This is a fact full of significance. In the sunny South the artists spent their best energies in covering large spaces of wall with frescoes; in the damp climate of the North they were obliged to paint chiefly upon panels. The conditions of their climate were no doubt what led to the discovery of the Van Eyck method (described under 186), the point of which was a way of drying pictures rapidly without the necessity of exposure to the sun. It was a method only applicable to work on a small scale, but it permitted such work to be brought to the highest finish. This precisely suited the painstaking, patient men of the Low Countries. Hence the minuteness and finish which characterise their work. Moreover, "every charm that can be bestowed upon so small a surface is requisite to intensify its attractive power; and hence Flemish painters developed a jewel-like quality of colouring which remained peculiar to themselves." ... Further, the Van Eyck method, requiring absolute forethought and forbidding any alterations, tended to a set of stock subjects treated more or less in the same way. "Thus the chief qualities of the Flemish School may be called Veracity of Imitation, Jewel-like richness of Colour, perfection of Finish, emphasis of Character, and Conservatism in design. These indeed are virtues enough to make a school of art great in the annals of time, even though they may never be able to win for it the clatter of popular applause. The paintings of Flanders were not, and were not intended to be, popular. Flemish artists did not, like the Italians, paint for the folk, but for the delight of a small cultured clique."[29]
