In order to discuss our problem I propose to adopt a definition of art as an ensemble of man-made objects of specific character, of materials, tools and institutions, of people—those who produce and those who commission or look at works of art—and of techniques and skills mastered by the artists. Art—so broadly understood—has no sharp limits, it is an area connected by hundreds of links with the whole of social, economic, intellectual and spiritual life. It is exposed to various disturbances since any one occurring in those other areas with which art is connected must of necessity affect art and its development to a greater or smaller degree. Lack of demand for some kind of artistic products must lead to the extinction of the corresponding kind of production. For instance, images of saints disappeared in those parts of Germany which adopted the Reformation. One can say in general, that, since various factors of social and economic character influence the life of art, it must reflect the results of those crises which affect social, political or economic life, although the way art reacts on various disturbances may be varied. It may seem natural that in a period of unemployment and of high prices society cannot afford to devote as much money to invest in the goods of culture as it does in times of prosperity, and often it is so indeed.
