For some years before the outbreak of World War I, a number of painters in different European countries developed works of art that some have described as prophetic: paintings that by challenging viewers’ habitual ways of perceiving the world of the present are thus said to anticipate a future world that would important break with traditions of representational art that stretched back to the Renaissance.
So fundamental is this break with tradition that it is not surprising to discover that these artists—among them Picasso and Braque in France, Kandinsky in Germany, and Malevich in Russia—are often credited with having anticipated not just subsequent developments in the arts, but also the political and social disruptions and upheavals of and not their break with traditional artistic techniques, that constitutes their chief interest and value.
No one will deny that an artist may, just as much as a writer or a politician, speculate about the future and then try to express a vision of that future through making use of a particular style or choice of imagery; speculation about the possibility of war in Europe was certainly only to the eye. The reformation of society was of no interest to them as artists.
It is also important to remember that not all decisive changes in art are quickly followed by dramatic events in the world outside art. The case of Delacroix, the nineteenth-century French painter, is revealing. His stylistic innovations startled his contemporaries—and still retain that power over modern viewers—but most art historians have decided 1830, as opposed to other artists who supposedly told of changes still to come.
