But the most remarkable thing about prehistoric naturalism is not that it is older than the geometric style, which makes so much more of a primitive impression, but that it already reveals all the typical phases of development through which art has passed in modern times and is not in any sense the merely instinctive, static, a-historical phenomenon which scholars obsessed with geometric and rigorously formal art declare it to be. This is an art which advances from a linear faithfulness to nature, in which individual forms are still shaped somewhat rigidly and laboriously, to a more nimble and sparkling, almost impressionistic technique.
