Rousseau’s ideas were in the air; he only expressed what many of his contemporaries knew, namely that they were faced with a choice and had to decide… - Arnold Hauser

As an artistic style, mannerism conformed to a divided outlook on life which was, nevertheless, spread uniformly all over Western Europe; the baroque is the expression of an intrinsically more homogeneous worldview, but one which assumes a variety of shapes in the different European countries. Mannerism, like Gothic, was a universal European phenomenon, even if it was restricted to much narrower circles than the Christian art of the Middle Ages; the baroque, on the other hand, embraces so many ramifications of artistic endeavour, appears in so many different forms in the individual countries and spheres of cultures, that it seems doubtful at first sight whether it is possible to reduce them all to a common denominator.

The new Christian ideal of life did not at first alter the outward forms of art, but did alter its social function.

We do not exactly know the sociological reason for reverence for the past; it may be rooted in tribal and family solidarity or in the endeavour of the privileged classes to base their privileges on heredity. However that may be, the feeling that what is old must be better is still so strong that art historians and archaeologists do not shrink even from historical falsification when attempting to prove that the style of art which appeals to them most is also the oldest.
