It is true that the Pre-Raphaelites with both brush and pen betray a certain, though by no means exclusive, predilection for the Middle Ages; but the mediævalism of their poems and paintings is not historical, but mythical, and simply denotes something outside time and space--a time of dreams and a place of dreams, where all unreal figures and actions may be conveniently bestowed. That they decorate their unearthly world with some features which may remotely recall mediævalism; that it is peopled with queens and knights, noble damozels with coronets on their golden hair, and pages with plumed caps--these may be accounted for by the prototypes which, perhaps unconsciously, hover before the eyes of the Pre-Raphaelites. Movements in art and literature do not spring up suddenly and spontaneously. They have progenitors from whom they descend in the natural course of generation. Pre-Raphaelitism is the grandson of German, and a son of French, Romanticism. But in its wanderings through the world Romanticism has suffered such alteration through the influence of the changing opinions of the times, and the special characteristics of various nations, that the English offspring bears scarcely any family resemblance to its German ancestor. German romanticism was in its origin a reaction against the spirit of the French encyclopædists, who had held undisputed sway over the eighteenth century. Their criticism of ancient errors, their new systems which were to solve the riddles of the world and of the nature of man, had at first dazzled and nearly intoxicated mankind. They could not, however, satisfy in the long-run, for they committed a great fault in two respects. Their knowledge of facts was insufficient to enable them to explain the collective phenomenon of the universe, and they looked upon man as an intellectual being. Proud of their strictly logical and mathematical reasoning, they overlooked the fact that this is a method of knowledge, but not knowledge itself. The logical apparatus is a machine, which can manufacture only the material shot into it. If the machine is not fed, it runs on empty and makes a noise, but produces nothing. The condition of science in the eighteenth century did not allow the encyclopædists to make advantageous use of their logical machine. They did not take cognizance of this fact, however, and, with their limited material and much unconscious temerity, constructed a system which they complacently announced as a faithful representation of the system of the universe. It was soon discovered that the encyclopædists, for all their intellectual arrogance, were deluding both themselves and their followers. There were known facts which contradicted their hasty explanations, and there was a whole range of phenomena of which their system took no account, and failed to cover as if with too short a cloak, and which peeped out mockingly at all the seams. Hence the philosophy of the encyclopædists
