He is indeed the only true realist: symbolism, which is the essence of the transcendental spirit, is alien to him. The metaphysical mind of Asia will create for itself the monstrous, many-breasted idol of Ephesus, but to the Greek, pure artist, that work is most instinct with spiritual life which conforms most clearly to the perfect facts of physical life. 'The storm of revolution,' as Andre Chenier said, 'blows out the torch of poetry.' It is not for some little time that the real influence of such a wild cataclysm of things is felt: at first the desire for equality seems to have produced personalities of more giant and Titan stature than the world had ever known before. Men heard the lyre of Byron and the legions of Napoleon; it was a period of measureless passions and of measureless despair; ambition, discontent, were the chords of life and art; the age was an age of revolt: a phase through which the human spirit must pass but one in which it cannot rest. For the aim of culture is not rebellion but peace, the valley perilous where ignorant armies clash by night being no dwelling-place meet for her to whom the gods have assigned the fresh uplands and sunny heights and clear, untroubled air. And soon that desire for perfection, which lay at the base of the Revolution, found in a young English poet its most complete and flawless realisation. Phidias and the achievements of Greek art are foreshadowed in Homer: Dante prefigures for us the passion and colour and intensity of Italian painting: the modern love of landscape dates from Rousseau, and it is in Keats that one discerns the beginning of the artistic renaissance of England. Byron was a rebel and Shelley a dreamer; but in the calmness and clearness of his vision, his perfect self-control, his unerring sense of beauty and his recognition of a separate realm for the imagination, Keats was the pure and serene artist, the forerunner of the pre-Raphaelite school, and so of the great romantic movement of which I am to speak. Blake had indeed, before him, claimed for art a lofty, spiritual mission, and had striven to raise design to the ideal level of poetry and music, but the remoteness of his vision both in painting and poetry and the incompleteness of his technical powers had been adverse to any real influence. It is in Keats that the artistic spirit of this century first found its absolute incarnation. And these pre-Raphaelites, what were they? If you ask nine-tenths of the British public what is the meaning of the word aesthetics, they will tell you it is the French for affectation or the German for a dado; and if you inquire about the pre-Raphaelites you will hear something about an eccentric lot of young men to whom a sort of divine crookedness and holy awkwardness in drawing were the chief objects of art. To know nothing about their great men is one of the necessary elements of English education.
