Those strange, wild-eyed sibyls fixed eternally in the whirlwind of ecstasy, those mighty-limbed and Titan prophets, labouring with the secret of the earth and the burden of mystery, that guard and glorify the chapel of Pope Sixtus at Rome—do they not tell us more of the real spirit of the Italian Renaissance, of the dream of Savonarola and of the sin of Borgia, than all the brawling boors and cooking women of Dutch art can teach us of the real spirit of the history of Holland? And so in our own day, also, the two most vital tendencies of the nineteenth century—the democratic and pantheistic tendency and the tendency to value life for the sake of art—found their most complete and perfect utterance in the poetry of Shelley and Keats who, to the blind eyes of their own time, seemed to be as wanderers in the wilderness, preachers of vague or unreal things. And I remember once, in talking to Mr. Burne-Jones about modern science, his saying to me, ‘the more materialistic science becomes, the more angels shall I paint: their wings are my protest in favour of the immortality of the soul.’ But these are the intellectual speculations that underlie art. Where in the arts themselves are we to find that breadth of human sympathy which is the condition of all noble work; where in the arts are we to look for what Mazzini would call the social ideas as opposed to the merely personal ideas? By virtue of what claim do I demand for the artist the love and loyalty of the men and women of the world? I think I can answer that. Whatever spiritual message an artist brings to his aid is a matter for his own soul. He may bring judgment like Michael Angelo or peace like Angelico; he may come with mourning like the great Athenian or with mirth like the singer of Sicily; nor is it for us to do aught but accept his teaching, knowing that we cannot smite the bitter lips of Leopardi into laughter or burden with our discontent Goethe’s serene calm. But for warrant of its truth such message must have the flame of eloquence in the lips that speak it, splendour and glory in the vision that is its witness, being justified by one thing only—the flawless beauty and perfect form of its expression: this indeed being the social idea, being the meaning of joy in art. Not laughter where none should laugh, nor the calling of peace where there is no peace; not in painting the subject ever, but the pictorial charm only, the wonder of its colour, the satisfying beauty of its design. You have most of you seen, probably, that great masterpiece of Rubens which hangs in the gallery of Brussels, that swift and wonderful pageant of horse and rider arrested in its most exquisite and fiery moment when the winds are caught in crimson banner and the air lit by the gleam of armour and the flash of plume. Well, that is joy in art, though that golden hillside be trodden by the wounded feet of Christ and it is for the death of the Son of Man that that gorgeous cavalcade is passing.
