The artist is impelled to embody concretely his perception of beauty, and so to communicate his emotion, because the emotion wakened by the perception of new harmony in things is most fully possessed and enjoyed as it comes to expression. Thus to make real his ideal and find the expression of himself is the artist's supreme Happiness. A familiar illustration of the twin need and delight of expression may be found in the handiwork produced in the old days when every artisan was an artist. It may be, perhaps, a key which some craftsman of Nuremberg fashioned. In the making of it he was not content to stop with the key which would unlock the door or the chest It was his key, the work of his hands; and he wrought upon it lovingly, devotedly, and made it beautiful, finding in his work the expression of his thought or feeling; it was the realization for that moment of his ideal. His sense of pleasure in the making of it prompted the care he bestowed upon it; his delight was in creation, in rendering actual a new beau which it was given him to conceive. In its origin as a work of art the key does not differ from a landscape by Inness, an "arrangement" by Whistler, a portrait by Sargent. The artist, whether craftsman or painter, is deeply stirred by some passage in his experience, a fair object or a true thought: it is the imperious demand of his nature, as it is his supreme pleasure, to give his feeling expression. The form which his expression takes--it may be key or carpet, it may be statue, picture, poem, symphony, or cathedral--is that which most closely responds to his idea, the form which most truly manifests and represents it. All art, as the expression of the artist's idea, is in a certain definite sense representative. Not that all art reproduces an external reality, as it is said that painting or literature represents and music does not; but every work of art, in painting, poetry, music, or in the handiwork of the craftsman, _represents_ in that it is the symbol of the creator's ideal. To be sure, the painter or sculptor or dramatist draws his symbols from already existing material forms, and these symbols are like objects in a sense in which music is not But line and color and the life of man, apart from this resemblance to external reality, are representative or symbolic of the artist's idea precisely as the craftsman's key, the designer's pattern, or the musician's symphony. The beautifully wrought key, the geometric pattern of oriental rug or hanging, the embroidered foliation on priestly vestment, are works of art equally with the landscape, the statue, the drama, or the symphony, in that they are one and all the sensuous manifestation of some new beauty spiritually conceived.
