On this foundation a loftier structure was soon built and the builders were George Inness, Alexander Wyant and Homer D. Martin. Inness was the oldest of the three, having been born in 1825, and was contemporary with some of the most arbitrary and hide-bound of the nature copyists. But he felt the weakness of the method and himself attained a much fuller and completer art. He seems to have dabbled with paint and brushes from his youth, but had little regular instruction, studying, for the most part, from prints of old pictures, and finally, in 1847, getting a chance to see the original when a friend offered to send him to Europe. He passed fifteen months in Rome, and afterwards a year at Paris. A long period of assimilation followed, in which he developed a theory of art and struggled to transfer it to canvas. It was a sound and true theory, and is worth setting down here for its own sake. "The purpose of the painter," Inness held, "is to reproduce in other minds the impression which a scene had made upon him. A work of art does not appeal to the intellect or to the moral sense. Its aim is not to instruct, not to edify, but to awaken an emotion. It must be a single emotion, if the work has unity, as every such work should have, and the true beauty of the work consists in the beauty of the sentiment or emotion which it inspires. Its real greatness consists in the quality and force of this emotion." To the very last, Inness's work was changing and developing to fit this theory. He steadily gained mastery of tone and breadth of handling, of true harmony, and it is his crowning merit that he does to some extent succeed in "reproducing in other minds the impression which the scene made upon him." Alexander H. Wyant was a pupil of Inness, journeying from the little Ohio town where he was born to see him and to ask for advice and aid, which Inness freely gave. Wyant's boyhood had been the American artist's usual one--an early fondness for drawing, a little practice, and then setting up as a painter. In 1873 he joined an expedition to Arizona and New Mexico. The hardships which he endured resulted in a stroke of paralysis and he was never again able to use his right hand. With an inspiring patience, he set to work to learn to use his left hand, and grew to be more skillful with it than he had been with his right. But even at his best, Wyant's appeal is more limited than Inness's. He learned to paint a typical picture, a glimpse of rolling country seen between the trunks of tall and slender birches or maples, and was content to paint variations of it over and over. That he sometimes did it superbly cannot be denied, and he possessed a certain delicate refinement, an ability to throw upon his pictures the silvery shimmer of summer sunshine, in which no other American artist has ever surpassed him.
