So it is true that the first picture--whether drawn by the imagination alone in the constellations, on the walls of the cave with ochre and similar materials, or engraved with keen splinters of flint on the mammoth's tusk--the first picture was of the chase. Animals are earliest, the human form next, flowers and designs and stories in drawings next, and landscape last of all. Landscape is peculiarly the art of the moderns--it is the art of _our_ civilisation; no other civilisation seems to have cared for it. Towers and castles are indeed seen on the bas-reliefs of Assyria, and waving lines indicate rivers, but these are merely subsidiary, and to give place and locality to the victories the king is achieving. The battle is the interest, the landscape merely the stage. Till the latter days of European life the artist took no notice of landscape. The painting of hills and rocks and rivers, woods and fields, is of recent date, and even in these scenes the artist finds it necessary to place some animals or birds. Even now he cannot ignore the strong love of human beings for these creatures; if they are omitted the picture loses its interest to the majority of eyes. Every one knows how wonderfully popular the works of Landseer have been, and he was an animal painter, and his subjects chiefly suggested by sport. The same spirit that inspired the Cave-dweller to engrave the mammoth on the slab of ivory still lives in the hearts of men. There is a beautiful etching of "The Poacher" (to which I shall have to recur); he is in the wood, and his dog is watching his upraised finger. From that finger the dog learns everything. He knows by its motion when to start, which way to go, what to do, whether to be quick or slow, to return or to remain away. He understands his master quite as well as if they conversed in human speech. He enters into the spirit of the enterprise. 'If you want your business done, go; if not, send' is true only of men. The poacher wants his business done, and he sends his agent--his dog--certain that it will be done for him better than he could do it himself. The dog is conscientious, he will omit nothing, he will act as if his master's eye was on him the whole time. Now this attitude of the dog's mind is so exquisitely rendered in the picture that he seems verily to speak with intelligence. I love that dog though he does but exist in ink; he is the true image of a real dog, and his mind shines through his body. This effect upon me as the spectator is produced by a clever arrangement of lines upon the plate from which the etching was printed, thin lines cut into the copper with curious sharp tools, behind a screen of tissue-paper to shield the eyes from the light, done in the calm of the studio, thoughtfully, with artistic skill. Given the original genius to conceive such a dog, the knowledge how to express the ideas, and the tools to work with, and we see how it became possible to execute the etching.
