Horses, which Leonardo, Rubens, Velasquez, Wouwerman, and the earlier English artists delighted to render, he painted but seldom, and when he painted them it was with a less penetrating comprehension. But lions, which had been represented in savage passion or in quiet dignity by artists from Rubens to Decamps, were for him also a subject of long and exhaustive studies, which had their results in the four colossal lions round the base of the Nelson Column in Trafalgar Square. Here the Englishman makes a great advance on Thorwaldsen, who designed the model for the monument in Lucerne without ever having seen a lion. Landseer's brutes, both as they are painted and as they are cast in bronze, are genuine lions, cruel and catlike, although in savageness and bold passion they are not to be compared with those of Delacroix, nor with those of his elder compatriot, James Ward. On the other hand, stags and roes were really first introduced into painting by Landseer. Those of Robert Hills, who had previously been reckoned the best painter of stags, are timid, suspicious creatures, while Landseer's are the true kings of the forest, the shooting of which ought to be punished as an act of assassination. His principal field of study was the Highlands. Here he painted these proud creatures fighting on the mountain slopes, swimming the lake, or as they stand at a gaze in their quiet beauty. With what a bold spirit they raise their heads to snuff the mountain air, whilst their antlers show their delight in battle and the joy of victory. And how gentle and timid is the noble, defenceless roe in Landseer's pictures. [Illustration: LANDSEER. HIGH LIFE.] He had also a delight in painting sheep lost in a snow-storm. But dogs were his peculiar specialty. Landseer discovered the dog. That of Snyders was a treacherous, snarling cur; that of Bewick a robber and a thief. Landseer has made the dog the companion of man, an adjunct of human society, the generous friend and true comrade who is the last mourner at the shepherd's grave. Landseer first studied his noble countenance and his thoughtful eyes, and in doing so he opened a new province to art, in which Briton Rivière went further at a later period.
