In the matter of colour also the endeavours of Romanticists of the nineteenth century reach a climax in Boecklin. When Schwind and his comrades set themselves to represent the romantic world of fairyland an interdict was still laid upon colour, and it was lightly washed over the drawing, which counted as the thing of prime importance. But Boecklin was the first Romanticist in Germany to reveal the marvellous power in colour for rendering moods of feeling and its inner depth of musical sentiment. Even in those years when the brown tone of the galleries prevailed everywhere, colour was allowed in his pictures to have its own independent existence, apart from its office of being a merely subordinate characteristic of form. For him green was thoroughly green, blue was divinely blue, and red was jubilantly red. At the very time when Richard Wagner lured the colours of sound from music, with a glow and light such as no master had kindled before, Boecklin's symphonies of colour streamed forth like a crashing orchestra. The whole scale, from the most sombre depth to the most chromatic light, was at his command. In his pictures of spring the colour laughs, rejoices, and exults. In "The Isle of the Dead" it seems as though a veil of crape were spread over the sea, the sky, and the trees. And since that time Boecklin has grown even greater. His splendid sea-green, his transparent blue sky, his sunset flush tinged with violet haze, his yellow-brown rocks, his gleaming red sea-mosses, and the white bodies of his girls are always arranged in new glowing, sensuous harmonies. Many of his pictures have such an ensnaring brilliancy that the eye is never weary of feasting upon their floating splendour. A master who died in Rome some nineteen years ago might have been in the province of mural painting for German art what Puvis de Chavannes has become for French. In the earlier histories of art his name is not mentioned. Seldom alluded to in life, dead as a German painter ten years before his death, he was summoned from the grave by the enthusiasm of a friend who was a refined connoisseur four years after the earth had closed over him. Such was _Hans von Marées'_ destiny as an artist. [Illustration: BOECKLIN. VENUS DESPATCHING CUPID.]
