Now these facts seem to me to harmonise with the small development of a sense of the picturesque in landscape, which is characteristic of the Greeks. The principles of reproducing perspective with lines and colours on a flat surface were indeed discovered in the fifth century B.C., by a certain Agatharchus, whose book on shade painting seems, however, to have been a work on scene-painting, as an aid to producing illusions on the stage. Nor does the idea of representing external nature seem to have been a want felt by Greek artists, seeing that they had adopted the very peculiar device of representing mountains and rivers by figures of the gods and nymphs which inhabited them and in which they were personified. The heads of the horses rising from the sea represented on the Parthenon the advent of the day. The graceful figures of nymphs on the pediments of the great temple at Olympia represented the scenery in which the action was laid. Looking down the whole history of Greek painting, from the rude frescoes at Tiryns to the decorations of houses at Pompeii, I cannot find that landscape as such ever occupied Greek artists, and here therefore we have one of the very few departments in which the modern world may boast itself independent of its almost universal teacher. It is not so in the case of portrait-painting, and painting of scenes in mythical or in real life, for here even the faint echoes of Greek genius affected powerfully the artists of the Renaissance. In this field, however, the influence of Hellenistic sculpture and of relief work was so combined with that of the few specimens of actual painting from Herculaneum, Pompeii, and other sites, that the separate effect of Greek painting on the modern artists is not so easily appreciated. The mythical subjects at all events were told and glorified in countless epigrams of the Anthology, and as soon as this collection became known and popular, it was sure to dominate the fancy of sentimental artists like Botticelli. But if the direct influence of Greek on modern painting was baulked for want of models, the indirect effect of Greek art on the best of modern painters is very great. Consider for a moment the two most refined of modern English painters, the late Lord Leighton, and the still living and working Sir Edward Alma-Tadema. The latter generally calls his subjects Roman, but anyone that knows what the elegances of Roman life owe to the Greeks, sees at once that the whole spirit of the artist, and of the subjects he delights in, is Greek. The case is still more undisguised with Leighton. All his most striking pictures are from Greek life or from Greek legend; his whole conception of beauty is derived from the same models, and I well remember, when I used to visit him in his delightful studio in Kensington, seeing it all set round with copies of Greek sculpture, and his fervid utterance that to these unapproachable models he owed all his art.
