The metopes of the Parthenon, originally ninety-two in number, consist of separate panels, almost square, adorned with figures in the highest possible relief, often quite free from the back wall. Each one represents a single combat, Gods against Giants, Lapithæ against Centaurs, Greeks against Amazons, Greeks against Trojans, on the various sides. These subjects, with the contests of Theseus and the labours of Heracles, are the regular themes of sculpture on Greek temples. They all represented to the Greek mind the everlasting moral contest between Hellenism and Barbarism, or between culture and savagery. Heracles destroying monsters like the Hydra snake, Theseus slaying robbers and oppressors of mankind, are symbolical of the conflict between light and darkness. They also, no doubt, bear historical reference to the Persian wars. The best of these metope sculptures are high upon the walls of the Elgin Room. They were the work of subordinate artists, and they vary greatly in excellence. In some we can see the handiwork of old sculptors trained in the archaic school of athletic sculpture, still making their drapery stiff and mechanical. In the best there is great vigour and fine drawing. All are remarkable for the ingenuity of the composition. It was no easy matter to fill ninety-two square panels with struggling figures without monotony or iteration. Nevertheless, I do not think that the Greek artists ever took much pleasure in their metope work. Lastly, we come to the frieze. To judge it rightly, the spectator must remember its position on the temple, for its character is entirely changed when it is seen at the level of the eyes on the walls of our Museum. It ran round the top of the cella wall, 39 feet above the floor, inside the colonnade of the Parthenon. It could be examined by mounting the stylobate and craning your neck uncomfortably, but in an ordinary case you would merely catch glimpses of it between the columns as you passed along outside. Moreover, it was in the shadow of the roof, lighted, as Professor Gardner reminds us, from below by reflection from the white marble pavement. This the artist has foreseen and provided for by making the relief of the upper part deeper than below, so that the heads lean forward from the panels. Where deep shadows are required below they are often secured by cutting into the background. Here is another proof of the advantage Art gains when her ministers are practical craftsmen rather than luxurious gentlemen who spend their time between the studio and the drawing-room. The designer of this frieze--and surely the _designer_ was no less than the master himself--had a free hand here, with no laws of tradition to bind him, for such a frieze is without previous example. He had to cover an uninterrupted space of 524 feet with ornament. He chose for his subject the great procession representing the people of Athens which went up every year at the Panathenaic festival to offer a new saffron robe to
