It was plain enough that the top of the Exposition had not received the praise it deserved. "Think how crude that scene would have been if it had presented a straggling mass of roofs. And even as it is, with its graceful lines, if it were lacking in color it would seem crude. Perhaps it will help us to realize how unsightly most of the roofs of our houses are, and how unfinished. There's no reason in the world why they should be. The Greeks and the Romans had the right idea. They were very sensitive to lack of finish. They felt the charm of decorated roofs. See that angel down there that keeps recurring at the points of the gables. What a pretty bit of ornamentation. The Greeks used it to suggest the gifts of the gods coming down from heaven. 'Blessings on this house.' I suppose the wreath in the hand used here was meant to suggest the crowning of the work. It explains why the figure is called "Victory." By the way, it has an architectural value in giving lightness and grace to the roofs." The builders, we could see, had cleverly adapted their plans to the conditions. "The effect might so easily have been monotonous and cold, and it might have been flat and dreary. It was a fine idea to lift the central portion of each of those main palaces above the surfaces of the roofs to introduce the semicircular windows in the domes. It helped to infuse the scene with a kind of tenderness and spirituality. And see how the two groups on top of the triumphal arches, the Orientals and the Pioneers, contribute to the soaring effect and to the finish at the same time. The Romans disliked bareness on the top of their arches. They wanted life up there, the more animated the better. So they put on some of their most dramatic scenes, like their chariot races."
