In all the sculpture Calder strove to keep in mind the significance of the Exposition and the spirit of the people who were celebrating. With him styles of architecture and schools were a minor consideration, to be left to the academicians and the critics. He believed that sculpture, like all other art-forms, was chiefly valuable and interesting as human expression. The Decorative Figures Less successful on the whole than the blending of sculpture and architecture were the individual figures designed to be placed against the walls. Some of them were extremely well done. Others were obvious disappointments. The unsophisticated judgment, free from Continental bias, might have objected to the almost gratuitous use of nudity. For a popular exhibition, even the widely-traveled and broad-minded art lover might have been persuaded that a concession to prejudice could have been made without any great damage to art. In the magnificent entrance to the grounds it was deemed fitting that the meaning of the Exposition should be symbolized by an elaborate fountain. So in the heart of the South Gardens there was placed the Fountain of Energy, the design of A. Stirling Calder, the athletic figure of a youth, mounted on a fiery horse, tearing across the globe, which served for pedestal, the symbolic figures of Valor and Fame accompanying on either side. The work, as a whole suggested the triumph of man in overcoming the difficulties in the way, of uniting the two oceans. It made one of the most striking of all the many fountains on the grounds, the dolphins in the great basin, some of them carrying female figures on their backs, contributing to an effect peculiarly French. The Column of Progress The Column of Progress, suggested by Calder and planned in outline by Symmes Richardson, besides being beautiful symbol and remarkably successful in outline, was perhaps the most poetic and original of all the achievements of the sculptors here. It represented something new in being the first great column erected to express a purely imaginative and idealistic conception. Most columns of its kind had celebrated some great figure or historic feat, usually related to war. But this column stood for those sturdy virtues that were developed, not through the hazards and the excitements and the fevers of conquest, but through the persistent and homely tests of peace, through the cultivation of those qualities that laid the foundations of civilized living. Isidore Konti designed the frieze typifying the swarming generations, by Matthew Arnold called "the teeming millions of men," and to Hermon A. MacNeil fell the task of developing the circular frieze of toilers, sustaining the group at the top, three strong figures, the dominating male, ready to shoot his arrow straight alit to its mark, a male supporter, and the devoted woman, eager to follow in the path of advance.
