McKim, Mead and White of New York, the architects, had the Piazza of St. Peter's at Rome in mind when they designed this great sweep of colonnades. There, too, they borrowed from the circle of saints the idea of the repeated Star figure. The colonnade not only encloses the court but is produced along the sides of the Palaces of Agriculture and Transportation to form two corridors of almost Egyptian vastness. These two features, the arches and the colonnades, here at the center of the palace group, strike the Exposition's note of breadth. Their decoration is the key to the festal richness of all the adornment.

By day the four entrances to the court are its finest features. Nowhere in the whole Exposition is the air more gloriously free than around the lofty arch and colonnades of the Tower of Jewels. Nowhere is the sunlight purer, or the sky bluer, than over the broad approach leading up from the glancing waters of the bay, past the aspiring Column of Progress, and between the noble colonnades of the palaces on either hand. From within the court, or from the approaches on east and west, the triumphal Arches of the Nations impress one with the magnificence of their proportions, their decoration, and their color. There the Oriental hues of the Exposition are carried upward, to meet and blend with the sky, and magically to make the heavens above them bluer than they really are. (See frontispiece.)

There is little Oriental about the court, except the color and the group of the Nations of the East above the Arch of the Rising Sun. The colonnade is Corinthian, all the arches are Roman, the sculpture is classic, the paintings are romantic, mystic,—the Court of the Universe may properly hold all things. It is thus an arena for the expression of universal themes, on which the nations of the East and West look down from their lofty Arches of Triumph. With this key, the symbolism of the sculpture in the court is easy. The Stars, by Calder, stand in circle above the colonnade. The frieze below the cornices of the pavilion towers represents the Signs of the Zodiac, by Herman A. MacNeil.

The graceful figures atop the two fountain columns in the oval sunken garden are the Rising and the Setting Sun, by Adolph A. Weinmann. (p. 69.) In the east the Sun, in the strength of morning, the masculine spirit of "going forth," has spread his wings for flight; in the west, the luminary, now essentially feminine, as the brooding spirit of evening, is just alighting. The sculptural adornment of the shafts is detailed in the chapter on Fountains.

The titanic Elements slumber on the balustrade, one on either hand of the stairways leading down on north and south into the sunken area. (p. 64.) On one side, on the north, the Elemental Power holds in check the Dragon of Fire. The whole figure expresses the primitive terror of Fire, a fear that still lives in the beasts. On the other side lies Water, the roaring Ocean, kelp in his hair, Neptune's trident in his hand, by him one of his fabled monsters. On the south, eagles of the Air hover close to the winged figure of the woman, who holds up the evening star and breathes gently down upon her people. Icarus, who was the first airman, appears upon her wings. Opposite, rests Earth, unconscious that her sons struggle with her. These remarkably expressive figures are the work of Robert Aitken.

The youthful groups by Paul Manship upon the extremities of the balustrade, on either hand of the eastern and western stairways, represent Music and Poetry, Music by the dance, Poetry by the written scroll. The sculpture is archaic in type,—an imitation of Greek imitations of still earlier models.

The colossal groups on the Arches of the Nations symbolize the meeting of the peoples of the East and West, brought together by the Panama Canal, and here uniting to celebrate its completion. In the group of the Nations of the East the elephant bears the Indian prince, and within the howdah, the Spirit of the East, mystic and hidden. (p. 63.) On the right is the Buddhist lama from Tibet, representative of that third of the human race which finds hope of Nirvana in countless repetitions of the sacred formula, "Om Mani Padme Hum." Next is the Mohammedan, with the crescent of Islam; then a negro slave, and then a Mongolian warrior, the ancient inhabitant of the sandy waste, a type of those Tartar hordes which swept Asia under Tamerlane and Genghis Khan. On the left of the Indian elephant are an Arab falconer, an Egyptian mounted on a camel and bearing a Moslem standard, then a negro slave bearing a basket of fruit on his head, and a sheik from the deserts of Arabia, all representing the Mohammedans of the nearer East. Thus are figured types of the great Oriental races, the Hindoo, the Tartar, which includes the Turk and the northern Chinese; the Chinese stock of the south, the Arab, and the Egyptian. Only the Persian is omitted, and possibly the Japanese, unless that, too, is Mongol.

On the Arch of the Setting Sun, the prairie schooner is the center of the group of the Nations of the West, on the top a figure of Enterprise, the Spirit of the West. (p. 59.) On either side of her is a boy. These are the Heroes of Tomorrow. Between the oxen rides the Mother of Tomorrow. Beside the ox at the right is the Italian immigrant, behind him the Anglo-American, then the squaw with her papoose, and the horse Indian of the plains. By the ox at the left is the Teuton pioneer, behind him the Spanish conquistador, next, the woods Indian of Alaska, and lastly the French Canadian.

Three sculptors collaborated in the modeling of these groups, A.
Stirling Calder, Leo Lentelli, and Frederick G. R. Roth.

Of the Mural Paintings under the Arches of the Nations, the two by Edward Simmons in the arch on the east are an allegory of the movement of the peoples across the Atlantic, while those by Frank Vincent Du Mond in the western arch picture in realistic figures the westward march of civilization to the Pacific. Historically, the picture on the southern wall of the Arch of the Nations of the East comes first. Here Simmons has represented the westward movement from the Old World through natural emigration war, conquest, commerce and religion, personifying these in types of the people who have crossed the Atlantic. On the strand, beyond which appear types of the navies of the ages, are the following: an inhabitant of the fabled Atlantis, here conceived as a savage; the Greek warrior, perhaps one of those who fared with Ulysses over the sea to the west; the adventurer and explorer, portrayed as Columbus; the colonist, Sir Walter Raleigh; the missionary, in garb of a priest; the artist, and the artisan. All are called onward by the trumpet of the Spirit of Adventure, to found new families and new nations, symbolized by the vision of heraldic shields. Behind them stands a veiled figure, the Future listening to the Past. The long period in which this movement has been in progress is expressed by the dress of the travellers.
