One of the most serious and thoughtful works of the Exposition sculpture is the Column of Progress which faces the bay at the end of the Forecourt of Stars. This column represents with direct imagery the upward progress of man. The shaft itself is sculptured with conventionalized waves in a gradually ascending spiral, upon which a repeated vessel, the Ship of Life, sails upward, indicating the slow upward rise of our life. The lower panels, significant of man's endeavors, are described on the following page. The crowning group, "The Adventurous Bowman," noble in intent and in sculptural power, is from the hand of Hermon A. MacNeil. At the highest point of man's achievement, stands this Adventurous Bowman, the super-hero, the leader, the man with insight into the future, who shoots his arrow into the Sun of Truth. Behind him the next man supports and is protected, by him. Beside him kneels the woman with his reward in her hands. The frieze beneath the group shows the Burden-Bearers on whose shoulders the hero stands - an arresting thought; reminder of the true values in modern life. Frieze Base, Column of Progress The four panels at the base of the Column of Progress sympathetically express its exalted idealism. They are by Isadore Konti, in richly wrought high relief. The play of color values, the planes of light and shade, are handled with mastery. These four panels indicate that the thought, the dream, the aspiration, the dutiful devotion underlying all the labors of the common day are the source of their progress. One panel shows the higher toils of the mind, as in the arts and statesmanship. In the center of this stands the inventor or leader of thought with the eagle of aspiration above him. Another shows the motives of love and pain and prayer and the central power of labor as movers of the world. Still another, which is shown here, expresses the humbler toils of mankind; even they, it says, progress upward through the thinker who pauses in their midst to dream. The other panel here pictured represents the triumph of man's endeavors, and the successes that spur to greater achievements. Primitive Ages Altar Tower, Court of Ages
