The three figures repeated around the top of the arcade are of a hunter dragging a deer, a woman with her offspring on her shoulder, and a primitive man feeding a pelican, all so happily expressed that they are an intimate part of the arcade on which they stand. They seem almost to have grown from their supports. These figures alone, unless we add the florid ladies of the ornamental shafts, with the rich filigree of the arcades and the tower, are all that express in any way the idea of Abundance carried in the present name of the court. Mullgardt conceived this court as a sermon in stone. Its significance as a whole is best explained by the architect himself. He interprets the court as rising in four horizontal strata: "The court is an historical expression of the successive Ages of the world's growth. The central fountain symbolizes the nebulous world, with its innate human passions. Out of a chaotic condition came Water (the basin), and Land (the fountain), and Light (the Sun, supported by Helios, and the electroliers). The braziers and cauldrons symbolize Fire. The two sentinel columns to the right and left of the tower symbolize Earth and Air. The eight paintings of the four corners of the ambulatory symbolize the elements of Earth, Air, Fire and Water. The central figure in the North Avenue symbolizes 'Modern Time Listening to the Story of the Ages.' "The decorative motifs employed on the surrounding arcade are sea-plant life and its animal evolution. The piers, arches, reeds and columns bear legendary decorative motifs of the transition of plant to animal life in the forms of tortoise and other shell motifs;--kelp and its analogy to the prehistoric lobster, skate, crab and sea urchin. The water-bubble motif is carried through all vertical members which symbolize the Crustacean Period, which is the second stratum of the court. "The third stratum, the prehistoric figures, surmounting the piers of the arcade, also the first group over the tower entrance, show earliest forms of human, animal, reptile and bird life, symbolizing the Stone Age Period.
