Before turning to the more important south facade, it is well to look at the east wall, with its dignified and colorful portal. This is Roman in style of architecture, to harmonize with the Palace of Machinery opposite. It is similar in general form to the memorial arches and gateways of the Romans, but in the use of architectural motives and in decoration it is of Italian Renaissance style. The niches at each end of the gallery contain figures of The Miner, by Albert Weinert. The facade is ornamented with buttresses at regular intervals, carrying figures of the California Bear holding a scutcheon with the state seal. Returning to the Avenue of Palms and the south facade, one sees the most important artistic feature of the building, the central portal. This is a copy, except for the figures filling the niches, of the famous doorway of the Hospital of Santa Cruz at Toledo, Spain. It is in Spanish Renaissance style, of that especially rich type known as "Plateresque," due to its likeness to the work of the silversmiths of the time. For its grace of composition, its exquisite detail, its total effect of richness and depth, this portal is worthy of long study. The sculpture of the portal is all by Ralph Stackpole. In the lower niches are replicas of "The Man with a Pick," a figure that has been justly admired as a sincere portrayal of a simple laboring type. The relief panel in the tympanum represents various types of industry. From left to right the figures typify Spinning, Building, and Agriculture (or the clothing, sheltering and feeding of mankind), and Manual Labor, and Commerce. The group in the niche above the arch shows a young laborer taking the load from the shoulders of an old man. The single figure at the top of the arch shows the laborer thinking, and is called "Power." Note how all these sculptures, while having individual interest, fit unobtrusively into the lace-like portal. Palace of Manufactures The wall of this building is broken by pilasters and inset decorative panels, and by a series of niches with animal head fountains. The central portal is pure Renaissance architecture, again suggestive of the Roman gateway in form. The sculptures of the doorway, including the two figures of male and female labor in the niches, and the long high-relief panel, are by Mahonri Young, who is noted for his simple, powerful treatment of modern themes. The panel represents various branches of manufacture, including metal work, blacksmithing, pottery-making, spinning, and architectural sculpture. Palace of Liberal Arts The facade here exactly duplicates that just described, even to the niche figures and panel in the portal. Palace of Education
