richly decorated, with a polychrome rotunda. It leads to three public rooms: Morgan's private study to the west, the librarian's office to the north, and the original library to the east. The rotunda has a ceiling with murals and plasterwork inspired by Raphael, created by H. Siddons Mowbray. This ceiling contains themed murals in the lunette panels, which allude to material in Morgan's collection, as well as a central dome, which contains roundels and rectangular panels with various figures or motifs. The rotunda floors are clad with multicolored marble, the pattern of which is based on the floor of the Villa Pia in Vatican City. The walls contain mosaic baseboards and are separated into panels with vertical pilasters, topped by Composite style pilasters. The doorways to the rooms on the east and west are made of white marble, topped by marble entablatures and flanked by green marble columns. The interior was designed with two rooms for exhibition. The East Library features triple-tiered bookcases, the upper tiers of which could only be accessed by balconies. On the east wall of the East Library is a fireplace with a tapestry showing the "Triumph of Avarice". The fireplace itself had been imported from Italy. Mowbray designed eighteen lunettes and spandrels atop each wall, modeled after the work of Pinturicchio. The figures in the lunettes alternate between allegorical female muses and notable artists, explorers, or teachers. Zodiac symbols are placed on the spandrels, as the signs of the zodiac were particularly important to J. P. Morgan. Particularly prominent are the zodiac signs over the entrance: Aries corresponds to J. P. Morgan's birth on April 17, 1837, and Gemini corresponds to his marriage to Frances Louisa Tracy on May 31, 1865. Two additional spandrels contain allegorical motifs that depict changing seasons. The East Library had three levels of shelves and is the largest room in the main library wing. Morgan's study, now the West Library, was described by historian Wayne Andrews as "one of the greatest achievements of American interior decoration". The design of the study reflected Morgan's tastes; as his son-in-law Herbert Satterlee said, "No one could really know Mr. Morgan at all unless he had seen him in the West Room." The West Library contains low wooden bookshelves as well as a fireplace with a marble mantelpiece. The decorative elements include stained glass panels in the study's windows, as well as a wall
