View of the old entrance to the Morgan library, 33 East 36th Street. Built 1903-1906 ; Architect: Charles McKim of McKim, Meade & White. The rotunda connected the building's three main rooms: J.P. Morgan's study, J.P. Morgan's library, and the librarian's office. Visitors now enter through a side door which connects the McKim building to the Renzo Piano atrium. The rotunda's dome rises above the composite capitals of the hall's white marble pilasters and green marble columns. The dome's murals are by Henry Siddons Mowbray who looked to Italian Renaissance prototypes when designing his decorative scheme. Pictured is the lunette on the west wall of the rotunda. Mowbray's mural depicts the muse of Lyrical Poetry flanked by poets Tasso and Petrarch.
