covering of red damask. The current damask covering, a replica by Scalamandré, is a copy of a pattern that was displayed at Rome's Chigi Palace. The coffered ceiling was reportedly purchased in Italian cardinal's palace. The artist James Wall Finn painted coats-of-arms onto the ceiling based on Italian bookplates from Morgan's collection. Finn's work was designed in such an authentic manner that it was frequently mistaken as part of the ceiling's original design. 231 Madison Avenue Also part of the library grounds is 231 Madison Avenue, an Italianate brownstone house on the southeast corner of Madison Avenue and East 37th Street, which was the home of Isaac Newton Phelps and later J. P. "Jack" Morgan Jr. The house contains the Morgan Shop on its northern side, facing 37th Street, and the Morgan Dining Room on its southern side. The house is set behind a barricade composed of a wrought-iron fence atop a brownstone ledge. The house was originally three stories tall and faced with pink stone, but after R. H. Robertson's renovation of 1888, became four stories tall with a raised basement. An office annex to the east, built in 1957, was originally faced with brick. Before the Morgan acquired it in 1988, it was a headquarters of the Lutheran Church. The Madison Avenue facade consists of three vertical bays.

The second and third stories each have three rectangular, multi-pane windows with sills atop console brackets. A cornice runs above the third story. The attic contains small Ionic colonettes, as well as rounded pediments atop two of the bays. Along 37th Street, the water table containing the raised basement is topped by a molding.

The original section of the house is three bays wide and contains window articulation similar to that of the Madison Avenue facade. On the first floor, the second opening from west has a balcony with an iron balustrade and a pediment supported by
