VIRTUAL VISITS: Christmas at the Metropolitan Museum of Art. Every year, in continuation of a longstanding holiday tradition, the Met installs in the Medieval Hall its Christmas display, which includes a towering spruce illuminated with glowing lights and decorated with fifty silk-robed angels, and a vivid Nativity scene embellished with life-like figurines. The origins of such elaborate and theatrical crèche displays began in Naples in the 18th century. In the Museum, the tradition of displaying a Christmas tree and crèche began in December 1957 with the exhibition of the 18th century Neapolitan collection of Loretta Hines Howard. By 1964, Mrs. Howard had given to the Museum more than 200 figures. Join Ines Powell for a seated tour of these splendid exhibits. 11 a.m.
