Rare medieval manuscript illuminations, last exhibited in 1975, will be showcased in a stunning installation, 'Heaven on Earth: Manuscript Illuminations from the National Gallery of Art,' on view in the East Building from March 1 through August 16, 2009. Fifty-two single leaves and four bound volumes, among them a number of important recent acquisitions, date from the 12th to the 16th century and were made in France, Germany, Austria, Bohemia, the Netherlands, Spain, and Italy. Comprehensive wall texts will include new scholarly information, uncovered since the last time these works were exhibited.
