The current exhibit at the National Museum of Women in the Arts is, as described in a weekend Baltimore Sun feature, certainly sounds like an "embarrassment of riches," featuring works by Michelangelo, Durer, Botticelli and Titian. Some of the art has never been in an American exhibit before. As the museum's website notes:

Picturing Mary: Woman, Mother, Idea explores the concept of womanhood represented by the Virgin Mary as well as the social and sacred functions her image has served through time. This landmark exhibition organized by the National Museum of Women in the Arts brings together more than 60 Renaissance- and Baroque-era masterworks from the Vatican Museums, Uffizi Gallery, and other museums, churches, and private collections in Europe and the United States.

Divided into six thematic sections, the exhibition presents images of Mary as a daughter, cousin, and wife; the mother of an infant; a bereaved parent; the protagonist in a rich life story developed through the centuries; a link between heaven and earth; and an active participant in the lives of those who revere her.
