The Pieta is to be exhibited at the World's Fair in 1964: This may make children eager to read this Credo book, The Wings of an Eagle, and absorbing reading they'll find it. Here Anne Peck paints a vivid picture of the life-long struggles of Michelangelo -- sculptor, painter, architect, engineer and philosopher -- who lived for almost ninety years in the turbulent, colorful times of 16th Century Italy. The story of the carving of the Pieta, an interesting facet of the story and how it happens to be the only work to which Michelangelo set his signature, is especially interesting.
