Book excerpt: This book features 107 of the finest examples of illuminated pages from medieval and Renaissance Books of Hours. Roger Wieck's comprehensive text introduces the Book of Hours -- a "bestseller" for three hundred years -- to the general reader, discussing its iconography, the artists who illuminated this genre, and its role as a religious text in the lives of its owners. As a collection of both stirring words and inspiring images, the Book of Hours thus comprised a series of "painted prayers".
