A pigeon carrying an important message takes the reader on a unique tour through Rome, a place where the past and the present live side by side. This juxtaposition of the ancient and the modern, as seen with David Macaulay's ingenious vision, gives the reader an imaginative and informative journey through this most wonderful of cities. "Macaulay's latest celebration of architecture delights in showing how past and present coexist in this ancient city. . . . A visual love letter to the city of Rome. A natural choice for classroom use and a terrific way to whet readers' appetites for Macaulay's earlier titles, such as City." --Booklist, boxed review
