The age of the Baroque—a time when great strides were made in science and mathematics—witnessed the construction of some of the world's most magnificent buildings. What did the work of great architects such as Bernini, Blondel, Guarini, and Wren have to do with Descartes, Galileo, Kepler, Desargues, and Newton? Here, George Hersey explores the ways in which Baroque architecture, with its dramatic shapes and playful experimentation with classical forms, reflects the scientific thinking of the time. He introduces us to a concept of geometry that encompassed much more than the science we know today, one that included geometrics (number and shape games), as well as the art of geomancy, or magic and prophecy using shapes and numbers.

Hersey first concentrates on specific problems in geometry and architectural design. He then explores the affinities between musical chords and several types of architectural form. He turns to advances in optics, such as artificial lenses and magic lanterns, to show how architects incorporated light, a heavenly emanation, into their impressive domes. With ample illustrations and lucid, witty language, Hersey shows how abstract ideas were transformed into visual, tactile form—the epicycles of the cosmos, the sexual mystique surrounding the cube, and the imperfections of heavenly bodies. Some two centuries later, he finds that the geometric principles of the Baroque resonate, often unexpectedly, in the work of architects such as Frank Lloyd Wright and Le Corbusier. A discussion of these surprising links to the past rounds out this brilliant reexamination of some of the long-forgotten beliefs and practices that helped produce some of Europe's greatest masterpieces.

Michelangelo, Raphael, Bramante—together these artists created some of the most glorious treasures of the Vatican, viewed daily by thousands of tourists. But how many visitors understand the way these artworks reflect the passions, dreams, and struggles of the popes who commissioned them? For anyone making an artistic pilgrimage to the High Renaissance splendors of the Vatican, George L. Hersey's book is the ideal guide.

Before starting the tour of individual works, Hersey describes how the treacherously shifting political and religious alliances of sixteenth-century Italy, France, and Spain played themselves out in the Eternal City. He offers vivid accounts of the lives and personalities of four popes, each a great patron of art and architecture: Julius II, Leo X, Clement VII, and Paul III. He also tells of the complicated rebuilding and expanding of St. Peter's, a project in which Bramante, Raphael, and Michelangelo all took part.

Having set the historical scene, Hersey then explores the Vatican's magnificent Renaissance art and architecture. In separate chapters, organized spatially, he leads the reader through the Cortile del Belvedere and Vatican Museums, with their impressive holdings of statuary and paintings; the richly decorated Stanze and Logge of Raphael; and Michelangelo's Last Judgment and newly cleaned Sistine Chapel ceiling. A fascinating final chapter entitled "The Tragedy of the Tomb" recounts the vicissitudes of Michelangelo's projected funeral monument to Julius II.

Hersey is never content to simply identify the subject of a painting or sculpture. He gives us the story behind the works, telling us what their particular themes signified at the time for the artist, the papacy, and the Church. He also indicates how the art was received by contemporaries and viewed by later generations.

Generously illustrated and complete with a useful chronology, High Renaissance Art in St. Peter's and the Vatican is a valuable reference for any traveler to Rome or lover of Italian art who has yearned for a single-volume work more informative and stimulating than ordinary guidebooks. At the same time, Hersey's many anecdotes and intriguing comparisons with works outside the Vatican will provide new insights even for specialists.
