The use of perspective in Renaissance painting caused a revolution in the history of seeing, allowing artists to depict the world from a spectator's point of view. But the theory of perspective that changed the course of Western art originated elsewhere-it was formulated in Baghdad by the eleventh-century mathematician Ibn al Haithan, known in the West as Alhazen. Using the metaphor of the mutual gaze, or exchanged glances, Hans Belting-preeminent historian and theorist of medieval, Renaissance, and contemporary art-narrates the historical encounter between science and art, between Arab Baghdad and Renaissance Florence, that has had a lasting effect on the culture of the West.

In this lavishly illustrated study, Belting deals with the double history of perspective, as a visual theory based on geometrical abstraction (in the Middle East) and as pictorial theory (in Europe). How could geometrical abstraction be reconceived as a theory for making pictures? During the Middle Ages, Arab mathematics, free from religious discourse, gave rise to a theory of perspective that, later in the West, was transformed into art when European painters adopted the human gaze as their focal point. In the Islamic world, where theology and the visual arts remained closely intertwined, the science of perspective did not become the cornerstone of Islamic art. "Florence and Baghdad" addresses a provocative question that reaches beyond the realm of aesthetics and mathematics: What happens when Muslims and Christians look upon each other and find their way of viewing the world transformed as a result?

The infamous emperor Caligula ruled Rome from A.D. 37 to 41 as a tyrant who ultimately became a monster. An exceptionally smart and cruelly witty man, Caligula made his contemporaries worship him as a god. He drank pearls dissolved in vinegar and ate food covered in gold leaf. He forced men and women of high rank to have sex with him, turned part of his palace into a brothel, and committed incest with his sisters. He wanted to make his horse a consul. Torture and executions were the order of the day. Both modern and ancient interpretations have concluded from this alleged evidence that Caligula was insane. But was he? This biography tells a different story of the well-known emperor. In a deft account written for a general audience, Aloys Winterling opens a new perspective on the man and his times. Basing Caligula on a thorough new assessment of the ancient sources, he sets the emperor's story into the context of the political system and the changing relations between the senate and the emperor during Caligula's time and finds a new rationality explaining his notorious brutality.

Pompeii's tragedy is our windfall: an ancient city fully preserved, its urban design and domestic styles speaking across the ages. This richly illustrated book conducts us through the captured wonders of Pompeii, evoking at every turn the life of the city as it was 2,000 years ago. When Vesuvius erupted in 79 A.D. its lava preserved not only the Pompeii of that time but a palimpsest of the city's history, visible traces of the different societies of Pompeii's past. Paul Zanker, a noted authority on Roman art and architecture, disentangles these tantalizing traces to show us the urban images that marked Pompeii's development from country town to Roman imperial city. Exploring Pompeii's public buildings, its streets and gathering places, we witness the impact of religious changes, the renovation of theaters and expansion of athletic facilities, and the influence of elite families on the city's appearance. Through these stages, Zanker adeptly conjures a sense of the political and social meanings in urban planning and public architecture. The private houses of Pompeii prove equally eloquent, their layout, decor, and architectural detail speaking volumes about the life, taste, and desires of their owners. At home or in public, at work or at ease, these Pompeians and their world come alive in Zanker's masterly rendering. A provocative and original reading of material culture, his work is an incomparable introduction to urban life in antiquity.

This book is a profound reexamination of the role of the German army, the Wehrmacht, in World War II. Until very recently, the standard story avowed that the ordinary German soldier in World War II was a good soldier, distinct from Hitler's rapacious SS troops, and not an accomplice to the massacres of civilians. Wolfram Wette, a preeminent German military historian, explodes the myth of a "clean" Wehrmacht with devastating clarity.

This book reveals the Wehrmacht's long-standing prejudices against Jews, Slavs, and Bolsheviks, beliefs that predated the prophecies of "Mein Kampf" and the paranoia of National Socialism. Though the sixteen-million-member German army is often portrayed as a victim of Nazi mania, we come to see that from 1941 to 1944 these soldiers were thoroughly involved in the horrific cleansing of Russia and Eastern Europe. Wette compellingly documents Germany's long-term preparation of its army for a race war deemed necessary to safeguard the country's future; World War II was merely the fulfillment of these plans, on a previously unimaginable scale.

This sober indictment of millions of German soldiers reaches beyond the Wehrmacht's complicity to examine how German academics and ordinary citizens avoided confronting this difficult truth at war's end. Wette shows how atrocities against Jews and others were concealed and sanitized, and history rewritten. Only recently has the German public undertaken a reevaluation of this respected national institution--a painful but necessary process if we are to truly comprehend how the Holocaust was carried out and how we have come to understand it.
