Book Description
Conceived in the 1930s, simplified and successfully tested in the 1950s, the darling of the automotive industry in the early 1970s, then all but abandoned before resurging for a brilliant run as a high-performance powerplant for Mazda, the Wankel rotary engine has long been an object of fascination and more than a little mystery. A remarkably simple design (yet understood by few), it boasts compact size, light weight and nearly vibration-free operation. In the 1960s, German engineer Felix Wankel's invention was beginning to look like a revolution in the making. Though still in need of refinement, it held much promise as a smooth and powerful engine that could fit in smaller spaces than piston engines of similar output. Auto makers lined up for licensing rights to build their own Wankels, and for a time analysts predicted that much of the industry would convert to rotary power. This complete and well-illustrated account traces the full history of the engine and its use in various cars, motorcycles, snowmobiles and other applications. It clearly explains the working of the engine and the technical challenges it presented--the difficulty of designing effective and durable seals, early emissions troubles, high fuel consumption, and others. The work done by several companies to overcome these problems is described in detail, as are the economic and political troubles that nearly killed the rotary in the 1970s, and the prospects for future rotary-powered vehicles.

Book Description
In recent decades, the study of Roman art has shifted focus dramatically from issues of connoisseurship, typology, and chronology to analyses of objects within their contemporary contexts and local environments. Scholars challenge the notion, formerly taken for granted, that extant historical texts—the writings of Vitruvius, for example—can directly inform the study of architectural remains. Roman-era statues, paintings, and mosaics are no longer dismissed as perfunctory replicas of lost Greek or Hellenistic originals; they are worthy of study in their own right. Further, the scope of what constitutes Roman art has expanded to include the vast spectrum of objects used in civic, religious, funerary, and domestic contexts and from communities across the Roman Empire. The work gathered in Roman Artists, Patrons, and Public Consumption displays the breadth and depth of scholarship in the field made possible by these fundamental changes. The first five essays approach individual objects and artistic tropes, as well as their cultural contexts and functions, from fresh and dynamic angles. The latter essays focus on case studies in Pompeii, demonstrating how close visual analysis firmly rooted in local and temporal contexts not only strengthens understanding of ancient interactions with monuments but also sparks a reconsideration of long-held assumptions reinforced by earlier scholarship. These rigorous essays reflect and honor the groundbreaking scholarship of Elaine K. Gazda. In addition to volume editors Brenda Longfellow and Ellen E. Perry, contributors include Bettina Bergmann, Elise Friedland, Barbara Kellum, Diana Y. Ng, Jessica Powers, Melanie Grunow Sobocinski, Lea M. Stirling, Molly Swetnam-Burland, Elizabeth Wolfram Thill, and Jennifer Trimble.
