Book Description
In this book, Liz James offers a comprehensive history of wall mosaics produced in the European and Islamic middle ages. Taking into account a wide range of issues, including style and iconography, technique and material, and function and patronage, she examines mosaics within their historical context. She asks why the mosaic was such a popular medium and considers how mosaics work as historical 'documents' that tell us about attitudes and beliefs in the medieval world. The book is divided into two part. Part I explores the technical aspects of mosaics, including glass production, labour and materials, and costs. In Part II, James provides a chronological history of mosaics, charting the low and high points of mosaic art up until its abrupt end in the late middle ages. Written in a clear and engaging style, her book will serve as an essential resource for scholars and students of medieval mosaics.

Book Description
New York Times Bestseller Finalist for the Los Angeles Times Book Prize A Library Journal Best Science and Technology Book of the Year An exhilarating exploration of the science and wonder of global bird migration. In the past two decades, our understanding of the navigational and physiological feats that enable birds to cross immense oceans, fly above the highest mountains, or remain in unbroken flight for months at a stretch has exploded. What we’ve learned of these key migrations—how billions of birds circumnavigate the globe, flying tens of thousands of miles between hemispheres on an annual basis—is nothing short of extraordinary. Bird migration entails almost unfathomable endurance, like a sparrow-sized sandpiper that will fly nonstop from Canada to Venezuela—the equivalent of running 126 consecutive marathons without food, water, or rest—avoiding dehydration by "drinking" moisture from its own muscles and organs, while orienting itself using the earth’s magnetic field through a form of quantum entanglement that made Einstein queasy. Crossing the Pacific Ocean in nine days of nonstop flight, as some birds do, leaves little time for sleep, but migrants can put half their brains to sleep for a few seconds at a time, alternating sides—and their reaction time actually improves. These and other revelations convey both the wonder of bird migration and its global sweep, from the mudflats of the Yellow Sea in China to the remote mountains of northeastern India to the dusty hills of southern Cyprus. This breathtaking work of nature writing from Pulitzer Prize finalist Scott Weidensaul also introduces readers to those scientists, researchers, and bird lovers trying to preserve global migratory patterns in the face of climate change and other environmental challenges. Drawing on his own extensive fieldwork, in A World on the Wing Weidensaul unveils with dazzling prose the miracle of nature taking place over our heads.
