Automobiles, interstate highways, shorter work weeks, longer vacations, and higher salaries have all combined to bring the seashore closer to man. Where once a visit to the shore was only a dream for many, or a once-in-a-lifetime trip for others, the varied oceanic life that has held man's interest for centuries is now just beyond the garage doors of the American family. The same curiosity that stirs the beachcombing instincts of coastal dwellers is possessed by inlanders, and now a midwesterner too can do something about that curiosity. A vacation at the shore is much within his grasp as a visit to the nearest state park. Each year more and more inland residents are taking coastal vacations. As a result beachcombing is more popular than ever, with the same old questions being repeated over and over: "What's this?" "Where do you suppose they came from?" Is that a plant or an animal?" Unfortunately, the answers in too many instances are not readily available. This book is written for the layman. It is color-coded and fully illustrated. The casual visitor of the Atlantic Coast of the United States now has an easy to use, illustrated guide for the quick identification of the marine plants along the coast.

In the eighth and ninth centuries, three Byzantine empresses—Irene, Euphrosyne, and Theodora—changed history. Their combined efforts restored the veneration of icons, saving Byzantium from a purely symbolic and decorative art and ensuring its influence for centuries to come. In this exhilarating and highly entertaining account, one of the foremost historians of the medieval period tells the story of how these fascinating women exercised imperial sovereignty with consummate skill and sometimes ruthless tactics. Though they gained access to the all-pervasive authority of the Byzantine ruling dynasty through marriage, all three continued to wear the imperial purple and wield tremendous power as widows. From Constantinople, their own Queen City, the empresses undermined competitors and governed like men. They conducted diplomacy across the known world, negotiating with the likes of Charlemagne, Roman popes, and the great Arab caliph Harun al Rashid. Vehemently rejecting the ban on holy images instituted by their male relatives, Irene and Theodora used craft and power to reverse the official iconoclasm and restore icons to their place of adoration in the Eastern Church. In so doing, they profoundly altered the course of history. The art—and not only the art—of Byzantium, of Islam, and of the West would have been very different without them. As Judith Herrin traces the surviving evidence, she evokes the complex and deeply religious world of Constantinople in the aftermath of Arab conquest. She brings to life its monuments and palaces, its court ceremonies and rituals, the role of eunuchs (the "third sex"), bride shows, and the influence of warring monks and patriarchs. Based on new research and written for a general audience, Women in Purple reshapes our understanding of an empire that lasted a thousand years and splashes fresh light on the relationship of women to power.

An engaging and richly illustrated exploration of the natural history of seaweeds and other algae As photosynthetic organisms, seaweeds and other algae transfer billions of tons of carbon globally from the atmosphere to the deep ocean each year. Coming in all manner of colors, shapes, and sizes, from bioluminescent single-celled algae to giant kelps, they form the basis of most marine food webs, and are found in almost all environments on the planet. Touted as the biofuel of the future, seaweeds and algae also hold promise for biodegradable packaging, offer a nutritious food source, and exhibit antiviral and antitumor properties. Combining accessible text with stunning images and graphics, this book takes a deep dive to explore the unique characteristics of seaweeds and other algae, outlining their extraordinary evolution as well as their morphology, life histories, ecology, and uses. Offering rare insights into the algal world, The Lives of Seaweeds is essential reading for naturalists and marine life enthusiasts.
