Generations of scholars have grappled with the origins of 'palace' society on Minoan Crete, seeking to explain when and how life on the island altered monumentally. Emily Anderson turns light on the moment just before the palaces, recognizing it as a remarkably vibrant phase of socio-cultural innovation. Exploring the role of craftspersons, travelers and powerful objects, she argues that social change resulted from creative work that forged connections at new scales and in novel ways. This study focuses on an extraordinary corpus of sealstones which have been excavated across Crete. Fashioned of imported ivory and engraved with images of dashing lions, these distinctive objects linked the identities of their distant owners. Anderson argues that it was the repeated but pioneering actions of such diverse figures, people and objects alike, that dramatically changed the shape of social life in the Aegean at the turn of the second millennium BCE.

For 7,000 years seals have functioned as signs of authority. This publication deals specifically with aspects of status in the history of seals, exploring this theme across a diverse range of cultural contexts--from the 9th century up to the Early Modern period, and, across the world, looking at Byzantine, European, Islamic and Chinese examples. These objects are united by the significant role they play in social status hierarchies, in the status of institutions, indications of power and finally in notions of relative status among objects themselves. In addition to their chronological and geographical diversity, these studies concentrate on many different phases of seal use. Therefore, together they highlight the importance of studying the full life cycle of seals, from the way in which they were made and used through to their cancellation, loss and sometimes destruction. The volume will look at seals used by all members of society, from kings to fishmongers, and will examine the history of objects, with examples ranging from the medieval matrix with a classical gem showing the Roman Emperor Antoninus Pius to the 17th-century Providence Island matrix from America. This publication complements the British Museum's ongoing programme of the digitisation of the Museum's collection of medieval seal matrices which will widen access to this fascinating body of material.

Fur seals and sea lions are charismatic, large carnivores that engage us with both their skill and playful antics. Although all species in Australian waters were harvested to near extinction 200 years ago, fur seals are recovering and are now common in near-shore waters across southern Australia. Sea lions, however, are endangered. Their populations appear not to have recovered like fur seals and are declining at some locations. Fur seals and sea lions are important top level predators and play an important role in Australia’s temperate marine ecosystems. Key threats they currently face relate to human activities, particularly interactions with fisheries. This book outlines the comparative evolutionary ecology, biology, life-history, behaviour, conservation status, threats, history of human interactions and latest research on the three species of otariids that live in the waters of southern Australia: the Australian fur seal, New Zealand fur seal and Australian sea lion. It also includes brief descriptions of Antarctic and Subantarctic seals that occupy the Antarctic pack-ice and remote Australian territories of Macquarie Island and Heard Island.

The largest of all seals, elephant seals rank among the most impressive of marine mammals. They are renowned for their spectacular recovery from near-extinction at the end of the nineteenth century when seal hunters nearly eliminated the entire northern species. No other vertebrate has come so close to extinction and made such a complete recovery. The physiological extremes that elephant seals can tolerate are also remarkable: females fast for a month while lactating, and the largest breeding males fast for over one hundred days during the breeding seasons, at which times both sexes lose forty percent of their body weight. Elephant seals dive constantly during their long foraging migrations, spending more time under water than most whales and diving deeper and longer than any other marine mammal. This first book-length discussion of elephant seals brings together worldwide expertise from scientists who describe and debate recent research, including the history and status of various populations, their life-history tactics, and other findings obtained with the help of modern microcomputer diving instruments attached to free-ranging seals. Essential for all marine mammalogists for its information and its methodological innovations, Elephant Seals will also illuminate current debates about species extinctions and possible means of preventing them.

Describes all seal types used in industry for rotating, oscillating and reciprocating shaft applications. The work details the various practices for radial shaft seal selection, testing and installation recommended by the Society of Automotive Engineers, the Rubber Manufacture's Association, the American Society for Testing and Materials, and the American Society of Tribology and Lubrication Engineers, among others.

A Companion to Seals in the Middle Ages is a cross-disciplinary collection of fourteen essays on medieval sigillography. It is organized thematically, and it emphasizes important, often cutting-edge, methodologies for the study of medieval seals and sealing cultures. As the chronological, temporal and geographic scope of the essays in the volume suggests, the study of the medieval seal—its manufacture, materiality, usage, iconography, inscription, and preservation—is a rich endeavour that demands collaboration across disciplines as well as between scholars working on material from different regions and periods. It is hoped that this collection will make the study of medieval seals more accessible and will stimulate students and scholars to employ and further develop these material and methodological approaches to seals.
