Studies of seals and sealing practices have traditionally investigated aspects of social, political, economic, and ideological systems in ancient societies throughout the Old World. Previously, scholarship has focused on description and documentation, chronology and dynastic histories, administrative function, iconography, and style. More recent studies have emphasized context, production and use, and increasingly, identity, gender, and the social lives of seals, their users, and the artisans who produced them. Using several methodological and theoretical perspectives, this volume presents up-to-date research on seals that is comparative in scope and focus. The cross-cultural and interdisciplinary approach advances our understanding of the significance of an important class of material culture of the ancient world. The volume will serve as an essential resource for scholars, students, and others interested in glyptic studies, seal production and use, and sealing practices in the Ancient Near East, Egypt, Ancient South Asia and the Aegean during the 4th-2nd Millennia BCE.

The cultural and historical setting of the Near East provides a unique opportunity to study a longer usage of sealing practices in administration and magic, which extends beyond the constraints of a specific time period or region. Comparing ancient practices with more recent ones can offer important insights into the development of sealing practices and provide answers to specific questions related to the handling of seals and the social status of the seal bearer. Since the initiative towards the workshop was taken by staff members of the NVIC, the focus was on Egypt but other cultures in the Near East and Central Asia were also considered. Following up on the workshop, the present volume retains the geographical and chronological scope, but added a few contributions dealing with the Greco-Roman and Byzantine periods. Glancing at the content, the reader will be struck by the diachronic and spatial persistence of the use of seals for administrative and other purposes, and by their multi-functionality.

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. Contributors are Adrian Ailes, Elka Cwiertnia, Paul Dryburgh, Emir O. Filipovi, Oliver Harris, Philippa Hoskin, Ashley Jones, Andreas Lehnertz, John McEwan, Elizabeth A. New, Jonathan Shea, Caroline Simonet, Angelina A. Volkoff, and Marek L. Wójcik.

A COMPANION TO THE ACHAEMENID PERSIAN EMPIRE A comprehensive review of the political, cultural, social, economic and religious history of the Achaemenid Empirem Often called the first world empire, the Achaemenid Empire is rooted in older Near Eastern traditions. A Companion to the Achaemenid Persian Empire offers a perspective in which the history of the empire is embedded in the preceding and subsequent epochs. In this way, the traditions that shaped the Achaemenid Empire become as visible as the powerful impact it had on further historical development. But the work does not only break new ground in this respect, but also in the fact that, in addition to written testimonies of all kinds, it also considers material tradition as an equal factor in historical reconstruction. This comprehensive two-volume set features contributions by internationally-recognized experts that offer balanced coverage of the whole of the empire from Anatolia and Egypt across western Asia to northern India and Central Asia. Comprehensive in scope, the Companion provides readers with a panoramic view of the diversity, richness, and complexity of the Achaemenid Empire, dealing with all the many aspects of history, event history, administration, economy, society, communication, art, science and religion, illustrating the multifaceted nature of the first true empire. A unique historical account presented in its multiregional dimensions, this important resource deals with many aspects of history, administration, economy, society, communication, art, science and religion it deals with topics that have only recently attracted interest such as court life, leisure activities, gender roles, and more examines a variety of available sources to consider those predecessors who influenced Achaemenid structure, ideology, and self-expression contains the study of Nachleben and the history of perception up to the present day offers a spectrum of opinions in disputed fields of research, such as the interpretation of the imagery of Achaemenid art, or questions of religion includes extensive bibliographies in each chapter for use as starting points for further research devotes special interest to the east of the empire, which is often neglected in comparison to the western territories Part of the acclaimed Blackwell Companions to the Ancient World series, A Companion to the Achaemenid Persian Empire is an indispensable work for students, instructors, and scholars of Persian and ancient world history, particularly the First Persian Empire.

This volume explores how the use of seals enabled long-distance communication, commerce, and interconnectivity in the medieval world.

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.
