Classical Marble Geochemistry Technology Trade

Marble in Ancient Greece and Rome: Geology, Quarries, Commerce, Artifacts Marble remains the sine qua non raw material of the an cient Greeks and Romans. Beginning in the Bronze Age sculptu re began in marble and throughout classical times the most im portant statues, reliefs, monuments and inscriptions were made of it. Yet, quarry sources changed in time as preferences for different marbles were influenced by local traditions, the pos sibilities of transport, esthetic tastes, and economics. Marble studies and the identification of the provenance of marble can thus reveal much about Greek and Roman history, trade, esthe tics and technology. Persons in many disciplines are studying various aspects of Greek and Roman marble usage. Geologists and geochemists are working on methods to determine the provenance of marble; ar chaeologists are noting changing patterns of import and use in excavation~ and discovering how improving quarrying techniques and prelimihary dressing of the extracted material influenced the final shape of artifacts; ancient historians are now under standing quarry organization and bureaucracies that controlled marble production and trade; art historians are seeing how phy sical characteristics of the stone affected the techniques and style of sculpture; architects and engineers are interested in quarry technologies and usage in building construction. These specialists drawn from many disciplines rarely have an opportu nity to compare notes and see how each can contribute to the research effort of others.

The meeting assembled an interdisciplinary group of nearly 50 archaeologists and art historians, geologists and geochemists from the U.S.A. and 14 European and Near Eastern countries to discuss the provenance, quarrying, transport and use of stone from prehistoric to early Christian times, both in Europe and in the Near East. The papers which reflect a merger between classicism and geotechnology, thus deal with (1) quarries from the Bronze Age to the Byzantine period, their technology and organization, (2) quarry prospection through satellite imaging, (3) dressing of artifacts near the quarries, (4) trade, availability and archaeological use of certain stones in antiquity, (5) determination of obsidian, flint, granite, marble, limestones, sandstones and arkoses from Europe, Asia Minor and the Near East by means of petrological and chemical analysis, trace element analysis, electron microprobe and stable isotope analysis, ESR spectroscopy, X-ray fluorescence and X-ray powder diffradtometry, mercury porosimetry, cathodoluminiscence, light diffustion from laser-irradiated stones, computer assisted assessment of coloured stones or amulti-method appraoch, and (6) provenance determination applied to ancient artifacts.The volume is highly recommended for those who wish to combine a journey into classical scholarship with geochemical sciences.

This issue of Aardkundige Mededelingen deals with industrial minerals, their resources, characteristics and applications. It is the result of an academic session on industrial minerals in honour of Em. Prof. Dr. R. Ottenburgs. The contributions are organized according to five topics. In a first part, 'The Industrial Mineral World', some considerations on our natural resources, their use and political impact are presented. In a second part of the study, 'Aggregates and Natural Building Stone', a number of case-studies on the use of industrial minerals as aggregate and ornamental or building stone are discussed. In a third part of the volume, 'Mortar, Cement and Concrete', the study of ancient mortars as well as exploratory research into new materials is illustrated. In a fourth session, 'Clays and Soils', environmental aspects of soils and the economical use of clay deposits are highlighted. In a fifth and final part of the book, 'Steel', the link between ores and industrial minerals is made. It is clear that the study of industrial minerals has many faces and covers many disciplines. The impact of industrial minerals on the world's economy, but also on the environment, cannot be emphasized enough. This book gives an overview of the wide and rich diversity of research currently performed in the realm of the industrial minerals.

One distinct feature of human society since the dawn of civilization is the systematic use of inorganic building materials, such as natural stone, unburnt and burnt soil, adobe and brick, inorganic binders like lime and cement, and reinforced concrete. Our heritage has cultural, architectural and technological value and preserving such structures is a key issue today. Planners and conservation scientists need detailed site surveys and analyses to create a database that will serve to guide subsequent actions. One factor in this knowledge base is an understanding of how historic materials were prepared and the crucial properties that influence their long-term behaviour. Any assessment of the way such materials perform must crucially be based on an understanding of the methods used for their analysis. The editors here add to the knowledge base treating the materials used in historic structures, their properties, technology of use and conservation, and their performance in a changing environment. The book draws together 18 chapters dealing with the inorganic materials used in historic structures, such as adobe, brick, stone, mortars, concrete and plasters. The approach is complex, covering material characterisation as well as several case studies of historic structures from Europe, including Germany, Ireland, Italy, Poland, Portugal, Scotland, Slovenia and Spain, and the My Sõn Temples in Vietnam. An equally important component of the book covers the analysis of materials, together with a treatment of sustainable development, such as the protection of monuments from earthquakes and climate change. The authors are all leading international experts, drawn from a variety of backgrounds: architecture, civil engineering, conservation science, geology and material science, with close links to professional organisations such as ICOMOS or universities and research centres throughout Europe. Audience: This book will be of interest to geologists, engineers, restorers, consulting engineers, designers and other professionals dealing with cultural heritage and sustainable development. Also graduate students in applied geo-science (mineralogy, geochemistry, petrology), architecture and civil engineering will find interesting information in this book.

Marble is one of the great veins through the architectural tradition and fundamental building block of the Mediterranean world, from the Parthenon of mid-fifth century Athens, which was constructed of pentelic marble, to Justinian’s Hagia Sophia in Constantinople and the Renaissance and Baroque basilica of St. Peter’s in the Vatican. Scholarship has done much in recent years to reveal the ways and means of marble. The use of colored marbles in Roman imperial architecture has recently been the subject of a major exhibition and the medieval traditions of marble working have been studied in the context of family genealogies and social networks. In addition, architectural historians have revealed the meanings evoked by marble revetted and paved surfaces, from Heavenly Jerusalem to frozen water. The present volume builds upon the body of recent and emerging research - from antiquity to the present day - to embrace a global focus and address the more unusual (or at least unexpected) uses, meanings, and aesthetic appeal of marble. It presents instances where the use of marble has revolutionized architectural practice, suggested new meaning for the built environment, or defined a new aesthetic - moments where this well-known material has been put to radical use.
