L'article décrit et expose les résultats de deux séries d'expériences de coulée de figurines en bronze suivant la méthode de la fonte à la cire perdue. Ces expérimentations avaient pour but d'essayer de reproduire les procédés d'élaboration et de coulée utilisés à l'époque minoenne et de préciser leur rôle et leur influence sur l'apparence finale des objets.

The ways in which the sciences have been delineated and categorized throughout history provide insights into the formation, stabilization, and establishment of scientific systems of knowledge. The Dresdener school’s approach for explaining and categorizing the genesis of the engineering disciplines is still valid, but needs to be complemented by further-reaching methodological and theoretical reflections. Pierre Bourdieu’s theory of social practice is applied to the question of how individual agents succeed in influencing decisively a discipline’s changing object orientation, institutionalisation and self-reproduction. (...) Through the accumulation of social, cultural and economic capital, they succeed in realising their own organisational ideas and scientific programs. Key concepts for the analysis include the struggle for power and resources, monopolies of interpretation, and the degree of autonomy. A case study from the Aachener Technische Hochschule shows that the consolidation of ferrous metallurgy can be conceived as a symbolical struggle between Fritz Wüst, professor for ferrous metallurgy, and the German Iron and Steel Institute, leading to a construction of a system of differences in which scientists accepted being scientists rather than entrepreneurs, and entrepreneurs accepted becoming entrepreneurs and renounced science.

Summary A study of the metallurgy and manufacturing techniques of a group of eight astrolabes (seven from Lahore, one attributed to India) using non-destructive methods has produced the earliest evidence for systematic use of high-zinc (α?+??) brass. To produce this alloy, the brass industry supplying the Lahore instrument makers must have co-melted metallic copper and zinc. This brass-making technology was previously believed to have been developed on an industrial scale in the nineteenth century in Europe. This work hypothesizes that (...) this technology was used in Lahore on an industrial scale as early as ad 1601. In addition, this work hypothesizes that the α?+?? brass alloy was used specifically for its ease in manufacturing the thin sheet brass required for astrolabe-component manufacture. (shrink)

E.F. Geoffroy's table of different relations ( rapports ) between different chemical substances is mainly based on empirical knowledge accumulated in 16th and 17th century metallurgy and pharmacy. The substances listed in the left half of the table were basic for the formation of salts which were produced for medical ends in the chemical-pharmaceutical practice of the 17th century. The right half of the table refers to substances and operations of metallurgy which had already been described in the (...) metallurgical writings of the 16th century. Even Geoffroy's ordering of the substances within the columns of his table has its origin in metallurgical and pharmaceutical practice. The key concept of the conceptual framework underlying the table and its commentary is the concept of chemical compound which emerged at the end of the 17th century. Geoffroy extends the range of application of this concept, which was first limited to chemical artefacts, to include natural bodies. Eliminating the peripatetical distinction between natural bodies and chemical artefacts he formulates a new research program, consisting in the determination of the laws of the relations ( rapports ) between different chemical substances.

At the beginning of the 20th century, research on material substances such as blood and metals was in high demand, as is apparent from the successful careers of the serologist Ludwik Hirszfeld (1884–1954) and the metallurgist Jan Czochralski (1885–1953). Both were leading experts of their time, their transnational biographies – spanning the German-speaking countries and Poland – were remarkably similar, and they both played important roles in the development of their respective disciplines. This paper explores how their contributions were closely (...) tied to the circulation of their respective research materials – blood and metals – and of knowledge about them throughout Europe and beyond. These examples forcefully demonstrate that, in order to fully understand how specific, widely accepted bodies of knowledge emerge, both local situations and the material conditions have to be considered. Drawing on Latour's actor-network theory, the transnational stories of serology and metallurgy demonstrate the range of human and non-human actors, practices, and techniques that contributed to the circulation of knowledge, to its successful application, and also to occasional failure in specific geographical and cultural contexts.

It appears likely that at its peak the classical economy was almost as large as that of Western Europe during the Industrial Revolution. The following review of the archeological and document evidence indicates that three events occurring in the first half of the first millennium BC trigger the emergence of a specialized and integrated classical economy after 500 BC: (i) growth in demand for silver as a medium of exchange in economies in the Near East; (ii) technical breakthroughs in hull (...) construction and sailing rig in merchant shipping of the late Bronze Age; (iii) perfection of ferrous metallurgy into the European hinterland. This last event raised agricultural productivity to a level capable of supporting the occupational specialization needed to sustain a vigorous trading economy. To these initial causes may be added the diffusion of alphabetic writing. While it did not create opportunities for long-distance trade, the diffusion of writing supplied the means of responding on a scale large enough economically to matter. (shrink)

Borrowed from metallurgy, the concept of fusion casting is a method in the study of the humanities. In light of fusion-casting, this paper reviews the longstanding weakness of comparative studies and the limitations of its naming. Because of the superficiality and farfetchedness in comparative studies, fusion-casting studies are imperative remedies so as to break the bondage of empiricism and analogies. In the trend of globalization, comparative studies will continue to play a role, but the inherent weakness, excessive use and (...) the low quality of such studies must be overcome. The case of fusion-casting studies is not intended to get rid of comparative studies. Rather, it is intended to increase the depth of the latter so that there shall be ground-breaking progresses and innovations. (shrink)

Why should anybody take an interest in philosophy? Is it just another detailed study like metallurgy? Or is it similar to history, literature and even religion: a study meant to do some personal good and influence our lives? In her last published work, Mary Midgley addresses provocative questions, interrogating the various forms of our current intellectual anxieties and confusions and how we might deal with them. In doing so, she provides a robust, yet not uncritical, defence of philosophy and (...) the life of the mind. This defence is expertly placed in the context of contemporary debates about science, religion, and philosophy. It asks whether, in light of rampant scientific and technological developments, we still need philosophy to help us think about the big questions of meaning, knowledge, and value. (shrink)

The ArgumentMost historians of science share the conviction that the incorporation of the corpuscular theory into seventeenth-century chemistry was the beginning of modern chemistry. My thesis in this paper is that modern chemisty started with the concept of the chemicl compound, which emerged at the end of the seventeenth and the beginning of the eighteenth century, without any signifivant influence of the corpuscular theory. Rather the historical reconstruction of the emergence of this concept shows that it resulted from the reflection (...) on the chemical operations in the sixteenth-century metallurgy and seventeenth-century pharmacy. I argue that the reversibility of these operations and their understanding as crafts (metallurgy) or chemical arts (pharmacy) were decisive factors for the emergence of the first ideas about chemical compounds in the seventeenth-century pharmaceutical works written by pharmaceutically trained authors, influenced by the Paracelsian image of nature. There is a direct line of descent from these authors to E.F.Geoffroy (1675–1742), who integrated the first scattered ideas of chemical compound into a general concept comprising chemical artefacts as well as natural bodies.

Jack Goody’s work on the origins, spatial extent and defining characteristics of modernity has vigorously questioned claims that only European history led to assorted modern characteristics: capitalism, science, democracy, romantic love, and inwardly-motivated personal restraint. He argues that many societies which experienced the Bronze Age urban revolution share certain important material similarities (and some differences) which set them apart from others, and are best understood by constructing an analytical grid rather than categorical stages. With respect to alleged affective differences, Goody (...) takes a more strongly relativist stance, rejecting any developmental divide in the prevalence of romantic love, internalized self-discipline, etc. These useful steps nonetheless generate new problems. One concerns the relationship between material/technical changes, which seem to suggest a few very general historical periods (one marked by early metallurgy, writing, etc., and another by the modern energy revolution), and affective traits, which have no history in this schema. A second concerns periodization itself; while agreeing that periods defined by the experience of one region (e.g. a feudal era) are usually unhelpful, some general terms (such as early modern) do seem essential for conceptualizing developments that, though less epochal than writing or fossil fuels, are nonetheless important.

The ArgumentBoth “early chemistry” and “modern concepts” are imprecise. The earliest references to the materials involved in metallurgy, painting, ceramics, and the like, reveal an awareness that one group of materials were called “salts” because of their similarities. I consider this a chemical “concept.” Seeking another example I claim to have found it in the so-called “mineral acids.” The evidence for the existence of this concept is cumulative during the period just before the emergence of “modern chemistry,” of which (...) it may be considered a cause. That evidence is particularly found in the literature of pharmacy and of medicine, both of which belong to the practical arts. (shrink)

The contributions of Portuguese and Spanish sixteenth century science and technology in fields such as metallurgy, medicine, agriculture, surgery, meteorology, cosmography, cartography, navigation, military technology, and urban engineering, by and large, have been excluded in most accounts of the Scientific Revolution. I review several recent studies in English on sixteenth and seventeenth century natural history and natural philosophy to demonstrate how difficult it has become for Anglo-American scholarship to bring Iberia back into narratives on the origins of "modernity." The (...) roots of this exclusion, to be sure, hark back to the Protestant Reformation and the Enlightenment. The oversight is unfortunate for it has blinded scholars to the fact that the Iberians first created a culture of empirical, experimental, and utilitarian knowledge-gathering of massive proportions that did not get its cues from the classics or the learned, but from merchants, enterprising settlers, and bureaucrats. The Portuguese and the Spanish confidently saw themselves as the first "moderns," superseding the ancients. The English were the first to recognize this fact and they sought to imitate the new institutions of knowledge-gathering created by the Iberians. I demonstrate, for example, the Iberian origins of many of Francis Bacon's epistemological insights and metaphors. Spanish and Portuguese scholars have long been making this point. I therefore introduce English-speaking audiences to some of the most recent scholarship by Spanish scholars on sixteenth century Iberian science and technology. (shrink)

En este artículo de investigación se muestra, que durante la fabricación de hierro, las escorias han sido una fuente información del producto obtenido. Esto aplica a toda la historia de la fabricación de este metal desde el inicio de la edad del hierro. Los estudios en este campo se conocen como arqueo de metalurgia y se inicia desde la paleo metalurgia hasta el presente. Las escorias primitivas obtenidas a partir de su separación de la masa de hierro sólida obtenidas en (...) procesos muy primitivos y más modernas como la forja catalana. Estudios petrográficos, de difracción de rayos X y de fluorescencia de rayos x, han revelado la existencia fayalita, en escorias siderometalúrgicas antigüas a temperaturas por debajo del punto eutéctico,deducidas como entre 1150°C y 1200°C. Más recientemente, la presencia de fayalita ha sido revelada en procesos de reducción operando con temperaturas menores a los 900°C.

According to Diderot's article "Art" in the Encyclopédie, secrecy is frequently related to guilds and refers to monopolizing practices and "routine". It appears therefore as an obstacle to innovation. But may we consider secrecy exclusively in this negative light? Studies on mining and metallurgy provide us with a different perspective, for they show how the protection of secrets from the gaze of outsiders also allowed for technical exchanges between the craftsmen themselves and thus implied a certain measure of technical (...) openness. From this point of view, it seemed interesting to look also at the urban craftsmen's practices, the so-called "Metiers jurés." A micro-historical study of guilds in a small town of mid-eighteenth century France, presented in this essay, shows that things were indeed in a state of flux. On the one hand, the very ritualistic practice of producing a chef d'aeuvre, which included even the temporary confinement of the candidate, was still in existence. Secrecy still formed a part of the qualifying process of urban artisans. On the other hand, both the ritual and the chef d'aeuvre were undergoing change, the ritual developing more slowly than its content. In the process, secrecy tended to become pure dissimulation, allowing in fact the spread of a practice like subcontracting, which was officially prohibited. (shrink)

Casting Techniques in Minoan and Mycenaean Crete. I. The casting tools Studies on copper and bronze metallurgy in the prehistoric Aegean area generally focus on metal objects but neglect the bronzesmith tools : crucibles, molds and ventilation systems (“ tuyères”, bellows…). However, their study provides new information on both the technical processes of making a metal object and their evolution, and the existence of technical traditions and “ savoir-faire” of these bronzesmiths. The first part of this study is devoted (...) to the examination of the corpus of Cretan tools from the EBA to the LBA highlighting their specific features and functions, while the resulting synthesis— forthcoming in a future issue— will focus on the technical process and changes in casting activities and the “ savoir-faire” of the Cretan bronzesmiths.

For a deep understanding of Beijing-Tianjin-Hebei collaborative innovation, we detected and visualized the communities of innovation in BTH Urban Agglomeration based on the patent cooperation network. China Patent Database was connected with Business Registration Database and the Tianyan Check to achieve the geographical information of organizational innovators. Spinglass algorithm was applied and ultimately 12 communities of innovation were detected. Based on the different structure characteristics, we further clustered the 12 communities into four typical structures that are hierarchical, single-center, polycentric, and (...) flat structures. The hierarchical structure is usually large in scale and the cooperative intensity is relatively high. Single-center structure has a center with a high proportion of centrality and the cooperative intensity is relatively low. Polycentric structure has multiple centers with similar proportions of centrality. Flat structure is usually small in scale and has no obvious network center. In the patent cooperative network of BTH Urban Agglomeration, universities and state-owned enterprises occupied the centers and acted important roles to connect other organizations. Some communities of innovation showed significant industry characteristics, mainly involving six industry fields that are electric power, construction, petroleum, metallurgy and materials, municipal transportation, and railway. From the geographical perspective, some communities manifested local attributes and some demonstrated cooperation between regions. Beijing was the center of the Beijing-Tianjin-Hebei patent cooperation network. Compared with the pair of Beijing-Tianjin and the pair of Beijing-Hebei, Tianjin and Hebei were not closely connected. In the future, Beijing-Tianjin-Hebei collaborative innovation should strengthen cooperation between Tianjin and Hebei. (shrink)

This paper discusses two methodological notions, the concepts Gegenprobe (countercheck) and Gegenversuch (counter-trial), which were widely applied, discussed, relied upon, and defended in German-language writings about empirical inquiry. In the decades around 1800, they were common in physiology; medicine; agriculture; chemistry; various technologies, such as printing, metallurgy, and mining; accounting; and legal and political argumentation. The ubiquity of those concepts signals a broad concern with securing empirical findings and empirical knowledge. Gegenproben and Gegenversuche – the terms as well as (...) the practices – are evidence for the close connection among explicitly knowledge-seeking endeavors and crafts and technologies. Physiological experiments, chemical analyses, agricultural or vaccination trials were indebted to applied and practical procedures of making and assaying. What united these different fields was the fact that the problems that had to be solved were very complex yet at the same time of immediate relevance to everyday lives (like diseases or crops) or highly controversial (like vital forces or spontaneous generation). We know that late eighteenth-century and early nineteenth-century practices of inquiry were firmly embedded in applied, technical contexts; this essay shows that methodological notions were anchored in applied, technical contexts as well.

The article resonates Plato's ideas on education and art. In the Apology, Socrates describes his life's mission of practicing philosophy as aimed at getting the Athenians to care for virtue; in the Gorgias, Plato claims that happiness depends entirely on education and justice; in the Protagoras and the Meno, he puzzles about whether virtue is teachable or how else it might be acquired; in the Phaedrus, he explains that teaching and persuading require knowledge of the soul and its powers, which (...) requires knowledge of what objects the soul may act on and be acted on by which, in turn, requires knowledge of nature. The article also looks at musical and gymnastic education's effects on the soul using images from metallurgy and dyeing wool, saying that prerational souls are “most malleable and take on any pattern one wishes to impress on them.”.

The actuality of the research topic is that for the development of Ukraine it is necessary to take into account the indisputable fact that globalization together with the information revolution has created new conditions for all types of life. Humanity continues to grow quantitatively and increase the number of independent states whose citizens use the national languages. The purpose of the study is a critical analysis of the reasons for the unprecedented complexity of language changes in Ukraine after the collapse (...) of the Soviet Union and the restoration of its independence. Objectives of the study - to identify the deep causes of the loss of the truth of Ukrainians about their linguistic past; to prove on the basis of the latest scientific discoveries the peculiarity of the linguistic contribution of the ancestors of Ukrainians to the emergence of the Indo-European linguistic family thousands of years ago; to fulfill the forecast for the future of international languages. The methodology of the research is the noointegral, systemic and noohistorical methods that allow a newer way to analyze the affinity of the Ukrainian language with English and to make a forecast of changes in the role of the English language in the future. Presenting main material: the result of the study is the discovery of evidence that the Ukrainian language is not just a little branch of the Russian language, but a transformed primary Indo-European language. The scientists from the West were proved that Ukrainians were the part of the inventors of agriculture in Levant. During the movement on the West they chose life on the black earths of Ukraine, joined with the Arians and created the civilization "Trypillya-1". Trypillians domesticated a horse, invented a wheel, created a metallurgy of bronze and formed the economic zone of the Greate Trypillya between the Carpathians and Western Siberia. All the common words of today about 400 Indo-European languages are a cloud of tags spread from the Great Trypillya. The article is devoted to the concept of "international language". The analysis of contemporary world language changes is carried out in order to assess the possibility of converting English into a global international language. Examples of the growth and decline of languages of certain peoples in the past are considered. The data on evolution and changes in the international language ranking in the New Times are given. The facts of the temporary leadership of the French, German and Russian languages are revealed and the main reasons for their retreat and decline are indicated. The reasons for the global use of English in the twentieth century are explained, but the assumption about the impossibility of its transformation into the universal language of humanity in the future is expressed. A forecast of the influence of progress in computer technologies and artificial intelligence on the ways of using English and other languages is made. The fact of the appearance of the first version of the computer multilingual translator Travis-1 is noted and its rapid improvement and inclusion in the software of near-future mobile devices, which spread on the planet in billions of copies, is envisaged. Conclusions - formulated suggestions for plans for the development of the education system in Ukraine. It is proposed to use positive experience in Scandinavian countries - Sweden and Finland in modernizing the teaching of English and other foreign languages. (shrink)

The aim of this work is to provide a preliminary analysis of a much more far-reaching investigation into the relationship between technology and philosophy. In the context of the contemporary German thought, the author compares the different positions of Karl Marx, Martin Heidegger, Ernst and Friedrich Jünger, Arnold Gehlen and Gunther Anders. The term “machine” is used precisely to mean that complex material device assembled in the last quarter of the 18th century as a result of the definitive modern refinement (...) of certain fundamental technologies, i.e. metallurgy, precision mechanics and hydraulics. The “machine” discussed here arrived on the scene of man’s history when the processes of spinning and weaving were entrusted to semi-automatic means; when the water wheels used in mills, hitherto always made of wood, were supplanted by the metal levers of the steam engine; and especially when the steam engine was connected to the weaving frames, to the metalworking hammers, and to other machines used to manufacture other machines in an endless reiteration of assemblies and applications, the enormous outcome of which is what subsequently came to be described as “mass production”. The philosophers discussed here were also dealing with the type of machine described above and in their works she we can identify three model images of this idea of machine. These images have been drawn on at various times, also outside the realms of philosophy, and they still provide the backdrop for our knowledge of the machine, which has circulated in a great variety of languages.

The articles in this collection were all selected from the first five volumes of the Journal of Dialectics of Nature published by the Chinese Academy of Sciences between 1979 and 1985. The Journal was established in 1979 as a comprehensive theoretical publication concerning the history, philosophy and sociology of the natural sciences. It began publication as a response to China's reform, particularly the policy of opening to the outside world. Chinese scholars began to undertake distinctive, original research in these fields. (...) This collection provides a cross-section of their efforts during the initial phase. To enable western scholars to understand the historical process of this change in Chinese academics, Yu Guangyuan's `On the Emancipation of the Mind' and Xu Liangying's `Essay on the Role of Science and Democracy in Society' have been included in this collection. Three of the papers included on the philosophy of science are discussions of philosophical issues in cosmology and biology by scientists themselves. The remaining four are written by philosophers of science and discuss information and cognition, homeostasis and Chinese traditional medicine, the I Ching (Yi Jing) and mathematics, etc. Papers have been selected on the history of both classical and modern science and technology, the most distinctive of which are macro-comparisons of the development of science in China and the west. Some papers discuss the issue of the demarcation of periods in the history of science, the history of ancient Chinese mathematics, astronomy, metallurgy, machinery, medicine, etc. Others discuss the history of modern physics and biology, the history of historiography of science in China and the history of regional development of Chinese science and technology. Also included are biographies of three post-eighteenth-century Chinese scholars, Li Shanlan (1811-1882), Hua Hengfang (1833–1902), and Cai Yuanpei (1868–1940), who contributed greatly to the introduction of western science and scholarship to China. In addition, three short papers have been included introducing the interactions between Chinese scholars and three great western scientists, Niels Bohr, Norbert Wiener, and Robert A. Millikan.

ABSTRACTWhile the emergence of a new scientific culture in 16th-century Europe is well known, the role of the actors of the Hispanic New World in this time of renewal of knowledge has long been judged marginal for two reasons: first, because the strong presence of the Inquisition in the Hispanic World has been considered by historians to have been an obstacle for research or scientific innovation; and second, because the discontinuity of the territories of the Hispanic Monarchy and the problem (...) of distances between Spain and the New World have long been interpreted in ways that suggest the marginality and peripheral status of the American colonies. However, some works counterbalance this dismissal and shed new light on the scientific activity of the Hispanic New World. This is the case with the treatise Arte de los Metales, by the secular priest Alvaro Alonso Barba, which would achieve remarkable fame and circulation, and would become a seminal work in the fields of metallurgy and mining until the mid-1700s. The article demonstrates that this treatise also presents ideas that can be traced back to a set of Paracelsian ideas combining alchemy, pharmacopoeia, and medicine, and studies specific examples of these ideas – the description of three fundamental substances as components of all matter, references to Epatica sulfuris, an oil capable of turning silver into gold and curing certain diseases; and the use of antimony – that together testify to the spread of the ideas of Basil Valentine and of Paracelsian influences. From this point of view, Arte de los Metales can be viewed as part of a tradition unexpectedly renewed by the author through many observations based on his own work in Peru and the discoveries he made thanks to alternative techniques. This demonstrates the richness and diversity of knowledge rooted in the New World, and links Alonso Barba’s scholarly activity to some of the great schools of thought that spanned the Early Modern European world.

In lieu of an abstract, here is a brief excerpt of the content:Purity and Pollution: Resisting the Rehabilitation of a VirtueAmy Mullin“Purity” is a term used infrequently in contemporary academic literature. A survey of periodical indexes for the past ten years shows that references to purity occur predominantly in metallurgy. Purity is an increasingly important topic in anthropology, religious studies, and history, but it is a decidedly rare concern in philosophy. In my most recent search I found three references.Yet (...) “purity” was once a recurrent term in the philosophical tradition ranging from Plato through Augustine and Kant to Kierkegaard. Today when we encounter the many references to purity in the history of philosophy we too often filter them out. We assume either that “pure” is a generic term for good, or, in what seems a more knowing and sophisticated response, we read “pure” as a code term for chastity or sexual morality, the elimination, suppression or control of sexual desire. In both cases purity is written off either as a generic or as an old fashioned and rather embarrassing virtue. Hence it seems there is little reason for contemporary philosophical investigation into the rhetorical use of the language of purity and pollution.Three assumptions account for the lack of contemporary philosophical interest in the topic. First, it is assumed that purity is no longer a concern in twentieth-century philosophy. Second, purity in historical discourse is considered to be limited to a prudish or downright misogynist hostility to sex. Third and finally, it is assumed that the work historians and anthropologists have done recently into connections between purity beliefs and practices and social cohesion is irrelevant for philosophy. This is because purity in philosophy is supposed to be a resolutely individualist virtue, having little or nothing to do with unified and coherent communities.There are elements of truth to all three beliefs, but they also contain important distortions of the truth. As regards the first assumption, purity remains a concern in contemporary aesthetics, where it often means roughly something like a priori and apolitical; but I am interested in whether the concern with purity has survived in philosophies with ethical implications. [End Page 509] Here it is my contention that authenticity is the twentieth-century descendant of the virtue of purity.Second, there is much more to the rhetoric and practices of purity than concern with the sexual dimension of life, though this is a key aspect of most, and the beliefs and practices are often misogynist. There have been numerous anthropological documentations of ways in which purity beliefs, particularly an emphasis on sexual purity, are used to control women. Santi Rozario’s work, for instance, makes this point in her analysis of contemporary Bengali village life. 1 The connection between the language of purity and the practice of female circumcision, which I will not discuss in this paper, is in itself evidence enough of connections between purity beliefs and practices harmful to women. 2 However, I hope to show that there is more to purity than misogyny. Purity most basically is about order, both social and personal. 3My response to the second assumption, that purity masks an obsession with sexual control, indicates the source of my disagreement with the third, the contention that purity in philosophy is exclusively an individual virtue. Communal beliefs and practices associated with the language of purity and pollution are relevant to the philosophical treatment of purity because of the presence in both the practices and the philosophies of an interplay between social and personal order. As a result I believe an understanding of the dynamics of beliefs about purity in social practice can inform a philosophical concern with purity.First I investigate shifts in beliefs and practices concerning purity and pollution. I will concentrate on three models: ancient Greek (from the eighth to the third century BC), biblical to Talmudic Judaism (from the third century BC to the third century AD), and early Christian (from the first to the fifth century AD). These represent three traditions which have played a very significant role in shaping western civilization, theology, and philosophy. 4 They were also frequently interrelated in this period, as Christian and Jewish Platonists writing in Greek attest and of course as...

Incomplete Archaeologies takes a familiar archaeological concept--assemblages--and reconsiders such groupings, collections and sets of things from the perspective of the work required to assemble them. The discussions presented here engage with the practices of collection, construction, performance and creation in the past (and present) which constitute the things and groups of things studied by archaeologists--and examine as well how these things and thing-groups are dismantled, rearranged, and even destroyed, only to be rebuilt and recreated. The ultimate aim is to reassert (...) an awareness of the incompleteness of assemblage, and thus the importance of practices of assembling (whether they seem at first creative or destructive) for understanding social life in the past as well as the present. The individual chapters represent critical engagements with this aim by archaeologists presenting a broad scope of case studies from Eurasia and the Mediterranean. Case studies include discussions of mortuary practice from numerous angles, the sociopolitics of metallurgy, human-animal relationships, landscape and memory, the assembly of political subjectivity and the curation of sovereignty. These studies emphasise the incomplete and ongoing nature of social action in the past, and stress the critical significance of a deeper understanding of formation processes as well as contextual archaeologies to practices of archaeology, museology, art history, and other related disciplines. Contributors challenge archaeologists and others to think past the objects in the assemblage to the practices of assembling, enabling us to consider not only plural modes of interacting with and perceiving things, spaces, human bodies and temporalities in the past, but also to perhaps discover alternate modes of framing these interactions and relationships in our analyses. Ultimately then, Incomplete Archaeologies takes aim at the perceived totality not only of assemblages of artefacts on shelves and desks, but also that of some of archaeology's seeming-seamless epistemological objects"--From publisher's website.

In 1914, Max von Laue was awarded the Nobel Prize “for the discovery of X-ray diffraction by crystals,” followed by the 1915 Nobel Prize to William Henry Bragg and William Lawrence Bragg “for their services in analysis of crystal structure by means of X-rays.” And these early Nobel prizes marked only the beginning of (...)

A 100 years after Laue’s Nobel Prize and 50 years after another Nobel Prize to Dorothy Hodgkin “for her determination by X-ray technique of the structures of important biochemical substances,” the UN proclaimed 2014 the International Year of Crystallography. “In all, 45 scientists have been awarded over the past century for work that is either directly or indirectly related to crystallo ..

In the 1980s, the archaeologist Merrick Posnansky implored Africa-trained scholars to investigate the Caribbean and use their training to reframe the construction of the African diasporic experience. This paper is based on research that responded to Posnansky’s challenge. Employing archaeology, community-based fieldwork, oral traditions, gender analysis, and archival sources on both sides of the Atlantic, the paper explores the history of African metallurgy, including the author’s personal research experiences in West Africa and the Caribbean. It argues for incorporating the (...) knowledge and skills of African people into a global history of iron technology. It demonstrates how the spatial and social characteristics of iron smelting and refinement have implications for the unfolding of late eighteenth-century forging in Jamaica and industrial growth in other parts of the Atlantic world. While ideas and knowledge operated in the meanings and metaphors found within both material and unseen realms, the eventual reconceptualization of this intertwined past must remain grounded in claims that can be supported by evidence. Connecting kitchens and crucibles, the study argues for an extended family of technological history. Just as understanding the global history of iron production requires attention to Africa, the inverse is simultaneously true: Africa and its history are firmly integrated in global history, including the history of the industrial revolution.
