THE COUNTED TIME: TECHNICAL TEMPORALITIES AND THEIR CHALLENGES TO HISTORY

One of the main debates regarding historical representation within digital media concerns narrative, particularly the difficulty in articulating it. Digital technologies are usually presented as opposed to linear, written narratives, which is of consequence to historical writing. Despite the many merits of scholarly approaches that try to circumvent this difficulty, the lack of theoretical understanding of the categories implied in such discussions is noticeable. To counter this, this article addresses the relationship between time, technics, and narrative. I contend that the challenges of crafting narratives in digital media conceal a problem pertaining to the relationship between time and technics. Drawing on Paul Ricoeur's work on narrative, Jimena Canales's studies of the history of science, Wolfgang Ernst's and Yuk Hui's discussions of technical temporality, and Bernard Stiegler's understanding of the relationship between time and technics, I argue that it is the temporality imbued in the workings of technical objects (such as computers) that renders them averse to narrative. In making this argument, I employ the notion of “counted time” (in contrast to Ricoeur's “narrative time”) to denote a temporal mode that, despite its intersections with social, human temporality, is alien to narrative.     

Chemical and isotopic signatures of Na/HCO3/CO2‐rich geofluids,North Portugal

Geochemical and isotopic studies have been undertaken to assess the origin of CO₂‐rich waters issuing in the northern part of Portugal. These solutions are hot (76°C) to cold (17°C) Na–HCO₃ mineral waters. The δ²H and δ¹⁸O signatures of the mineral waters reflect the influence of altitude on meteoric recharge. The lack of an ¹⁸O‐shift indicates there has been no high temperature water–rock interaction at depth, corroborating the results of several chemical geothermometers (reservoir temperature of about 120°C). The low ¹⁴C activity (up to 9.9 pmC) measured in some of the cold CO₂‐rich mineral waters (total dissolved inorganic carbon) is incompatible with the presence of ³H (from 1.7 to 4.1 TU) in those waters, which indicates relatively short subsurface circulation times. The δ¹³C values of CO₂ gas and dissolved inorganic carbon range between ?6‰ and ?1‰ versus Vienna‐Peedee Belemnite, indicating that the total carbon in the recharge waters is being diluted by larger quantities of CO₂ (¹⁴C‐free) introduced from deep‐seated (upper mantle) sources, masking the ¹⁴C‐dating values. The differences in the ⁸⁷Sr/⁸⁶Sr ratios of the studied thermal and mineral waters seem to be caused by water–rock interaction with different granitic rocks. Chlorine isotope signatures (?0.4‰ < δ³⁷Cl < +0.4‰ versus standard mean ocean chloride) indicate that Cl in these waters could be derived from mixing of a small amount of igneous Cl from leaching of granitic rocks.     

A COMBINED MULTI‐ANALYTICAL APPROACH FOR THE STUDY OF ROMAN GLASS FROM SOUTH‐WEST IBERIA: SYNCHROTRON μ‐XRF,EXTERNAL‐PIXE/PIGE AND BSEM–EDS

An integrated, multi‐analytical approach combining the high sensitivity of SR‐μXRF, the light element capability of PIXE/PIGE under a helium flux and the spatial resolution of BSEM + EDS was used to characterize chemical composition and corrosion of glass samples (first to fourth centuries ad ) from an important, but scarcely investigated, Roman region of south‐west Iberia (southern Portugal). The geochemical trends and associations of major, minor and trace elements were investigated to shed light on production techniques, the provenance of raw materials and decay mechanisms. The results, while confirming a production technique common to Roman glasses throughout the Empire—that is, a silica‐soda‐lime low‐Mg, low‐K composition, with glass additives as colouring and/or decolouring agents (Fe, Cu, Mn, Sb)—show at one site high Zr–Ti contents, suggesting a more precise dating for these glasses to the second half of the fourth century. The Ti–Fe–Zr–Nb geochemical correlations in the pristine glass indicate the presence of minerals such as ilmenite, zircon, Ti‐rich Fe oxides and columbite in the sands used as raw materials for the glass former: these minerals are typical of granitic‐type source rocks. The unusually high K content in the corrosion layers is consistent with burial conditions in K‐rich soils derived from the alteration of 2:1 clays in K‐bearing rock sequences.     

THE LIMITS OF OTTOMAN PRAGMATISM

In this paper I reflect critically on the concept of pragmatism as it is used in Ottoman historiography. Pragmatism has gained increasing currency over the last ten to fifteen years as one of the defining features of the Ottoman polity. I argue that unless it is properly defined from a theoretical‐philosophical perspective, and carefully contextualized from a historical perspective, pragmatism cannot be used as an explanatory or comparative category. When used as a framework of explanation for historical change, pragmatism blurs more than it clarifies an essential aspect of the Ottoman polity that it seeks to define, namely, the political. It is essential to reflect on the difference between the political and politics because whereas the political refers to the configuration of the power relations that organize a society as a legitimate entity, politics refers to the strategies, practices, institutions, or discourses whose purpose is to construct and retain hegemony within a polity. Through an analysis of the concept of pragmatism in Ottoman historiography, I show that for most proponents of Ottoman pragmatism, pragmatism pertains to politics rather than to the political. From a perspective rigorously confined to political theory, I argue that much like the discourse of modern tolerance, pragmatism in Ottoman historiography posits a problematic periodization, relegates the political to the background, and depoliticizes essential power relations.     

COPPER AGE DITCHED ENCLOSURES IN CENTRAL IBERIA

Summary. The interpretation of European Neolithic enclosures must take account of their wide variability in chronology, size, shape, topographical position and material. Such interpretations should rely on the comparative analysis of the processes at work in particular regions. Newly recovered data from small early third millennium cal BC ditched enclosures in central Iberia, with high densities of features and domestic refuse, support the hypothesis of permanent habitation. This paper argues that the variability in late Neolithic–Chalcolithic enclosures throughout Iberia is a result of the cycling of fission and fusion characteristic of segmentary social dynamics.

SHAFT‐HOLE AXES FROM CAPUT ADRIAE MADE FROM AMPHIBOLE‐RICH METABASITES: EVIDENCE OF CONNECTIONS BETWEEN NORTHEASTERN ITALY AND CENTRAL EUROPE DURING THE FIFTH MILLENNIUM BC

Here we show the results of a study concerning a small group of shaft‐hole axes found in northeastern Italy, made from amphibole‐rich metabasites, fine‐grained and free of phenoblasts. The main mineral phases are amphibole, ranging from actinolite to hornblende, and plagioclase (An_10–15 and An_70–77). The amphiboles generally show a needle shape and are often radially arranged. Quartz is present in thin veinlets, while ilmenite is widespread in small patches. The petrographic and geochemical features suggest that the axes originate from the southern thermal aureole of Tanvald granite in northern Bohemia. In accordance with this provenance, the typology of the tools shows similarities with the perforated shoe‐last axes spread across Central Europe during the fifth millennium bc and made from similar raw material. For the first time, these axes give evidence of long‐distance (about 800 km) contacts between northeastern Italy and Central Europe during the Neolithic.
