Late-Occurring Handaxes in Korea: Their Homogeneity and Variability

Bifacially worked tools, which are formally categorized as handaxes, are increasingly found in Korea (present-day South Korea). By reviewing recently updated literature, this paper argues that Korean handaxes are unlikely to be true Acheulean handaxes from west of the Movius Line (ML), only partly sharing morphological affinities. A growing body of archaeological data in Korea provides an opportunity for a close examination of the enduring questions, although it does not offer straightforward answers. Korean handaxes show juxtaposed features; variables do not consistently match the pro and cons of affinity of the handaxes from west of the ML. The partial overlap of shapes with the specimens from the neighboring region and from west of the ML is not evidence for cultural transmission of tradition; therefore, the historical lineage across time and space ought to be reconsidered.     

The composition of colourless glass: a review

A total of 1496 investigated colourless glass analyses have been collected with the aim of achieving a clear geographical, typological, chronological and compositional overview on this particular type of glass. Based on manganese and antimony contents, four main groups were characterised: naturally colourless, Mn-decoloured, Sb-decoloured and Mn/Sb-decoloured. Main achievements relates to the chronological distribution of manganese and antimony technologies, the former being associated to a long lasting technology which culminated during the Late Antique period while the latter being practically absent after the 8^th century AD, being at its acme during the Roman imperial period. Except for naturally colourless glass, glass-making technology mostly implied the use of impure sands and natron, relegating the other components to a virtually irrelevant ?presence?, except during the  Late Antique and Medieval periods.     

Disclosing mineralogical phases in medioeval iron nails by non-destructive neutron techniques

There is not only one methodology for the study of mineralogical phases in archaeological samples. In this paper, we discuss a strategy applied to ancient iron nail samples completely based on non-destructive analyses. The archaeological samples come from the archaeological site of Valle delle Forme (province of Brescia–Italy) and date back to the 1300–1400 ad. Neutron-based techniques, like time-of-flight neutron diffraction and neutron tomography, have been used to determine the mineralogical composition and the structure of nails. An independent check for the assessment of the presence of different mineralogical phases was given by Raman spectroscopy. The combination of different non-destructive techniques has provided very useful information on their chemical composition, nature of the patina and corrosion features of the nails (also in the bulk of the samples).     

New compositional data on ancient mortars from Hagia Sophia (Istanbul,Turkey)

This study shows the results of a multidisciplinary collaboration between the University of Calabria (Italy) and the National Autonomous University of Mexico (UNAM), about the compositional characterization of some mortars taken from Hagia Sophia in Istanbul (Turkey), one of the most important buildings in antiquity. Twenty samples of joint mortars were analysed by micro-chemical analyses (SEM-EDS), X-ray powder diffraction (XRPD), optical microscopy (OM) and transmission electron microscopy (TEM). The compositional study allowed us to define, with more detail, the construction phases of the fifth, sixth and tenth century. The petrographic analysis in thin section by optical microscopy showed four typologies of sands, used as aggregate, with specific compositional features. SEM-EDS analyses and TEM observations of the binder around the ceramic fragments of the aggregate showed the presence of different morphologies of single C-S-H compounds.     

FTIR imaging and HPLC reveal ancient painting and dyeing techniques of molluskan purple

Fourier transform infrared spectroscopy and imaging coupled to optical microscopy, scanning electron microscopy coupled to energy dispersive x-ray spectroscopy and high-performance liquid chromatography (HPLC) coupled to diode-array detection are used to investigate two samples removed from a painted decoration of a burial kline and a textile fragment, both found in Koru tumulus (fifth century BCE) in Daskyleion. Tyrian purple and kaolinite were identified in both samples, thus suggesting that the aluminosilicate compound had an important role in the applied painting and dyeing processes. The textile fragment is composed of undyed cotton and silk yarns dyed with the molluskan dye. The relative compositions of the molluskan materials used in the two archaeological objects are similar and comparable with the corresponding composition measured for a purple sample originated from Murex trunculus mollusks according to the HPLC results. This result is supported by principal component analysis (PCA) which, furthermore, takes into account the relative compositions of the extracts of the three Mediterranean mollusks, published in previous reports.     

The use of different amber sources in Italy during the Bronze Age: new archaeometric data

The production of amber ornaments occurred in Italy during the Eneolithic (E)–Early Bronze Age (EBA), although very few beads from the Italian peninsula have been found and analysed. The number of data available for provenience study of Bronze Age ambers is larger, but still a precise picture of when and to what extent the local sources of amber were exploited is lacking. In the present work, 22 amber finds from six Sicilian sites have been studied and analysed by infrared spectroscopy, in particular with DRIFT (diffuse reflectance infrared Fourier transformed) analyses. The amber samples are dated between the Eneolithic and the Final Bronze Age–Early Iron Age and are from the collections of the P. Orsi Museum, in Syracuse (Sicily). The data show that only simetite was used in South Italy in the Late Eneolithic (LE)–EBA. In the Bronze Age, the exploitation of simetite shows different intensity in different chronological phases. The results are discussed in comparison with the information available for coeval European ambers.     

Changes in crop cultivation during the last five centuries before the Roman conquest: archaeobotanical investigation in the Clermont-Ferrand basin,Massif Central,France

For several decades, a growing number of protohistoric sites in Auvergne (Massif Central, France)—mostly excavated through preventive archaeology—have been subject to the collection of archaeobotanical analysis. This study presents the archaeobotanical results from ten La Tène sites dating from the last five centuries before the Roman conquest. In addition to providing an inventory of taxa, this paper concerns crops and crop cultivation methods. These results are interpreted in a wider context, dealing with crop husbandry, arable farming, storage and consumption practices. The sites are located in the Limagne plain within a 50-km radius around the city of Clermont-Ferrand. A total of 23,579 carpological remains were identified from 163 sediment samples totalizing a volume of 1096 l. Comparable to other sites in Gaul, the spectrum of cereals and pulses is restricted. Spelt (Triticum spelta), einkorn (Triticum monococcum) and foxtail millet (Setaria italica) are disappearing or becoming rare. A better control of agricultural techniques and increased yields is supposed during the ca. five centuries of the La Tène period. Mixed cultivation is hereby replaced by the sowing of monocrops. At the beginning of this period, farming systems are dominated by a polyculture of cereals and pulses. They become more specialized during the last two centuries before the Roman conquest; diversity of cereals and pulses is decreased.     

Experimental and archaeological investigations of backed microlith function among Mid-to-Late Holocene herders in southwestern Kenya

This study takes an experimental and comparative approach in order to evaluate the circumstances driving the deployment of microlithic tool technologies by food-producing mobile herders during the Mid-to-Late Holocene in southern Kenya. The predominately obsidian microliths used by contemporaneous, but culturally distinct, herding communities were replicated and used as arrow tips in archery experiments and within composite knives used in animal processing. This allowed for patterns of damage associated with production, different forms of projectile use, and butchery to be identified on microlithic specimens and evaluated against each other to assess the criteria for diagnostic macrofracture and wear patterns reflective of each activity. Experimentally generated criteria were used to identify the most likely functions for microlithic tools in three archaeological assemblages belonging to early Kenyan pastoralists. The analyses showed that while the same microlithic form is shared by culturally distinct groups across a wide time range, these tools were being used to vary different functions that do not clearly correlate with subsistence economy, culturally affiliation, or time period. Environmental variability and instability throughout the Late Holocene likely contributed to the persistence of highly adaptable microlithic toolkits. These data contribute to ongoing dialogues on the emergence and evolution of microlithic toolkits.     

Multi-technique investigation of historical Chinese dyestuffs used in Ningxia carpets

In this article, an extensive work is presented concerning the characterization with both chromatographic (high-performance liquid chromatography) and spectroscopic (surface-enhanced Raman spectroscopy and visible reflectance spectroscopy) techniques of historical Chinese dyestuffs in several carpets, mostly coming from the Ningxia region in Northern China and dating to the seventeenth–nineteenth centuries. Notably, the color of the background of these fine artifacts has been an object of debate since, while being depicted as bright red in the ancient iconography, nowadays it appears as orange/yellow. Therefore, in addition to the identification of all the colorants used in the carpets, the present study investigated the reasons of this apparent inconsistency, pointing out an explanation based on the joined use of the yellow dye obtained from the pagoda tree and a “fugitive” dye obtained from brazilwood.     

Paleodietary analysis of the sacrificial victims from the Feathered Serpent Pyramid,Teotihuacan

The consumption of different types and quantities of food frequently serves as a practice that expresses and reinforces social distinctions among individuals within complex societies. This study explores the dietary behavior of probable sacrificial victims interred within the offering complex underlying the Feathered Serpent Pyramid as a line of evidence concerning the identities and life experiences of individuals selected for inclusion within one of Teotihuacan’s public monuments. Stable carbon, nitrogen, and oxygen isotope values from rib samples of 12 individuals within the Feathered Serpent Pyramid complex were compared with those of 14 individuals interred in residential contexts within the city. Results provide new information concerning daily subsistence at Classic period Teotihuacan (ca. A.D. 200–600) and highlight the dietary distinctiveness of individuals interred within the Feathered Serpent Pyramid as compared to the general residential population of the site, particularly in terms of the carbon isotope composition of protein sources consumed by a number of the sacrificial victims. Oxygen isotope analysis suggests that most individuals from the Feathered Serpent Pyramid resided within the local Teotihuacan area during the years immediately prior to their deaths, indicating that the unique dietary pattern seen in stable carbon isotope values cannot be attributed to nonlocal residence prior to sacrifice. Rather, these dietary differences may suggest that the group of individuals selected for interment within the Feathered Serpent Pyramid offering complex maintained a distinctive social or economic identity as compared to the rest of the Teotihuacan population during their lives.
