The iceman as a burial

Since his discovery in 1991 the iceman has been widely seen as meeting a dramatic end – mortally wounded by an arrow shot while attempting to flee through an Alpine pass. A careful study of all the located grave goods, here planned comprehensively for the first time, points strongly towards the scene as one of a ceremonial burial, subsequently dispersed by thawing and gravity. The whole assemblage thus takes on another aspect – not a casual tragedy but a mortuary statement of its day.

The Intangible Weight of Things: Approximate Nominal Weights in Modern Society

Contemporary society is not always based on a strictly quantitative definition of the value of things. Retail trade goods are often sold in “portions” that can bear a nominal round weight, approximately related to their real weight. In fact, these small trade quantities are better understood as customary standards, defined by the convergence of retail offers and customers’ needs. The quantitative properties of portions have been analyzed in order to infer the dynamics of their production and exchange. Some of the properties of portions with a nominal round weight are also shared by portions sold at their exact real weight. A methodological reflection on the concept of portions seems to be appropriate. It is proposed that the ethnoarchaeological study of contemporary portions may also serve as a proxy for better understanding how to analyze the weight distribution of exchangeable materials in pre-literate societies.

Long-lasting ergot lipids as new biomarkers for assessing the presence of cereals and cereal products in archaeological vessels

Cereals were very important in ancient diets, however evidence from archaeological sites of the vessels used for processing or storing cereals is comparatively rare. Micro-organisms, as well as chemical-physical effects can easily degrade cereals during the burial period. This can lead to a complete cereal decay and to serious difficulties in estimating the intensity of use of the cereals by ancient populations. Here, we present a novel biomarker approach entailing the detection of secondary lipid metabolites produced by ergot fungi (genus Claviceps), which are common cereal pests. The aim was to identify the original presence of Gramineae and to indirectly establish if vessels were used for cereal storage/processing. The fatty acid and TAG-estolide profiles of the remains from more than 30 archaeological vessels were investigated by gas chromatography/mass spectrometry (GC/MS) and high performance liquid chromatography/high resolution mass spectrometry (HPLC/ESI-Q-ToF). The detection of lipids derived from ergot in archaeological and historic contexts rests on its complex chemistry, providing a unique and relatively recalcitrant chemical signature for cereals. This research demonstrated that the combination of our innovative biomarker approach along with environmental and archaeological evidence can provide unprecedented insights into the incidence of cereals and related processing activities in ancient societies.

How much is known about glassy materials in Bronze and Iron Age Italy? New data and general overview

Knowledge of glass trading in protohistoric Southern Italy has been limited by a lack of archeometrical data available to date, preventing comparison with the well-known Northern Italian context. The aim of the present work is to help fill the data gap for Southern Bronze-Iron Age vitreous items and enable a general overview of protohistoric Italian glass supply routes. The paper presents physical-chemical data for 61 vitreous items from 11 Southern Italian sites, dated from the beginning of the Bronze Age up to the Archaic period (22nd–6th century BC), ensuring a complete diachronic analysis. SEM-EDS, EMPA, LA-ICPMS, and XRD analyses permitted definition of the raw materials and manufacturing techniques employed, as well as determination of item provenance. The sample set exhibits great variability of glass chemical types, including plant ash glass, mixed alkali, and natron samples. A complex picture emerges, mostly as regards the different natron glass typologies (High-Zr, Low-Zr, Black, etc.) and their rapid technological evolution in the early 1st millennium BC. Taking into account the data reported in this study and those available in literature for both Northern and Southern Italian Bronze-Iron Ages items, this work demonstrates the existence of different trade routes for the first time. This is especially true for the Early/Middle Bronze Age periods, with Northern Italy involved in trade with Central Europe, and South already involved in Mediterranean trade circuits.
