The smelting of copper in the third millennium cal BC Trentino, north-eastern Italy

This paper presents observations and analyses on seven slag pieces from two third-millennium cal BC (Late Copper Age/Early Bronze Age) rock shelters in the Trentino, north-eastern Italy: La Vela di Valbusa and the Riparo di Monte Terlago. We review previous work on contemporary slags from the region and show that the smelting did not follow the well-known ‘Timna’, ‘Eibner’ or so-called ‘Chalcolithic’ copper smelting processes. We show that ethnographic accounts of copper smelting in the Himalayas (Sikkim and Nepal) illuminate the smelting process, in particular the lack of preliminary roasting or ore beneficiation by washing, the use of slags as fluxes for the first smelt (matte smelting) and the use of wooden (?) implements to lift the hot slags from the furnace during the smelt. The rock inclusions in the slag are consistent with an ore origin from mines at Calceranica or Vetriolo, as previously reported in the literature.

Prehistoric human presence on Mount Etna (Sicily), in relation to the geological evolution

This study analyses the relationship between the pre- and protohistoric sites on the slopes of Etna and the volcanic products, as well as the diverse settlement strategies in the different periods of prehistory. New C14 dating from significant excavations, in addition to those known from other Etnean sites, were performed with the aim of validating the chronology of the sequence of the different phases. A substantial concordance of the archaeological data with the volcanological ones has been found. It has been observed that a consistent human presence on Etna appears from the Middle Neolithic (5500 BC), after the sequence of eruptive events that marked the end of the Ellittico volcano (13550 - 13050 BC) and the formation of the Valle del Bove, and the subsequent debris and alluvial events on the eastern flanks of the volcano (7250 - 3350 BC). Human presence intensifies between the Late-Final Copper Age and the Early Bronze Age (2800 - 1450 BC), due to improvement in subsistence techniques and to the large presence of soils on lava flows suitable for sheep farming. The most recent phases of the Bronze Age are poorly represented, probably because of the concentration of the population in larger agglomerations (Montevergine and S. Paolillo at Catania, the Historical Hill at Paternò). The explosive eruptions taking place in this period seem to have had less impact on the settlement choices and have not affected the development of the sites over time.

Multidisciplinary investigation reveals the earliest textiles and cinnabar-coloured cloth in Iberian Peninsula

Textile production is among the most fundamental and more complex technologies in human prehistory, but is under-investigated due to the perishable nature of fibrous materials. Here we report a discovery of five textile fragments from a prehistoric (fourth-third millennium cal BC) burial deposit located in a small cave at Peñacalera in Sierra Morena hills, near Córdoba, Southern Spain. These textiles accompanied a set of human remains as grave goods, together with other organic elements such as fragments of wood and cork, and some pottery vessels. They were characterized and dated using digital microscopy, Scanning Electron Microscopy, Energy Dispersive Spectroscopy and Accelerator Mass Spectrometry. Two of the fragments described here are the oldest examples of loom-woven textiles in the Iberian Peninsula, dating from the second half of the fourth millennium cal BC. This correlates chronologically with the first appearance of loom weights in the archaeological record of this region. The more recently dated textile is the earliest preserved cloth intentionally coloured with cinnabar in the western Mediterranean. The Peñacalera finds are a key reference for understanding the development of textile technologies during the Neolithic and Copper Age in western Europe and beyond.

Kozachyi Yar 1: An enclosed Trypillian settlement on the Southern Bug River in Kozavchyn (Ukraine)

Summary In Kozavchyn on the Southern Bug, an Early Copper Age settlement surrounded by trenches was explored by means of field surveys and magnetic prospection. In addition to the enclosing trenches, the magnetogram revealed a palisade trench and remains of pits and burnt houses, which covered a contiguous area with archaeological findings of almost 4 ha situated on a spur with the field name “Kozachyi Yar”. The settlement belongs to the Trypillia BI local group Sabatynivka, as does the nearby site Kamyane, “Kamyane-Zavallia 1”, also surrounded by ditches, which was investigated a few years ago and dated to the last third of the 5th millennium BC. The Sabatynivka group is documented in a narrowly confined area on both sides of the Southern Bug River and may have once been a jointly acting political entity. Internal conflicts or external threats from the steppe area to the east are often considered as reasons for the enclosure of CTCC settlements. It seems conceivable, however, that the apparently once much more numerous enclosures had less of a protective than merely a delimiting character.

Isotopic evidence for population dynamics in the Central Italian Copper Age and Bronze Age.

The mobility patterns in the Italian peninsula during prehistory are still relatively unknown. The excavation of the Copper Age and Bronze Age deposits in La Sassa cave (Sonnino, Italy) allowed to broaden the knowledge about some local and regional dynamics. We employed a multi-disciplinary approach, including stable (carbon and nitrogen, C and N, respectively) and radiogenic (strontium, Sr) isotopes analyses and the identification of the cultural traits in the material culture to identify mobility patterns that took place in the region. The Sr isotopic analyses on the human bones show that in the Copper Age and at the beginning of the Bronze Age, the cave was used as a burial place by different villages, perhaps spread in a radius of no more than 5 km. Stable isotopes analyses suggest the introduction of C4 plants in the diet of the Middle Bronze Age (MBA) communities in the area. Remarkably, in the same period, the material culture shows increasing influxes coming from the North. This evidence is consistent with the recent genomic findings tracing the arrival of people carrying a Steppe-related ancestry in Central Italy in MBA.
