Metallurgia del piombo e siderurgia nel sito protostorico di Brunku ’e s’Omu (Sardegna centro-occidentale): inquadramento funzionale dei manufatti e ricostruzione dei processi produttivi

The archaeological excavations carried out in 2013 in the hut n. 16 of the protohistoric settlement of Brunku ’e s’Omu (central-western Sardinia) returned some metal products. The morpho-metric and functional study of these artifacts al-lowed the identification of two mending strips and other remains related to Bronze Age (late II millennium BC) ceramic vessels reparing. Some uncertainly dated slags and metal fragments were also identified. Visual examination and archaeometric investigation carried out by means of portable energy dispersive X-ray fluores-cence spectrometry (pXRF) were performed on these metals. The analyses were able to relate some remains to iron manufacturing and highlighted the lead composition of the other ones. The chosen approach further clarified some as-pects of nuragic metallurgists’ behaviour in selecting and processing metalliferous geo-materials.

Il «Castellazzo» di Monte Iato in Sicilia occidentale (PA) Quinta e sesta campagna di scavo. Aggiornamenti dal territorio

From May 15th to 30th and 15th to 30th September 2015 took place the fifth and sixth excavation campaign at the Castellazzo of Monte Iato. The presence of 15 participants made it possible to deepen the research significantly and ex-pand the surface area of investigation. It is completely emptied a room already identified in previous campaigns and provided new information about the relationship with the existing cemetery. Part of a burial in a supine position was destroyed by the installation of wall 20. Traces of another turret projecting from the walls have been discovered in the east and another section of the inner walls (15) was fully exposed. A gate, between two towers, is the first entry traced so far, on the north-eastern side of the plateau. The archaeological materials found confirm the characteristics and type of construction. Being a military camp of ephemeral nature, although active at least 30 years, objects such as arrowheads and crossbow quarrels, knives, buckles and harnesses for horses have been found. One of the environments has been interpreted as an area where gaming took place because of the presence of four dice in ivory, glasses and different coins, in addition to the greater extent than the other environments found. Among the findings are reported a glass weight with a cufic inscription dated to the mid-twelfth century and two bronze coins dated in 15th centu-ry.
