Polished stone axes in the Caput Adriae from Neolithic to Copper Age
No full textThis paper reports the results of a long-term project on the stone axes from Caput
Adriae. Available data show that jade axes originating in the western Alps reached
the Neolithic groups of Friuli Venezia Giulia and coastal Istria as early as the second
half of the 6th millennium BC, during the Danilo/Vlaška culture. The exchange
of this and other classes of lithic artefacts testifies that in this period this area was
fully integrated into long-distance exchange systems that used mainly coastal routes.
These systems would have continued in the 5th millennium BC, as indicated by a
few oversized jade axe blades and other materials. Far from the coast, jade axes
entered central Slovenia, probably reaching sites of the Sava Group of the Lengyel
culture in the first half of the 5th millennium BC. In roughly the same period, shafthole
axes made of Bohemian metabasites (BM) spread over central and southeastern
Europe, crossed the Alps and reached Italy. According to different Neolithic traditions,
during the 5th millennium BC Europe appears to be divided into a jade-using
western area and a central-eastern BM-using one. During the 4th millennium BC,
the exchange networks of Caput Adriae are increasingly influenced by the eastern
Alpine and Balkan world, where the raw material sources of the main groups of
shaft-hole axes are located. The association of the rocks used for axe production and
copper ore suggests that the changes in raw material exploitation strategies during
the Copper Age were probably related to the development of the first metallurgy
Rinvenimenti preistorici di superficie nell’area del Monte Stena in Val Rosandra (Carso Triestino)
No full textVengono descritti i materiali litici (45 manufatti, tra cui 9 strumenti) rinvenuti in superficie nei presso del Monte Stena nel Carso Triestino, distribuiti in due aree di dispersione distanti tra loro poche centinaia di metri.
Le materie prime derivano in gran parte da piccoli ciottoli di origine fluviale provenienti con tutta probabilità dalla valle del fiume Timavo/Reka (Slovenia), mentre non è documentato l’utilizzo della selce del Carso (affiorante soprattutto nell’area di Komen e nella dolina denominata Velike Nive, nei pressi di Aurisina).
Tra i reperti più interessanti, vengono segnalati alcuni strumenti mesolitici che testimoniano una frequentazione della zona, forse per motivi connessi all’attività venatoria, almeno a partire da questo periodo.
Alcuni manufatti frammentari o di difficile interpretazione cronologica sono con tutta probabilità attribuibili a momenti diversi della preistoria

Rediscovering the Lost Roman Landscape in the Southern Trieste Karst (North-Eastern Italy): Road Network, Land Divisions, Rural Buildings and New Hints on the Avesica Road Station
Full text linkAn interdisciplinary study of the ancient landscape of the Trieste Karst (north-eastern Italy) is presented in this paper. Airborne Laser Scanning (ALS) has been applied to obtain high-resolution topography of the 25 km2 investigated area in order to identify potential archaeological anomalies. The ALS-derived high-resolution Digital Terrain Models have been visualized and managed using QGIS and Relief Visualization Toolbox. Possible archaeological anomalies have been verified through field surveys and interpreted using a multidisciplinary approach mainly based on the collection of associated archaeological materials and geomorphological and stratigraphic evidence. From a methodological perspective, the elaboration and study of ALS-derived images, and in particular the local relief model visualization, combined with the collection of Roman shoe hobnails, have proven to be effective approaches for the certain identification and dating of Roman roads in karst environments. The obtained results have revealed an almost completely unknown Roman landscape: the investigated area was crossed by important public roads, whose layout has been accurately reconstructed for a total length of over 10 km, and occupied by large country estates, sometimes enclosed within boundary walls perfectly fitting the Roman land division grid. One of the identified buildings could correspond to a road station, perhaps the Avesica known from ancient itinerary documents—i.e., the itinerarium Antonini Augusti—due to its position and proximity to a major road junction
