Geographic film as public research: re-visualizing/vitalizing a terraced landscape in the Italian Alps (Piccola terra/Small land, 2012)

This article describes an experience of geographic filmmaking carried out within a long-term research process (2000–2012) involving the terraced landscape of the Brenta Valley in the Italian Alps. The documentary Piccola terra [Small land] (2012) was co-produced by geographers and professional directors. Engaging in the recent debate on filmic geographies, the aim of this article is to discuss and show what makes a film ‘geographic’. The geographer authored a filmic interpretation of landscape which is spatially and temporally complex, open and mobile, anchored to material features and to personal stories and socio-economic contexts. Produced to support a campaign for the adoption of abandoned terraces by ‘new farmers’, the documentary Piccola terra serves as a means to engage society and produce landscape change. Geographic filmmaking as an action-, public- and social-oriented activity is discussed with reference to the so-called ‘impact agenda’. We propose a style of active engagement through filmmaking which is workable, rather than critical. In order to avoid purely auto-reflective, auto-referential academic speculation on doing filmic and public geographies, this paper, which ideally is read along with viewing of the documentary, materially enters the researched/filmed landscape, developing into a supplementary tool for the international dissemination of Piccola terra.     

Rock art survey in the ancient oasis of Salūt (northern Sultanate of Oman): a variegated iconographic record

The systematic survey of petroglyphs in the area of the ancient oasis of Salūt, in central Oman, highlighted a rich repertoire of representations that are here discussed against the background of Arabian rock art in general. The region displays an extremely rich number of engravings along the slopes of the Jabal Hammah, north of the main site of Salūt. The majority of the petroglyphs find abundant fitting comparisons in the region. The notable exception of the motif of the “man with halberd” is presented, as it appears to be significantly rare and underlines interpretative issues concerning the so-called T-shaped signs, ubiquitous in Arabian rock art. One of its occurrences was radiocarbon dated to before the mid-first millennium BCE. This and other, relative hints for reconstructing the chronological context of the petroglyphs are discussed, indicating that engravings can be broadly dated from the second millennium BCE onwards.     

Multivariable analysis of an Italian Late Neolithic archaeofauna

Reported are the results of a multivariate analysis, here called multivariable analysis, of an Italian Late Neolithic archaeofauna. The technique adopted is that proposed by Behrensmeyer (1991), adapted to the needs of zooarchaeology. It is tested on an inter-hut bone accumulation from the target site of Offida, near Ascoli Piceno, Marche region, in central eastern Italy, which is characterized by vertebrate remains, invertebrates, stone implements, and ceramics. The typology of the ceramics date the site from 3800 to 3100 B.C. Offida's subset was chosen not only for its rich and varied information, but also for its containing both domestic and wild mammalian remains. The multivariable method is tested on these two faunal components both separately and jointly, with the addition of the undetermined specimens. The results are then compared with those obtained plotting the variables of the bone accumulations of two open-air Neolithic settlements, a small, temporary one in Italy, Mulino Sant'Antonio, and a large one in Israel, Hefzibah 7–18. The first is an Italian Neolithic site typologically and dimensionally similar to Offida; the second is outside Italy and much larger than Offida. Offida's domestic assemblage results more fragmented than its wild animal component. It shows evidence of intense elaboration by the villagers, low richness and a relatively higher amount of sheep/goats and cattle, no bone articulation or sorting, as well as the effects of moderate exposure and prolonged trampling. The wild animal component, in contrast, shows rather high equitability and a lower overall body size. The analysis proves that wildlife already was a minor resource for the Late Neolithic people in this part of Italy. The multivariable approach also shows that a backyard or pathway assemblage such as Offida's is more similar to the overall bone accumulation of a small-sized, temporary settlement than to that of a larger site, and that this particular kind of assemblage is characterized both by a patchy distribution of the bone fragments and by a relatively high incidence of trampling.     

Florence baptistery: chemical and mineralogical investigation of glass mosaic tesserae

A recent restoration of the mosaics of the Baptistery in Florence enabled the collection and analysis of a group of glass tesserae. Twenty-three tesserae, dated between the end of the 13th century and the first half of the 14th century, showing different colors were sampled and analyzed to identify the raw materials, colorants and opacifiers employed in their production.     

Warriors from the East. Skeletal evidence of warfare from a Lombard-Avar cemetery in Central Italy (Campochiaro,Molise, 6th–8th Century AD)

The early mediaeval cemetery of Campochiaro is located in Molise (Central Italy) and dates to the 6th–8th centuries AD. It consists of two inhumation areas: one at Morrione and the other at Vicenne. This site is important because of the contemporary presence of locals, Lombards and Avars of the steppes. Campochiaro was probably an outpost against the Byzantine army settled in southern Italy. Since no signs of a stable settlement or built-up area have been found, it seems the cemetery can be attributed to a semi-nomadic group. Many graves contained a man and his horse with the harness complex and typical Avar stirrups. The military nature of this settlement is shown by ostearchaeological evidence of warfare and violence on three skeletal individuals: n. 20, n. 102 and n. 108. Two of them exhibit lesions of the cranial vault probably produced by shock weapons in the fashion of the Byzantine armies: a spiked mace and a battle-axe. The cicatrisation of the wounds and the bony neo-formation suggest that the individuals survived these injuries for a long time. The third individual suffered from leprosy. He shows a long perpendicular cut in the left section of the frontal bone. The wound is clean and, because it is without traces of bony neo-formation, was probably a peri-mortem blow landed with a sharp weapon. The wound was not mortal, because it was very slight and probably produced only a slash. As ritual or magical practises and/or damage produced during the excavation or by the action of roots in the earth can be excluded, this individual was perhaps really a leper warrior who died in combat.     

Susceptibility measurements,optical and X-ray analysis to explain the origin of archaeological magnetic anomalies in Tavoliere lowland (Southern Italy)

Since 2002 a non-invasive investigation integrating aerial photography and high-resolution magnetometry has been carried out for reconstructing extensive ancient settlements in Tavoliere lowland (Southern Italy). Relevant magnetic anomalies were detected in all the surveyed sites allowing a precise mapping of the buried structures over more than 150 ha. Next to this research susceptibility measurements, PXRD, XRF and optical analysis were also performed in order to explain the origin of the notable magnetization contrast between the anthropogenic structures and the embedding materials, generating the measured signals. This last study was accomplished, in 2006, in Monte S. Vincenzo site, a vast Neolithic village where the remotely sensed data were also used to guide some direct inspection. Trial archaeological excavations brought to light parts of C-shaped compounds, providing complete information on the geometry and location of the sources of magnetic signals. Profiting by the archaeological feedback, the susceptibility contrast between the soil filling the ditches and the calcareous substratum was assessed in situ. A synthetic model based on this information was created and compared with the experimental data. The infilling material was also sampled for laboratory analysis: the presence of several magnetic minerals (pyroxenes, monometric magnetite, haematite) was ascertained. Furthermore optical analyses showed different types of volcanic and igneous products such as pumices, melanite garnets and lava fragments. Geomorphological and archaeometric evidence allowed us to relate these materials to activity of the Mt. Vesuvius volcano. Eventually their possible spatial distribution was inferred from recent studies on ash transportation and deposition during explosive activity.     

Microscope observations and DNA analysis of wine residues from Roman amphorae found in Ukraine and from bottles of recent Tuscan wines

Morphological analysis by light and electron microscopy was conducted on wine residues from second century Roman amphorae found in Myrmekion (Ukraine). The results of the archaeological samples were compared with residues formed in bottles of wine from Tuscan vineyards, corked between 1969 and 1977 without filtration and enzyme or biochemical processing. Staining and histochemical observation of the archaeological and recent residues detected nucleic acids. Molecular analysis was also performed using nuclear microsatellite SSRs markers having high polymorphism to study genetic relationships. Genotype profiles of archaeological and recent residues were compared with contemporary cultivars in a data bank. Low homology of genotype profiles of all residues, and oral evidence, confirmed the presence of autochthonous varieties in recent wines and enabled indirect assessment of varieties detected in the archaeological material. The results confirmed that the archaeological material could be related to Sangiovese and indicated Roman wine trade as far afield as Ukraine, whereas the recent residues provided evidence of disappearing native Tuscany cultivars like Gorgottesco, Mammolo, Verdello, Rossone and Tenerone, used for table wines until the late seventies.
