Viabilità romana in Sicilia. Nuove osservazioni sull'ipotetico percorso della via interna Catania-Agrigento
No full textLo studio della via romana che attraversava la Sicilia interna da Catania ad Agrigento, citata nell’Itinerarium Antonini, è reso arduo dalla quasi totale mancanza di evidenze archeologiche dirette e dalla difficoltà nel riconoscere le stazioni intermedie tra le due città, in quanto legate a toponimi di origine prediale. Il presente contributo è frutto di alcune riflessioni, supportate da un approccio multidisciplinare alla problematica, relative in particolare al tratto di strada che da Catania doveva giungere al sito di Sofiana/Philosophiana.
The study of the Roman road that ran through inland Sicily from Catania to Agrigento, as mentioned in the "Itinerarium Antonini", is made difficult by the almost total lack of direct archaeological evidence and by the complexity of recognizing the intermediate stations between the two cities, as these are related to praedial place names. This paper is the result of some reflections, supported by a multidisciplinary approach to the issue, concerning in particular the part of the road going from Catania to the Sofiana/Philosophiana site
La produzione di ceramica a Philosophiana (Sicilia centrale) nella media età bizantina: Metodi di indagine ed implicazioni economiche
No full textSince 2009, through an international collaboration with Cambridge, Cornell and Messina Universities, the Philosophiana Project has investigated the Roman to medieval topographical, architectural, functional, economic and environmental transformations at the site of Sofiana in central Sicily, only 6 km as the crow flies from the Roman "Villa del Casale" of Piazza Armerina. By means of a global approach integrating field survey, open-area excavation, photogrammetry, archaeometry and bioarchaeology, the project shed light on settlement and economic patterns in a crucial area of the Mediterranean world: central Sicily, that served as the bread-basket of Rome in Late Antiquity, and of the Roman Church in the early Middle Ages. In 2010, some 40 m from the eastern side of the site of Sofiana, a field survey identified an 83th to 9th-century A.D. large craft-working district specialising in ceramic production. The site was covered by an extensive geomagnetic survey in 2011 and was subsequently tested by excavation in 2013. Despite the limited area investigated through excavation, this process enabled us to collect significant datasets that help us understand the precise chronology of the workshop, the technology of ceramic production and the wide range of ceramic repertoires manufactured at the first mid-Byzantine ceramic atelier ever excavated on the island. Combining the archaeological data with ancient pollen, faunal remains, ceramic thin-sections and organic residue analysis applied to a sample of jugs and small locally produced amphorae identified at domestic contexts excavated at the site of Sofiana, we are presenting here a preliminary reconstruction of the economic complexity of our site and the early medieval production strategies (both agricultural and artisanal) that determined the various forms of use of the local cultural landscape. The new picture which has emerged from this research suggests that some concepts, such as economic regression and simplification of the material culture, are inappropriate to describe mid-Byzantine Sicily
Fotomodellazione 3D e rilievo speditivo di scavo: l’esperienza del Philosophiana Project
No full textThe author illustrates the graphic documentation process that has been developed during the excavations at Sofiana in the Municipality of Mazzarino (CL, Sicily), as part of the Philosophiana Project. The project started in 2012 thanks to the cooperation between the Universities of Cornell, Cambridge and Messina and since the beginning it was necessary to document the excavations speedily, but without the loss of measurement accuracy featuring a well-established methodology of archaeological survey. The pipeline of the work has consisted in digitising archaeological contexts in a GIS platform from an orthophoto produced with 3D photomodeling. This process resulted in an optimal documentation according to the project requirements. The author also focuses on the importance of graphic documentation, which should be as important as the excavation process itself. Despite archaeology having a long tradition in the field of archaeological survey, this process is often perceived as a necessity rather than a key research tool. For this reason surveys are not always carried out by a professional figure, causing a lack of homogeneity in the final data
Natural Radioactivity Content and Radon Exhalation Rate Assessment for Building Materials from the Archaeological Park of Tindari, Sicily, Southern Italy: A Case Study
No full textThis paper presents a case study of the natural radioactivity level and radon exhalation in limestone and sandstone rocks from the archaeological park of Tindari, located in Sicily, southern Italy. These rocks were representative of natural stones utilised as building materials in the studied area. The activity concentrations of 226Ra, 232Th, and 40K were assessed using high purity germanium (HPGe) gamma-ray spectrometry. Subsequently, the absorbed gamma dose rate (D), annual effective dose equivalent (AEDE), activity concentration index (ACI), and alpha index (Iα) were quantified to evaluate potential radiological health risks associated with radiation exposure from the analysed rocks. Finally, E-PERM electret ion chamber measurements were conducted to accurately quantify the radon exhalation rate from the investigated samples. The results obtained in this case study provide a foundation for further research into the background radioactivity levels in natural stones employed as building materials

No full textIntegrazioni Tecnologiche e Rilievo Archeologico - Il caso di Tindari
No full textThis work shows the first results of the metric survey, through the integrated
use of a series of methodologies and techniques, of the fortifications of the
city of Tyndaris. The features of these walls make it an interesting example
of military architecture whose chronology is still a vexed question. The size
and location of the structures, partly subject to superfetches that reach the
modern age, together with the uneven condition of their conservation, have
always made difficult to carry out an analytical survey of the monument in its
entirety. The integrated use of a set of topographic survey technologies in a
sample area of the monument has given promising results to date, in view of
completing the relief of all the monument
Pseudo-Placentational Endometrial Hyperplasia in the Bitch: Case Series
No full textCanine pseudo-placentational endometrial hyperplasia differs from the classical form of cystic endometrial hyperplasia for the well-organized tissue architecture resembling the canine placenta. After the discovery, it has been inconstantly reported. The present work reports the clinicopathological details of six spontaneous cases retrieved retrospectively from a large database. The lesion was found in young non-pregnant female dogs (median 2.0 years) at the end of dioestrus. It could be imaged by ultrasound and was always grossly detectable as single or multiple uterine enlargements of 2–3 cm in diameter with a villous whitish tissue growing on the mucosa and occluding the lumen. Histology confirmed the tissue architecture of the canine placenta with a basal glandular layer, a connective band, a spongy layer and a tortuous and compact labyrinth, often poorly recognizable. The pseudo-placentational hyperplasia is a non-inflammatory proliferative lesion although numerous mast cells inhabit the connective band, and a superimposed inflammatory infiltrate was seen in a case. Canine pseudo-placentational endometrial hyperplasia has very peculiar features, and it is a model for canine placentation and may help to better understand the cystic endometrial hyperplasia/pyometra complex
