The site, interpreted as a rural luxury residence dated to the fourth-fifth century CE, was first discovered in 1972 and intermittently investigated in the subsequent decades and mostly studied from the perspectives of the splendid mosaic floors there uncovered. The excavated structure accounts for just a portion of the complex, which is partially covered by an eighteenth-nineteenth century farmhouse. After a long period of neglect, the villa, mainly known in literature for its exquisite mosaic floors, has been recently restored and opened to the public and become subject of new studies by the University of South Florida's Institute for Digital Exploration (IDEx) and the Institute of Heritage Science-CNR which between 2019 and 2022 conducted a remote sensing, using ground penetrating radar method, campaign in partnership with the Parco Archeologico e Paesaggistico di Siracusa, Eloro, Villa del Tellaro e Akrai. The results related to the digital exploration and ground penetrating radar allow new knowledge relating to the Roman villa and allows a scientific reconstruction of the villa.

Despite its historical and economic importance in the Roman and Medieval periods, our knowledge about the organization of its agricultural production, and economic circuit between the rural settlements and the city are limited. From 2009 the researches of the “Institute of Heritage Sciences – CNR” attempt to remedy this omission by outlining a preliminary picture of the rich historical and archaeological heritage of Priolo Gargallo, which will be analysed using a multidisciplinary approach (archaeological survey, geophysical investigations, aerial photography analysis, etc.).

For the first time this research shed light on the territories of Syracuse and Catania, cities for which, despite their important political and economic roles in Roman and medieval Sicily, there is a lack of data for the surrounding countryside. Indeed, the interest in this question derives from the absence of research whose main aim is the understanding of the social-economic role of the city in the Mediterranean during the long transition from the Roman to the medieval period, an investigation that cannot ignore the rural areas closest to the urban centres.

The inherent informative potential of the archaeological/monumental heritage present in the Porta Nocera necropolis poses notable problems for the conservation and restoration of the structures and surfaces of the funerary monuments. Brought to light at different times during the second half of last century, they show signs of degradation caused by atmospheric agents and the rising level of the water table, which threatens the foundations. Other important monuments could be still buried. In order to verify both the state of preservation of the foundations of funerary buildings, the presence of still active causes of deterioration and the probable presence of other buried archaeological structures, integrated geophysical surveys, with ground penetrating radar (GPR), passive (Self Potential—SP) and active electrical resistivity tomography (ERT), were undertaken. Furthermore a three-dimensional model of the entire necropolis was created. This involved the creation of a specific survey methodology, combining laser scanning with ortho-photogrammetry using shots taken on the ground and from the air by the use of a drone. The integration of the acquired data allows us to plan future interventions of restoration.

Starting from the reading of the historical evidence and interpretation of archival records (i.e. aerial photos related to the twenties, thirties and forties years of last century, before the urban transformations between the two World Wars and later, and satellite images of the sixties and recent years) the research proposes to develop targeted investigations with the integrated use of Ground Penetrating Radar (GPR) method and image processing techniques of contemporary photographs in order to locate a late Roman villa. All the information provided by aerial and GPR analysis as well as literature references constituted the basis for attempting a virtual reconstruction of the lost Roman's villa in order to give the visual idea of how it probably was. Accordingly to London and Seville Charter principles, different levels of reliability in data interpretation have been identified and characterized aiming at making transparent the methodological choices and the accuracy of reconstruction undertaken.

Nevertheless, the socio-economic aspects of its territorial management and the relation between the countryside and coastal centres in the complex system of the Mediterranean markets have not yet been analysed in depth by scholars. Despite the historical, monumental and economic importance of the surrounding area of Syracuse in the Antiquity, the knowledge of the roman and medieval landscape and archaeological sites are still limited. The research undertaken by Istituto per i Beni Archeologici e Monumentali - CNR of Catania (Sicily, Italy) attempted to remedy this omission by outlining a preliminary picture of the rich historical and archaeological heritage of Syracuse and its surrounding territory, which will be analysed using a multidisciplinary approach. Augusta, a town near Syracuse (Sicily), was founded by emperor Frederick of Suavia between 1232 and 1239. In medieval period, the area of Giardini Pubblici was the downtown and untill the XVII Cent. AD it was occupied by two urban blocks of buildings. In 1670 they were demolished to allow free area firing line from the near castle. Integrated archaeological and geophysical investigations allowed a wide range knowledge of the roman and medieval landscapes, archaeological sites and monumental remains. Particularly the geophysical surveys undertaken in the historical center of Augusta, by means Ground-penetrating Radar (GPR), allowed a 3D reconstruction of archaeological structures in the subsoil until the depth of about 4m. The geophysical survey has identified the building of medieval and modern urban settlement of Augusta and has allowed to recreate the urban plan and its transformation.

The scientific rigour and precision of the traditional instrumental mapping together with the use of new technologies and geophysical methods have produced high-definition 3D models of the funerary monuments and necropolis as tools to store and manage scientific information.

Voluto dall’intelligenza documentaria di Fiorelli ma realizzato dalla perizia di più mani e in un ampio arco storico, si pone emblematicamente in un momento di transizione: dalla camera lucida, dal disegno quadrettato, dall’acquarello dei quadri figurativi e delle decorazioni parietali, alla fotografia. Mentre si modellava il plastico con sughero, stucco e pennello, a Pompei l’architetto Normand eseguiva i suoi primi calotipi.
Oggi, sulla scia della campagna di rilevamento fotografico di Pompei curata dall’ICCD anni or sono, l’intero Plastico di Pompei è stato acquisito mediante fotografia digitale e restituito tridimensionalmente: dall’archivio materico ad un archivio digitale 3D. All’incrocio tra fotografia d’archivio e nuove metodologie, il suo rilievo costituisce un archivio singolare di immagini e informazioni correlate nello spazio e mediate a loro volta dal modello analogico in sughero: un efficace strumento di ricerca, conoscenza e divulgazione nell’era degli open data. Considerando alcune domus pompeiane e le loro decorazioni parietali, è possibile operare con più efficacia un confronto fra il loro stato attuale di conservazione, il corpus fotografico d’archivio in merito a quei contesti e la testimonianza del plastico mediata dal suo modello 3D.

Eppure, prima di inoltrarsi in una preliminare ricostruzione delle fasi di realizzazione del grande modello pompeiano, occorrerà tentare di iscrivere quest’ultimo nella sua complessa tradizione, nel background culturale da cui scaturisce e da cui si allontana, cercando inoltre di valutarne le motivazioni sottese e, in quanto riproduzione, i suoi rapporti con l’originale. Obiettivo del progetto è quello di utilizzare la tecnologia di documentazione 3D come uno strumento privilegiato per mettere in evidenza le straordinarie potenzialità documentarie del plastico, ricreando un modello tridimensionale tale da consentire la fruizione, lo studio analitico e una percezione potenziata delle strutture riprodotte, con la possibilità, per l’utente/fruitore, di potersi muovere liberamente all’interno di uno spazio virtuale, ma esattamente e rigorosamente riprodotto. Attraverso tale modello sarà, ad esempio, possibile, registrare, a livello autoptico, le analogie e le differenze con lo stato attuale degli ambienti pompeiani in esso riprodotti.

Con la medesima carica propositiva e originalità del progetto di Valorizzazione dell’Anfiteatro romano di Catania portato avanti dall’Istituto per i Beni Archeologici e Monumentali del Consiglio Nazionale delle Ricerche, da cui prende spunto, la presente guida rende conto non solo dei risultati delle più recenti indagini scientifiche condotte dall’IBAM-CNR nell’anfiteatro, ma anche dei racconti e delle curiosità nate intorno ad esso. Perché è solo con la conoscenza che la riconquista fisica di uno spazio può tramutarsi in ben più duraturo acquisto culturale.

Quale tipo di comunicazione attiviamo quando osserviamo un oggetto musealizzato, apparentemente senza contesto? E quali dati sensoriali accendono questa comunicazione?La percezione visiva è solo una delle forme, certo la più comune, attraverso cui avviene la comunicazione tra noi e gli oggetti, ma le informazioni diverse che ciascuno di noi ricava da questa esperienza sensoriale sono alla base di ogni personale rapporto cognitivo, tanto più ricco quanto più ricca è la conoscenza del sistema informativo che sta dietro ad ogni oggetto musealizzato. Ma perché una conoscenza avvenga occorre innanzitutto un incontro e spesso gli incontri più emozionanti sono fatti di silenzi, di semplici "sguardi". Sono questi sguardi, a volte mediati come in questo caso dall'obiettivo fotografico, a permettere agli oggetti di "esistere", specialmente quando essi si trovano chiusi nei depositi dei musei.

Il suo obiettivo è la creazione di uno strumento capace di accrescere, attraverso la libera condivisione dei dati, frutto della secolare attività di ricerca storico-topografica condotta in area urbana, la conoscenza collettiva, favorendo la pianificazione e la tutela territoriale. Il presente volume, primo di una serie monografica destinata ad approfondire ogni singolo aspetto della storia e della cultura di Catania, divulgandone i risultati raggiunti, è dedicato all’inquadramento del tema nell’ambito delle ricerche di archeologia urbana, al ruolo della ricerca fatta “nella città e per la città” per giungere all’analisi delle caratteristiche e delle scelte metodologiche operate nella creazione
della banca dati, della piattaforma GIS e del WebGIS, i tre elementi a cui è demandato il compito di archiviare, gestire, analizzare e rendere liberamente accessibili, su base geospaziale, i dati relativi alla complessa stratificazione urbana della città di Catania.
