La ricostruzione tridimensionale e il restauro virtuale di una tomba etrusca dipinta dell’Etruria meridionale interna: la “Grotta Dipinta” di Pranzovico (Viterbo)
No full textEl artículo se refiere a la reconstrucción en 3D y la restauración virtual de algunas tumbas pintadas de cámara excavadas en la roca ubicadas en el interior del sur de Etruria (provincia de Viterbo, Italia central). La tumba fue descubierta en 1901 en un lugar llamado Pranzovico y data de la mitad del siglo V; tiene planta de cruz con el centro del atrio (decorado con pinturas) y tres cámaras en las que se encuentran las camas funerarias excavadas en la roca. Las pinturas fueron en gran parte destruidas por las excavaciones ilegales en los días inmediatamente posteriores al descubrimiento; durante el siglo XX fue dañada a causa de los trabajos agrícolas en los alrededores y ahora está parcialmente colmatada. Su reconstrucción 3D se basa en la escasez de restos que todavía se conservan, el plano y los dibujos de las pinturas hechas en el momento del descubrimiento y la comparación con otras tumbas de Tarquinia y Chiusi

Le Tombe a Tempio di Norchia: dal rilievo all’anastilosi virtuale e alla ricostruzione tridimensionale
No full textLe attività di ricerca presentate in questo contributo sono state essenzialmente finalizzate al rilievo delle facciate delle due tombe presso la necropoli dell’Acqualta e alla documentazione della porzione ovest del frontone della Tomba occidentale (sinistra), conservato al Museo Archeologico Nazionale di Firenze1275. Tali rilievi, effettuati con tecniche indirette, sono stati realizzati, oltre che come basi documentali per lo studio dei due monumenti, anche in funzione della creazione di modelli tridimensionali, che sono stati utilizzati, in particolare, per lo studio ricostruttivo e il restauro virtuale delle facciate rupestri; quest’ultimo si è basato sia sul prospetto bidimensionale che sul rilievo tridimensionale, il quale ha consentito la realizzazione di ipotesi di anastilosi virtuale degli elementi architettonici non in posto della Tomba occidentale (sinistra), ovvero il grande frammento di fregio dorico oggi collocato presso il dromos della camera funeraria e la già ricordata grande porzione del frontone conservata a Firenze. In quest’ottica, il rilievo e la modellazione tridimensionale hanno avuto anche la finalità di contribuire alla documentazione delle raffigurazioni a bassorilievo presenti sulle facciate rupestri, in generale scarsamente conservate (come nel caso dei fregi) o difficilmente raggiungibili (come nel caso dei frontoni), anche con lo scopo di arrivare a proporre una ricostruzione tridimensionale del complesso architettonico
Rilievo e ricostruzione virtuale del Ponte Sud di Hierapolis di Frigia (Turchia)
No full textThe paper concerns the topographical survey and the 3D reconstruction of a Roman bridge-aqueduct located immediately to the south of Hierapolis in Phrygia
(south-western Turkey), along the ancient route directed to Colosse and the internal Anatolia; only its southern abutment and scarce remains of the northern one
are preserved. It is in a very difficult location, inside the narrow and deep valley, and it was never studied before. During the 2011 field work campaign of the
Italian Archaeological Mission, it was surveyed using a high precision differential GPS system (for the plan documentation and its positioning in the digital
archaeological map of Hierapolis) and through a Motorized Robotic Total Station (for the documentation of the elevation and the creation of a 3D model of the
southern side) with the aim of its virtual reconstruction.El artículo se refiere al levantamiento topográfico y la reconstrucción en 3D de un puente-acueducto romano situado inmediatamente al sur de Hierápolis, en Frigia
(suroeste de Turquía), a lo largo del antiguo camino dirigido a Colosas, en el interior de Anatolia. Actualmente sólo se conservan su pilar sur y escasos restos del
pilar norte. Se encuentra en una situación muy difícil, en el interior de un valle estrecho y profundo, y nunca se ha estudiado antes. Durante la campaña de trabajo
de campo de 2011 de la Misión Arqueológica Italiana, fue examinado con un diferencial de alta precisión del sistema GPS (para la documentación del plan y su
posicionamiento en el mapa digital arqueológico de Hierápolis) y a través de una estación total robótica motorizada (para la documentación de la elevación y la
creación de un modelo 3D de la cara sur) con el objetivo de su reconstrucción virtual
Il Teatro Nord e le mura proto-bizantine di Hierapolis di Frigia. Dall'indagine topografica alla ricostruzione 2D e 3D
No full textIl Teatro Nord e la cinta muraria proto-bizantina di Hierapolis di Frigia (Pamukkale, Denizli, Turchia sud-occidentale) sono stati a lungo trascurati dalle attività di ricerca della Missione Archeologica Italiana, concentrata su monumenti meglio conservati e con un apparato architettonico e scultoreo più rilevante. Solo dal 2008 essi sono stati oggetto di indagini sistematiche da parte dei ricercatori del Laboratorio di Topografia Antica, Archeologia e Telerilevamento dell'Istituto per i Beni Archeologici e Monumentali del CNR (Lecce). Lo studio di dettaglio dei resti conservati, realizzato integrando rilievo topografico, prospezioni geofisiche ed indagini geologiche, ha permesso di definirne la cronologia e l'articolazione planimetrica, fino a giungere alla proposta di ricostruzioni 2D e 3D.The North Theater and the Proto-Byzantine city walls of Hierapolis of Phrygia (Pamukkale, Denizli, south-western Turkey) have long been neglected by the research activities of the Italian Archaeological Mission, focused on monuments best preserved and with an architectural and sculptural apparatus most relevant. Only since 2008 have they been the subject of systematic investigations by researchers at the Laboratory of Ancient Topography, Archeology and Remote Sensing of the Institute for Archaeological and Monumental Heritage of the CNR (Lecce). The detailed study of the preserved remains, carried out by integrating topographical relief, geophysical surveys and geological surveys, has allowed us to define the chronology and the planimetric articulation, up to the proposal of 2D and 3D reconstructions
Non-invasive archaeological research in Atella (Sant’Arpino-Campania, Italy). Preliminary results from the 2023 campaign
No full textThis paper aims to share the preliminary results from the non-invasive investigations initiated
in 2023 at the archaeological site of Atella in Sant’Arpino-Caserta led by the Archaeological Digital Mapping
Lab at the University of Naples Federico II. Located about halfway along the road from Capua to Neapolis,
Atella and its surrounding territory lie in the central sector of the Campanian plain—a wide alluvial plain
formed by the rivers Volturno and Clanio, north of Mount Vesuvius and the volcanic caldera of the Campi
Flegrei. Historically renowned for the ‘fabulae Atellanae,’ the site’s overall archaeological topography remains
largely uncharted. The new archaeological project began with a renewed evaluation of remotely sensed data
and included an intensive field survey and geophysical prospection using Ground Penetrating Radar. The
2023 campaign was conducted from June to September in Fondo Guarino-Sant’Arpino, which is believed to
encompass Atella’s central monumental area
Towards an operative use of remote sensing for exploring the past using satellite data: The case study of Hierapolis (Turkey)
No full textThis paper is focused on the presentation and discussion of an object oriented approach, applied to the Hierapolis
(Turkey) site, to automatically detect the subtle features linked to buried archaeological remains. The data processing
is applied twice: (i) first, globally at the whole image and, (ii) second, at the significant subsets identified
by global analysis, in order to refine the previously obtained categorization. Object oriented approaches are usually
based on two main steps: i) first the segmentation, ii) then the classification. Herein, we first performed the
unsupervised classification step and, then, the segmentation. This choice is given by the specificity of archaeological
issue, in particular: (i) the subtle features/targets to be identified are partially or totally unknown and characterized
by a very small spectral separability from the background, and therefore (ii) the discrimination
between archaeological class and substrates likely suffers significant confusion. To cope with these issues, the
first step is based on an unsupervised classification, which provides a first ‘rough’ categorization of pixels; the
second step, based on the segmentation, enables us to extract the geometric shape, and, in turn, to only categorize
as archaeological class those pixels belonging to geometrically (rectangular and linear) shaped clusters. Outputs
from this classification identify rectangular and linear features of archaeological interest whose size suggested
that they may be a farm and some sectors of an aqueduct, respectively. Results from satellite based analysis
were successfully evaluated by georadar and geomagnetic prospection along with field survey. From georadar
and geomagnetic prospection we were able i) to confirm the presence of buried remains and ii) to detail and
characterize these archaeological features at the subsoil level as well as to define the local stratigraphy. From
field surveywe dated the detected buried remains to a period spanning from Imperial Roman to early Byzantine
historical times
The use of geophysical prospections to map ancient hydraulic works: the Triglio underground aqueduct (Apulia, southern Italy)
No full textThis paper presents an integrated analysis using ground-penetrating radar (GPR) and electrical resistivity tomography
(ERT) studies to map the Triglio underground aqueduct that in Roman times supplied fresh water to the ancient town of
Tarentum, modern Taranto, Apulia region, Italy. The study area includes an expansion project of a nearby limestone
quarry where mining activity is related to the production of a steel factory (ILVA). The aim was to develop methods
for detection and mapping of the geometry of the underground aqueduct. Seven GPR reflection profiles were acquired
across and parallel to the hypothesized extent of the aqueduct, while the ERT method was used to understand the
stratigraphy of the area and tie reflections to geological units.
Well-preserved vertical shafts for ventilation and inspection of the ancient underground hydraulic work were investigated
and used as models for GPR exploration. The GPR profiles, interpreted using both the trace amplitude analysis
and the forward modelling, showed reflection features from the main horizontal tunnel of the ancient aqueduct. The
void space within the aqueduct, usually the ceiling–air interface, was discovered and mapped using reflections profiles
both parallel to the linear feature, but also crossing it, and differentiated from similar looking geological features. Copyright
