Identification of lead pigments in nanosamples from ancient paintings and polychromed sculptures using voltammetry of nanoparticles/atomic force micr…
2007
Voltammetry of nanoparticles coupled with atomic force microscopy was used to identify lead pigments in nanosamples proceeding from works of art. Upon mechanical attachment of few nanograms of sample to a graphite plate, well-defined voltammetric responses were obtained for lead orange, lead yellow, lead white, litharge, minium, Naples yellow, and tin-lead yellow, allowing for an unambiguous identification of such pigments. Atomic force images provide evidence for the occurrence of pigment-characteristic reduction processes accompanied by metal deposition on the graphite substrate. Electrochemical parameters are used for pigment identification. Application to the method for identifying lead…
Il palazzo di Phestos a Creta: Scavo e restauro
2014
Nel 1900, la Missione Archeologica Italiana di Creta, guidata da Federico Halbherr, con la collaborazione di alcuni archeologi e studenti di archeologia, fra i quali Luigi Pernier, scoprì i resti del palazzo minoico di Festòs, posto a pochi chilometri da Eraklion, capoluogo dell’isola di Creta. Contemporaneamente alla messa in luce dei resti furono eseguiti i primi interventi di restauro e sistemazione, tra questi la pulitura degli interstizi fra i conci lapidei e la stesura di malta cementizia colorata, in modo da intonarla rispetto ai resti, la sistemazione delle parti superiori dei resti murari e la costruzione dei solai in calcestruzzo di cemento armato, un tempo realizzati con struttur…
From Maya Blue to “Maya Yellow”: A Connection between Ancient Nanostructured Materials from the Voltammetry of Microparticles
2011
The yellow hue of a series of samples from wall paintings in several Mayan archaeological sites can be attributed to the presence of indigoid compounds, including isatin and dehydroindigo, attached to palygorskite, a local phyllosilicate clay. SEM/EDX, TEM, UV/Vis spectroscopy, and voltammetry of microparticles show that the ancient Mayas could prepare indigo, Maya Blue, and "Maya Yellow" during successive stages.

Défis communs et objectifs partagés pour les sites archéologiques, entre la Sicile et la Tunisie
2014
Il Progetto APER (Architettura domestica Punica, Ellenistica e Romana: salvaguardia e messa in valore) è stato finanziato dall’Unione Europea nell’ambito della Cooperazione transfrontaliera Italie Tunisie 2007-2013. Le principali motivazioni del Progetto APER: - aver indicato nel patrimonio archeologico una rilevante testimonianza di quanto sia radicata la comune identità degli uomini vissuti attorno al Mediterraneo sin dai tempi più remoti; - aver individuato nell’ellenismo l’età aurea di tale identità comune, - aver preferito porre attenzione sull’architettura domestica, invece che su edifici specialistici; - aver evidenziato la maggiore vulnerabilità dell’architettura domestica, costruit…

Finanziato dall’Unione Europea nell’ambito della cooperazione transfrontaliera Italie Tunisie 2007-2013, il Progetto APER (Architettura domestica punica, ellenistica e romana: salvaguardia e valorizzazione) ha unito istituzioni italiane e tunisine (il capofila Polo Didattico di Agrigento dell’Università di Palermo, con i partner Consorzio Universitario Provincia di Agrigento, Institut National du Patrimoine e Agence de Mise en Valeur du Patrimoine et de Promotion Culturelle e gli enti associati Parco della Valle dei Templi di Agrigento, Provincia Regionale di Agrigento, Centro Regionale per la Progettazione e il Restauro della Regione Siciliana, École Nationale d’Architecture et Urbanisme d…
Historical mining and smelting in the Vosges Mountains (France) recorded in two ombrotrophic peat bogs
2010
Two peat sequences were sampled in the vicinity of the main mining districts of the Vosges Mountains: Sainte-Marie-aux-Mines and Plancher-les-Mines. Lead isotopic compositions and excess lead fluxes were calculated for each of these radiocarbon-dated sequences. Geochemical records are in very good agreement with the mining history of the area, well known over the last millennium. Except for an anomaly corresponding to the Middle Bronze Age which has not yet been resolved, there is no clear geochemical evidence of local metal production in the Vosges before the 10th century as excess lead deposition archived between 500 BC and 500 AD is attributed to long-range transport of polluted particul…
Analytical study by SEM/EDX and metallographic techniques of materials used in the iron production process during the iberian period
2002
Abstract This work is the archaeometric study of different types of materials used in iron production in the Iberian Period (6th–2nd century b.c.). The materials were recovered in several archaeological digs (which makes it possible to date the archaeological remains) on different sites in the Levante area of the Iberian Peninsula. The samples selected for this study belong to different materials used in the ancient iron production process such as ores, slags, finished objects, etc. The use of scanning electron microscopy (SEM) is proposed to observe surface images of the samples to determine their morphological, microstructural and topographic characteristics to obtain valuable information…
THE PETROGRAPHY AND CHEMISTRY OF THIN-WALLED WARE FROM AN HELLENISTIC- ROMAN SITE AT SEGESTA (SICILY)*
2003
Samples of Roman thin-walled ware from Segesta (northwestern Sicily), dating back to the early Imperial period, were studied by optical microscopy (OM) and Neutron Activation Analysis (NAA). Up to now, this class of Roman fine tableware has only occasionally been evaluated archaeometrically. Nevertheless, numerous production centres are believed to have been simultaneously active in the western Mediterranean area. Petrographic and chemical data seem to be in agreement with the archaeological hypothesis of local manufacture in Segesta for most of the analysed samples, through a comparison with kiln wasters and local raw materials. The effectiveness of thin-section petrography for determining…

Social and technological changes in the ceramic production of the Northern Levant during the LBA/IA transition: New evidence about the Sea People iss…
2019
Abstract The transition from the Late Bronze Age (LBA) to the Iron Age (IA) in the Levant is marked by the collapse of the Egyptian and Hittite empires, which dominated the political scene of the 14th–13th century BCE. The role of the Sea People, groups of migrants who were defeated by the Egyptian king Ramses III around 1175 BCE, is the focal point concerning this period. After the collapse of the LBA empires, written sources disappeared, and the archaeologists’ primary tool to define cultural processes is to analyze the evolution of pottery. Because of this, studies about the distribution of Aegeanizing ceramic production, considered here to have derived from the Sea People culture, can p…
