L'intonaco Li Vigni nell'architettura del XX secolo a Palermo. Nuove conoscenze e applicazioni diagnostiche per la manutenzione
2013
Il saggio presenta lo studio degli intonaci formulati per imitare le pietre e i marmi naturali che si diffondono in Sicilia all’inizio del XX secolo ed evidenzia che le prime applicazioni e la diffusione delle nuove malte, anche nel resto dell’Italia, risentono delle sperimentazioni condotte in tutta l’Europa. Il contributo riassume i risultati di una rigorosa e capillare ricognizione tra i brevetti conservati presso l’Archivio Centrale dello Stato a Roma inerenti alle malte per il confezionamento dell’intonaco a “finta pietra”, ne analizza i contenuti in modo critico e pone in risalto i contatti culturali con le sperimentazioni dei materiali in atto nell’ambito dei grandi cantieri di resta…
A multi-analytical approach for the characterization of black crusts on the facade of an historical cathedral
2020
Abstract This study focuses on the characterization of black crusts collected from the Monza cathedral located in the homonymous city (N Italy), a hot spot from the point of view of the atmospheric pollution. Black crusts and substrate marble specimens were analyzed by a multi-analytical approach including X-ray Diffraction (XRD), Fourier Transform-Infrared spectroscopy (FT-IR), Stereomicroscopy (SM), Polarized Light Microscopy (PLM), High Resolution Scanning Electron Microscopy coupled with Energy Dispersive X-ray spectroscopy (HRSEM-EDX) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP/MS). The characterization of the carbon fraction (organic carbon, OC, and element…
I Ventimiglia e le arti decorative a Lascari
2016
Il saggio, attraverso l'analisi di inedite fonti archivistiche, delinea la committenza di alcuni membri della famiglia Ventimiglia per Lascari e la sua chiesa parrocchiale dalla fine del XVII secolo ai primi decenni del XIX. Gli esponenti della nobile stirpe per la realizzazione di tali opere, alcune delle quali ancora custodite, si rivolgevano perlopiù ad artisti palermitani, tra cui l'abile marmorario Domenico Magri. The essay, through the analysis of unpublished archival sources, outlines the patronage of some members of the Ventimiglia family for Lascari and its parish church from the end of the 17th century to the first decades of the 19th century. The exponents of the noble lineage fo…
Gilding and pigments of Renaissance marble of Abatellis Palace: non-invasive investigation by XRF spectrometry
2013
Most of the artworks constituting the collection of Renaissance statuary of Abatellis Palace in Palermo (Sicily) show evidence of colour layers and fragments of gold foil that probably once covered the whole marble surface. The restoration of some of these statues has allowed to carry out archaeometric studies about the painting technique and to highlight the original materials and inclusion present on the precious marbles by two famous Italian sculptors of the Renaissance, Francesco Laurana and Antonello Gagini. The measurements have been performed in situ through the integrated use of two non-invasive techniques: visible fluorescence stimulated by ultraviolet light and X-ray fluorescence.…

I due inediti busti reliquiari d’argento del Tesoro di San Mauro Castelverde (Pa). Don Vincenzo Greco e la circolazione delle reliquie dopo il Concil…
2022
Si esamina la diffusione e la circolazione delle reliquie da Roma alla Sicilia e la conseguente proliferazione, a seguito dei dettami del Concilio di Trento recepiti dai vari Sinodi diocesani, di sacre custodie in metallo prezioso o in legno. Vengono, infatti, indagati alcuni reliquiari d’argento che, custoditi nei Tesori siciliani, sono contestualizzati nella pertinente temperie storico-culturale. Due di essi, inediti e dalla tipologia a busto, sono conservati nel Tesoro della Matrice di San Mauro Castelverde (Pa). Della suppellettile liturgica contenente le sacra vestigia di S. Vittoria, sono stati individuati autore e committenti. L’altra inedita opera, voluta dal marchese Simone I Venti…
Environmental performance of building materials: life cycle assessment of a typical Sicilian marble
2009
Background, aim, and scope: The building sector is strategically important for achieving sustainability. Therefore, the improvement of energy and environmental performances are relevant targets because precious building materials such as marble have a significant impact on the environment. The aim of this paper is an analysis of a typical Sicilian marble (Perlato di Sicilia) to evaluate its energy and environmental performance. Marble plays an important role in the economy of Italy and has a global market share of 58% in terms of exports. For the main production areas of marble, relevant environmental performance data are missing except for one region (Tuscany-Massa e Carrara province). Per…

Italica (Seville, Spain): use of local marble in Augustan age
2010
This study concerns 51 marble finds made of “Cipollino verde” coming from the ancient city of Italica (north of the modern city of Santiponce, 9 km NW of Seville, Spain), the earliest Roman settlement in Spain, founded in 206 B.C. The aim of this work was to determine their provenance from Greek and Italian quarries or from local quarries worked in the Iberian Peninsula. Thin-section optical microscopy, X-ray powder diffraction, bulk rock chemistry and O, C and Sr stable isotope analyses were carried out. Results were compared with literature data on “Cipollino verde” marbles quarried in southern Euboea (Greece), Apuan Alps (Italy), Almería, Extremoz, Seville (Spain) and Évora (Portugal). T…
