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 The essay, through the analysis of unpublished archival sources, outlines the patronage of some members of the Ventimiglia family for Lascari and its parish church from the end of the 17th century to the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…
Spectrophotometric investigations at the museum: monitoring of colour changes during differentiated cleaning of the marble statues
2011
The spectrophotometric investigations carried out during the cleaning treatments on the marble surface provide an useful support for choosing the best method to employ by monitoring, before and after the tests, both the chromatic coordinates and the spectral reflectance. Moreover, the colorimetric measurements allow us to evaluate the goodness of the chromatic level and the uniformity of the cleaned areas. The Laboratory of Physics and Indoor Environment of the Regional Center for Planning and Restoration has carried out the spectrophotometric investigations on the marble statues belonging to the Renaissance statuary collection of the Regional Gallery of Sicily Palazzo Abatellis in Palermo …

First record of an established marbled crayfish Procambarus virginalis (Lyko, 2017) population in Estonia
2019
Invasive marbled crayfish Procambarus virginalis (Lyko, 2017) is spreading alarmingly fast across European countries and beyond. Early maturation, parthenogenetic reproduction mode and high growth rate contribute to a high potential invasiveness. Marbled crayfish can pose severe effects on native communities impacting the native crayfish populations being carrier of the crayfish plague disease caused by Aphanomyces astaci. Here we report the first record of marbled crayfish in Estonia. In total, 104 individuals were found in the artificially warm outflow channel of the cooling system of Balti Power Plant, entering to the water reservoir of the River Narva. Molecular analyses confirmed the m…
First breeding evidence of marbled duck (Marmaronetta angustirostris) in Libya.
2014
4 pages; International audience; The first evidence of breeding of Marbled Duck (Marmaronetta angustirostris) in Libya, North Africa, is reported. In June 2012, at Mallaha wetland, in Tripoli, Libya, two dead ducklings were found that were later genetically identified as Marbled Duck. This breeding evidence suggests that this and other duck species may breed elsewhere in Libya. Better knowledge on Libyan, and more generally on north African, waterbirds is needed to document the population size and the status of these species. Such information will be important to secure the future of threatened species, such as the Marbled Duck.
Architecture, materials and languages. From marble to stone and viceversa (Sicily 15th-16th centuries)
2018
Tra la seconda metà del Quattrocento e i primi decenni del Cinquecento l’architettura in Sicilia offre un caso di coesistenza di due “mondi” legati a tecniche e linguaggi riconducibili ad ambiti culturali differenti: tardogotico e rinascimento secondo le etichette della storiografia tradizionale. Questo contributo propone un approccio non convenzionale che parte da una riflessione su materiali e prerogative professionali dei gruppi portatori delle due differenti culture di progetto, come campo di osservazione per i mutevoli rapporti di forza tra le stesse. Se in un primo momento la pietra è il campo del tardogotico e il marmo bianco quello del classicismo e le due realtà convivono, successi…
