Spectroscopic analysis used to uncover the original paint colour of the Helsinki Government Palace tower clock faces
2016
The paint stratigraphy of the two clock faces from the tower clock of the Government Palace in Helsinki (Finland) was analysed in order to determine their original colour before restoration works. Paint cross-section samples from both clock faces were analysed by confocal Raman microscopy and scanning electron microscopy coupled to an energy dispersive X-ray spectrometer (SEM-EDS). The results revealed the complex superimposition of paint layers applied over the original black colour. FTIR/ATR analyses proved that the original paint was prepared with linseed oil-resin media. Most likely not all of the different layer colours were visible. Some of the layers were likely to have been a primer…

Life after death: a physicochemical study of materials used by the ancient Maya in human bone ointments
2021
Ancient Maya believed in life after death. They used to prepare dead bodies during burial ceremonies whose purpose was to celebrate the dead and to help them passing through the way from earthly life to the beyond one. Bodies preparation included coloured scented body ointment application, with a deep symbolic connotation and probably also a conservative purpose. The aim of this research was to characterize pigments and binders used by ancient Maya in the preparation of body oint ments used to paint human bones. Emblematic painted bone samples from Xcambó (Maya archaeological site located in the municipality of Dzemul, in the Mexican state of Yucatán) were investigated through a non-destruc…
Investigation on four centuripe vases (late 3rd-2nd cent. B.C.) by portable X-ray fluorescence and total reflectance-FTIR
2021
Abstract Four Centuripe vases dated back to the late 3rd-2nd centuries B.C. were analysed using imaging under visible and ultra-violet illumination as well as complementary non-invasive and non-destructive portable X-Ray Fluorescence (XRF) and Total Reflectance – Fourier Transform InfraRed (TR-FTIR) spectroscopies. The vases are of great importance since they represent a rare expression of the Hellenistic vase painting. Four specimens, a “pyxis”, a “lebes gamikos” and two “lekanides” decorated with figures of different type, are exhibited in the Antonino Salinas Archaeological Museum in Palermo-Italy. The investigation was aimed to identify the used pigments and the painting technique, to r…
Non-Invasive Investigation of Pigments of Wall Painting in S. Maria Delle Palate di Tusa (Messina, Italy)
2019
The characterization of materials used in the archaeological field needs an experimental approach in order to avoid the destruction or perturbation of artworks. In order to afford this purpose, a multi-analytical spectroscopic approach is regularly used. We combined non-invasive analysis by using handheld spectroscopic instrumentations (mainly XRF and Raman spectrometers) in order to characterize the wall painting preserved in the church of S. Maria delle Palate at Halaesa Arconidea archeological site (Tusa, Messina, Italy). The aim of the work is the characterization of the nature of pigments used for the realization of the wall painting. The wall painting, probably representing St. Franci…
Forme e significati dell'architettura nei dipinti, tra Xv e XVIII secolo
2012
I legami e le interazioni tra pittura e architettura hanno origini antiche e propongono durante tutta l’età moderna una immensa casistica di occasioni e momenti di confronto dialettico tra le due arti. Una delle vie di questo dialogo passa per la rappresentazione pittorica di soggetti architettonici. La gamma delle modalità e delle scale di raffigurazione dell’architettura nei dipinti è molto ampia,. Si passa cioè da rappresentazioni nelle quali le immagini architettoniche, siano esse di interni o di esterni, entrano nella finzione pittorica per contestualizzare un racconto, al loro assurgere a protagoniste della scena, sotto diverse forme e con diversi gradi di approfondimento, caricate no…
La Prima Guerra Mondiale nella cultura figurativa siciliana
2019
Nel volume "Dalla memoria del sacrificio alla celebrazione della Vittoria. La Prima Guerra Mondiale nella cultura artistica e architettonica siciliana", il contributo presenta una ricognizione sulla cultura figurativa in Sicilia durante la Prima Guerra Mondiale. Particolarmente interessante l'esame della ricezione artistica del primo conflitto mondiale che si manifestava da una lato nella celebrazione delle personalità eroiche che contribuirono alla vittoria dall'altro nell'interpretazione dei risvolti drammatici, collettivi e individuali, della guerra. L'indagine si concentra su un campione di dipinti, sculture e monumenti con particolare riferimento alla produzione di Mario Rutelli, Domen…
Inferences of dietary preferences of Miocene squirrels (Xerinae, Sciuridae) from the Iberian Peninsula and Namibia using microwear analyses and ename…
2020
In this work, we compared microwear features and enamel thickness from upper molars (M1 and M2) of extinct Xerinae squirrels from the Miocene of Namibia (Vulcanisciurus sp) and the Iberian Peninsula (Atlantoxerus nov. sp. and Heteroxerus rubricati). We also examined the microwear from young and adult specimens of one extant squirrel, Atlantoxerus getulus, to compare it with the extinct species. Both, the microwear features and enamel thickness showed that the Miocene African species presented a more abrasive diet than the Iberian ones.
Multi-sensory approaches to (audio) describing the visual arts
2012
Making art accessible to blind patrons requires the ability to convey explicit and implicit visual messages through non-visual forms. Audio description is often seen as the best way to offer visual texts to blind people; however, one may query whether words alone are sufficient to convey the subtleties of art and to transport the emotional charge such works offer. It is a fact that the dialogue between words and touch may allow these particular “readers” to “see” art in its tangible forms, but perhaps more is needed if one is to give them the opportunity to live the art experience to the full. This article discusses different multi-sensory approaches to making art available to visually impa…
Chemical composition of modern and fossil hippopotamid teeth and implications for paleoenvironmental reconstructions and enamel formation – Part 2: A…
2012
Abstract. For reconstructing environmental change in terrestrial realms the geochemistry of fossil bioapatite in bones and teeth is among the most promising applications. This study demonstrates that alkaline earth elements in enamel of Hippopotamids, in particular Ba and Sr are tracers for water provenance and hydrochemistry. The studied specimens are molar teeth from Hippopotamids found in modern and fossil lacustrine settings of the Western Branch of the East African Rift system (Lake Kikorongo, Lake Albert, and Lake Malawi) and from modern fluvial environments of the Nile River. Concentrations in enamel vary by ca. two orders of magnitude for Ba (120–9336 μg g−1) as well as for Sr (9–21…
