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 Casina cinese alla Favorita di Palermo: un'ipotesi di lettura.
2016
L'articolo verte su un'ipotesi interpretativa della componente decorativa della Casina cinese alla Favorita di Palermo basata sulla componente "alla cinese" e su una sua densa natura confuciana. The paper offers a hypothesis of interpretation of the decorative patterns of the Casina cinese at the Favorita Park in Palermo which is based on the component "in Chinese style" that is characterized by a strong Confucian element.
Suppression of pigment interference in the gas chromatographic analysis of proteinaceous binding media in paintings with EDTA.
2004
A method to suppress the interference of pigments in the analysis of proteinaceous media used in paintings is presented in this paper. This method is based on the formation of metallic ion-ethylenediaminetetraacetic acid (EDTA) complexes previous to the derivatisation process, using ethyl chloroformate (ECF), to transform the amino acids in N(O,S)-ethoxycarbonyl (EOC) ethyl esters. Test specimens, containing different proteinaceous media such as albumin, porcine gelatine and casein mixed with lead white, chalk, verdigris and raw Sienna have been prepared for carrying out this study. Different pH conditions have been probed for the different pigments studied. Values of peak area ratio of ami…
Identification of diterpenes in canvas painting varnishes by gas chromatography-mass spectrometry with combined derivatisation.
2004
A derivatisation method that combines the formation of ethyl esters from the carboxylic groups and trimethylsilyl ethers from hydroxyl groups of the components of diterpenic resins is presented in this paper. This methodology involves two experimental steps: (1) formation of ethyl esters using ethyl chloroformate; and (2) the esterified compounds are lead to react with trimethylsilylimidazole to form the corresponding trimethylsilyl ethers. The main advantage of the proposed method is the possibility of performing simultaneously the analysis of amino acids from proteins, fatty acids from drying oils, and diterpenic compounds from natural resins usually found in works of art. This methodolog…
Il nobile casato dei Ventimiglia e Donna Felice Ventimiglia Barberini
2017
Nella prima parte del saggio (R.F. Margiotta, Il nobile casato dei Ventimiglia dalla Liguria alla Sicilia) si delinea la storia dei Ventimiglia, provenienti dalla Liguria, insediatisi in Sicilia sin dal Duecento, da Francesco I a Francesco IV Rodrigo, padre di Felice Ventimiglia, e ci si sofferma sulle opere più rappresentative da loro commissionate. Nella seconda parte (M.C. Di Natale, Felice Ventimiglia Barberini dal principato di Castelbuono a Roma) si prende in esame la figura di donna Felice Ventimiglia e se ne ripercorrono le vicende della vita attraverso due significativi documenti: l'inventario dotale della nobildonna, stilato nel 1693, in occasione delle nozze con il principe di pa…
Attentional vs computational complexity measures in observing paintings
2009
Because of the great heterogeneity of subjects and styles, esthetic perception delineates a special and elusive field of research in vision, which represents an interesting challenge for cognitive science tools. With specific regard to the role of visual complexity, in this paper we present an experiment aimed to measure this dimension in a heterogeneous set of paintings. We compared perceived time complexity measures - based on a temporal estimation paradigm - with physical and statistical properties of the paintings, obtaining a strong correlation between psychological and computational results.
Impact of biocide treatments on the bacterial communities of the Lascaux Cave.
2009
The Lascaux Cave contains a remarkable set of paintings from the Upper Palaeolithic. Shortly after discovery in 1940, the cave was modified for public viewing and, in 2001, was invaded by a Fusarium solani species complex. Benzalkonium chloride was used from 2001 to 2004 to eliminate the fungal outbreak. In this study, we carried out a sampling in most of the cave halls and galleries. Sequence analysis and isolation methods detected that the most abundant genera of bacteria were Ralstonia and Pseudomonas. We suggest that, as a result of years of benzalkonium chloride treatments, the indigenous microbial community has been replaced by microbial populations selected by biocide application.
Heterotrophic microorganisms in deteriorated medieval wall paintings in southern Italian churches
2008
The Campania region in southern Italy is noted for its large number of churches that harbour invaluable frescoes, dated from the beginnings of the 4th up to the 13th century. The wall paintings represent an integral part of the monuments, and their deterioration constitutes a potentially significant loss for the world's cultural heritage. Heterotrophic microorganisms such as bacteria and mould can grow on the surface of paintings that contain a wide range of organic and inorganic constituents, and provide different ecological. niches that are exploited by a large variety of microbial. species. We isolated and identified the heterotrophic microorganisms found in the biodegraded medieval wall…

I DIPINTI MURALI STACCATI: CRITICITÀ E NUOVE PROPOSTE
2015
La tesi di Laurea Magistrale a ciclo unico, in "Conservazione e Restauro dei Beni Culturali", della Dottoressa Nicoletta Chiparo, riguarda l'intervento di restauro di un lacerto di dipinto murale staccato, di età paleocristiana, raffigurante un'orante; l’approccio alle problematiche di conservazione del dipinto murale ha suggerito l’avvio di una ricerca bibliografica e di laboratorio sui materiali per la realizzazione degli strati di sacrificio per i dipinti murali staccati. Il dipinto murale, di provenienza incerta e delle dimensioni di cm. 60 di h, cm. 41.5 di larg. mm. 1-3 di sp., rappresenta una figura femminile orante che, per la resa del volto, dei particolari dell’acconciatura e la c…
