SCIENTIFIC INVESTIGATIONS FOR THE RESTORATION OF SANTA CHIARA FROM THE SANTA CATERINA D’ALESSANDRIA MONASTERY IN PALERMO, ITALY
2022
The aim of this research was to assess the techniques and the materials used to realize the canvas painting Santa Chiara, from the Santa Caterina d’Alessandria Monastery and to verify the state of preservation, the possible decay processes and previous restorations. Consequently, an integrated analytical approach based on the use of non-invasive (diffused, indirect and ultraviolet light investigations) and micro-invasive techniques (optical microscopy, OM, scanning electron microscopy, SEM-EDX, Fourier- transform infrared spectroscopy FT-IR spectroscopy) were used. The oil painting on canvas dated XVI century: data suggests traditional painting technique, characterized by two priming prepar…

La rappresentazione dell'architettura in alcuni rivestimenti musivi di epoca medievale in Sicilia
2019
Nei mosaici che decorano le chiese costruite in Sicilia nel XII dai re normanni compaiono rappresentazioni di edifici. Tali rappresentazioni, come frequentemente accade in epoca pre-rinascimentale, condensano, per accostamento, diverse ‘viste’ dello stesso edificio. La presenza negli edifici normanni di pavimenti e manufatti lignei decorati secondo pattern geometrici, ha suggerito la ricerca di analoghi tracciati nei rivestimenti musivi. L’analisi grafica propone la presenza di quadrati e ottagoni stellati in un mosaico della Cappella palatina di Palermo che raffigura un padiglione coperto da una cupola. Many buildings are depicted in the mosaic panels that enrich the churches built in Sici…
Risk indexes evaluation in view of a new showcase designing of “L’Annunciata” by Antonello da Messina
2018
Museums are often hosted by heritage buildings, where the indoor thermal conditions are usually subjected to a free-floating regime, due to the difficulty of equipping them with HVAC systems that, generally, are highly impacting tools from a visual point of view. These technological tools, in fact, could conflict with the established arrangement of the works of art. This would represent a problem, since the indoor physical conditions of these premises must fall within the ranges of values suitable to ensure the safety of the works of art there exhibited. In addition, the increasing time spent by visitors inside museums (now offering various possibilities of leisure, ranging from the book sh…
Mortars and Plasters under the Mosaics and the Wall Paintings of the Roman Villa at Piazza Armerina, Sicily
2010
The Roman Villa at Piazza Armerina in Sicily, built in many successive steps over the 2nd and 3rd centuries A.D., is renowned all over the world for both the wealth and the refinement of its mosaic floors. In February 2007 the Regional Government of Sicily started a restoration project of the whole archaeological site. The systematic survey and study of all decorative elements highlighted the value of wall paintings, which until then were almost unknown except for casual approaches to specific problems of conservation, carried on without any relation to the far and away famous mosaics. This paper shows the results of a physical chemical investigation of the mortars used for both floors and …
THE DEPOSIZIONE PAINTING FROM S. CATERINA MONASTERY IN PALERMO, ITALY: A TECHNICAL STUDY ON A ‘TRASPARENTE’ PAINTING
2022
The article analyzes the Deposizione painting of Giovanni Patricolo from S. Caterina monastery in Palermo, a painting realized by a particular technique of artistic representation attested in the 19th century: the ‘trasparente’ paintings, a specific kind of ephemeral apparatuses. The focus of this study is to shed light on the practical functions and the chronological path of this work of art, connecting it with the specific executive technique of the manufact. Furthermore, this research was a preliminary study aimed at designing an appropriate intervention for the restoration and conservation of the painting and a proper valorization of this artwork.
Filling-in Gaps in Textured Images Using Bit-Plane Statistics
2008
In this paper we propose a novel approach for the texture analysis-synthesis problem, with the purpose to restore missing zones in greyscale images. Bit-plane decomposition is used, and a dictionary is build with bit-blocks statistics for each plane. Gaps are reconstructed with a conditional stochastic process, to propagate texture global features into the damaged area, using information stored in the dictionary. Our restoration method is simple, easy and fast, with very good results for a large set of textured images. Results are compared with a state-of-the-art restoration algorithm.
Restoration of Digitized Damaged Photos using Bit-Plane Slicing
2007
Digital image restoration aims to recover damaged zones of a digital image, using surrounding information. In this paper we propose a novel approach, based on bit-plane slicing decomposition, with the purpose to make information analysis and reconstruction process easy, fast and effective. Tests have been made on digitized damaged old photos to restore several classes of typical defects in old photographic prints.
