The panel painting represinting Madonna con bambino e San Giovanni of Museo Diocesano of Palermo: Scientific studies for the restoration
2017
The present research focuses on a painting on wood representing the Madonna con Bambino e San Giovanni, attributed to an unknown artist belonging to the Cretan-Venetian school, dated to the end of 16th century. The aim of the study is to provide a complete knowledge of the characteristics of the artefact in order to plane and perform a procedure according to conservative restoration. Historical and artistic evaluations and technical investigations were carried out for identifying the context, the constitutive materials and the executive techniques. The study was supported by the application of non-invasive (multispectral investigations and X-ray Fluorescence Spectroscopy) and analytical tec…
THE ‘CRUCIFIED AND DEPOSED CHRIST’ OF MUSEO DIOCESANO OF PALERMO, ITALY. SCIENTIFIC STUDIES OF A SICILIAN PAPIER-MȂSCHÉ POLYCHROME SCULPTURE
2022
In this paper we describe scientific investigations on the artwork ‘Crucified and deposed Christ’ from the Diocesan Museum of Palermo. Multidisciplinary studies were carried out to obtain interesting information about constitutive materials and executive techniques of XVIII century Sicilian papier mâsché, as well as about the sculpture state of conservation and the recognition of the previous treatments.Examination of the polychrome sculpture was both non-invasive (IRR, IRC, UV fluorescence, EDXRF spectroscopy X-Radiography) and micro invasive (optical microscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy SEM-EDX).SEM-EDX results showed the use of materials like…
Polychrome wood sculpture depicting The Madonna del Soccorso or della Mazza from the Archdiocese of Palermo: an integrated analytical approach for th…
2018
In this study the Madonna del Soccorsoo della Mazza wooden sculpture has been analysed by an interdisciplinary and integrated approach. The polychrome sculpture, dating back to the 18thcentury, comes from the church of the Madonna del Soccorso or della Mazza (1604) situated in Via Maqueda, in Palermo and it was placed on the main recess of the altar. All steps of the conservation project, from the preliminary study to the choice of materials and the restoration procedures have been accompanied and supported by diagnostic and scientific analysis. In order to evaluate the state of conservation of the sculpture and the technique employed to construct the support, computer tomography study was …
MULTIDISCIPLINARY STUDY FOR THE DATING AND THE RESTORATION OF THE SAN VITO WOODEN PULPIT OF MUSEO DIOCESANO OF PALERMO
2017
The aim of the present research is to investigate the execution techniques of San Vito wooden pulpit in the Museo Diocesano of Palermo and to provide helpful information to dating it in addition to technical, historical and artistic evaluations. In particular, this paper describes the application of analytical techniques (imaging diagnostics techniques, Scanning Electron Microscopy coupled with X-ray Energy Dispersive spectroscopy Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy and Fourier Transform Infrared Spectroscopy) to better understand the pulpit characteristics, both support and decoration, useful to plan and perform the correct restoration.
MICROSCOPIC TECHNIQUES AND A MULTI-ANALYTICAL APPROACH TO CHARACTERIZE THE MATERIALS OF TWO RUSSIAN ICONS
2018
Two 19th century Russian icons, from the Museo Diocesano of Palermo, were analysed by UV photography, X-ray fluorescence, energy-dispersive X-ray fluorescence (ED-XRF), optical microscopy, micro-Raman spectroscopy and Scanning Electron Microscopy, combined with energy dispersive x-ray analysis, (SEM/EDS). The multi-analytical study of the icons “Protezione della Madre di Dio” (Pokrov’s Icon, Protection of Holy Mother of God) and ‘’Madre di Dio Gioia di Tutti gli Afflitti’’, (Holy Mother of God, Joy of all the afflicted), have been performed to reveal materials and technological features of the original painting of the 19th century as well as the materials used during past restoration works.…
Multi-analytical study of the medieval wall paintings from the rupestrian church Grotta del Crocifisso at Lentini (eastern Sicily): new evidence of t…
2022
AbstractThis study presents the results of the examination and characterisation of the wall paintings that decorate the rupestrian church named Grotta del Crocifisso, which is located in the territory of Lentini (eastern Sicily, few tens of kilometres from Catania and Syracuse). The earliest mural paintings in the church date back to the twelfth century AD. A multi-analytical approach was adopted for the characterisation of stone materials, secondary degradation products, and pigments. For this purpose, the following techniques were used: reflected light microscopy (RLM), polarised light microscopy on thin sections (PLM), X-ray powder diffraction (XRPD), mercury intrusion porosimetry (MIP),…
Issues Related to the Restoration of Mirrors of the Wooden paliotto della chiesa del Santissimo Crocifisso all’Albergheria, Sicily (Italy)
2017
ABSTRACTIn this work, the decision-making process involved in the restoration of the eighteenth century paliotto ligneo (wooden altar frontal) della chiesa del Santissimo Crocifisso all’Albergheria of Palermo is presented. Earlier research concerning mirror restoration was based on only a few case studies and the proposed techniques were not suitable for the artwork here. As a consequence, it was necessary to re-examine theories and protocols of modern restoration to plan an appropriate intervention of the altar frontal. Since in this artwork the role of mirrors is not to give back images, as usual, but rather to create special light effects and play of lights, this work aims to find an app…
Anti-fouling additives for the consolidation of archaeological mortars in underwater environment: Efficacy tests performed on the apsidal fishpond of…
2020
This paper deals with the formulation of innovative mortars for the consolidation of archeological structures in underwater environment. The research was conducted within the frame of the MaTaCoS project (Advanced materials and technologies applied to the conservation of underwater cultural heritage) funded by MISE (Italian Ministry of Economic Development). The project concerns the design of advanced tools and methods for the protection of Underwater Cultural Heritage, through specific cleaning and consolidating procedures to be applied directly in situ. The fishpond of the archaeological site of Castrum Novum (Santa Marinella, Rome, Italy) was chosen as a pilot site for experimentation. I…
