An authentication case study: Antonio Palomino versus Vicente Guillo paintings in the vaulted ceiling of the Sant Joan del Mercat church (Valencia, S…
2012
In 1695, the Valencian artist Vicente Guillo was engaged in painting the vault of the Sant Joan del Mercat church in Valencia, Spain. After preliminary work was carried out, his contract was cancelled. In 1697, Antonio Palomino, renowned for the publication of his technical treatise entitled El Museo Pictorio y Escala Optica, was finally selected as the painter in charge of decorating the vaulted ceiling of Sant Joan del Mercat. This paper reports an analytical study focused on the characterisation and discrimination of the palette and painting procedures used by Palomino and Guillo in the frescoes of Sant Joan del Mercat. For this purpose, Raman spectroscopy combined with light microscopy,…
Multitechnique diagnostic analysis and 3D surveying prior to the restoration of St. Michael defeating Evil painting by Mattia Preti
2021
In this study, a multimethodological analysis involving optical and physical/chemical diagnostic techniques and 3D photogrammetric survey was successfully applied, for the first time, on the large oil on canvas St. Michael defeating Evil painting by Mattia Preti, located inside the Church of the Immaculate Conception of Sarria (Floriana) in Malta. Pigmenting agents, binder media, and raw materials were first characterized, both at elemental and molecular scales, through X-ray fluorescence spectroscopy (XRF), optical stereo microscopy (SM), scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared spectroscopy (FT-IR), and gas chroma…
All that Glitters is not Green
2012
The painter, carrying his easel, walks leisurely across the meadow that extends up to the limits of the summer sky. Under a chestnut tree he prepares his palette and his colors, then stretches and smiles. He is wearing a cotton shirt and slacks; a straw hat covers his curly hair. He walks barefoot because he likes the feel of the grass under his feet. This painter loves nature; he loves nature as an artist and as a scientist. This painter is a nuclear physicist, and his job consists in harnessing the elementary power of the atom, the one that makes the stars glow, in order to generate the power and hydrogen his town uses.
Joaquin Sorolla's pigment characterisation of the paintings ‘Vision of Spain’ by means of EDXRF portable system
2011
In this work, portable energy dispersive X-ray fluorescence (EDXRF) spectrometry was employed to the characterisation of the palette used by the Spanish artist Joaquin Sorolla (1863–1923) in the paintings ‘Vision of Spain’, a set of 14 oils on canvas painted by Sorolla between 1911 and 1919 by order of Mr Archer Huntington to decorate the library of the Hispanic Society of America (HSA) in New York. The analyses, sponsored by BANCAJA and provided by the HSA, were carried out in situ, prior to the cleaning and restoration process, while the paintings hanging on the walls of the library of the HSA. The results revealed that the paintings were made over different priming layers containing, res…
Aflame Face. The Sicilian Days of Carlo Levi.
2019
The seventy-three years of Carlo Levi’s (Turin 1902-Rome 1975) arch of life reveal his extraordinary coherency as an intellectual, his political flame, and his aesthetic versatility. His life was an expressive symbiosis with painting and writing: two forms of 'saying' amalgamated as one. If his love for Lucania is distilled from his journey to the South of Italy, his 'Sicilian days', framed in the Fifties, and preserved in his novel Words are Stones, radiate a subterranean and solar Sicily inhabited by violence and by Guttuso’s palette. The absorbing dynamism of the oxymoron governs the whole: that is, a spiritual, geological, social soul of a world, the peasant one, on the threshold of dis…
A class-separability-based method for multi/hyperspectral image color visualization
2010
In this paper, a new color visualization technique for multi- and hyperspectral images is proposed. This method is based on a maximization of the perceptual distance between the scene endmembers as well as natural constancy of the resulting images. The stretched CMF principle is used to transform reflectance into values in the CIE L*a*b* colorspace combined with an a priori known segmentation map for separability enhancement between classes. Boundaries are set in the a*b* subspace to balance the natural palette of colors in order to ease interpretation by a human expert. Convincing results on two different images are shown.
Investigation of modern oil paints through a physico-chemical integrated approach. Emblematic cases from Valencia, Spain
2020
Abstract The study and the characterisation of modern and contemporary oil paintings is still a challenging issue, in particular considering the significant changes in paint production across the 19th and 20th centuries. This paper presents the results of the first physico-chemical integrated study of the artistic materials used in six paintings from the School of Art and Higher Design of Valencia (Escola d'Art i Superior de Disseny, EASD-Valencia), artworks created between 1871 and 1943 by four famous Valencian artists: Salustiano Asenso Arozarena, Salvador Abril I Blasco, Enrique Navas Escuriet and Jose Bellver Delmas. A wide range of inorganic and organic compounds was identified through…
Multi-Technique Diagnostic Investigation in View of the Restoration of “The Glory of St. Barbara” Painting by Mattia Preti
2022
The present paper illustrates the results of a diagnostic investigation performed on the oil on canvas painting “The Glory of St. Barbara” (1680–1688) by Mattia Preti. The painting is located inside the St. Barbara Church in Taverna (Catanzaro, Italy), the city that gave birth to the artist. In situ, non-invasive studies, by applying X-ray fluorescence (XRF) spectroscopy, along with laboratory micro-destructive analytical investigations, by employing electron probe microanalyses (EPMA) coupled with energy-dispersive spectrometry (EDS) and micro-Raman (µ-Raman) spectroscopy, were combined to retrieve the color palette and identify the painting technique and style of t…
Enhancing visual literacy through interpretation of photo-genres: toward a genre typology of journalistic photographs
2016
ABSTRACTAlthough genre is one of the most extensively employed concepts in various disciplines, only a few attempts have been made to classify images in the press, providing either a palette of thematic categories similar to those of photography competitions or theory-based classifications, which often ignore certain types of photographs. In addition, no studies have suggested the genre typology as a tool for the interpretation of journalistic photographs. Based on a literature review and visual material analysis from the Polish daily Gazeta Wyborcza, this study compiles a typology that sets out four photo-genres: news photography, reportage photography, portrait photography and illustrativ…
