Jorge Afonso: uma interrogação essencial na pintura primitiva portuguesa

O pintor Jorge Afonso (c. 1480-1540) ocupou cargos da maior importância e foi mestre de alguns dos mais importantes artistas da primeira metade do século XVI. Por laços familiares, por ligações profissionais, ou como representante régio no fornecimento e controle de empreitadas, esteve no centro das grandes obras artísticas do seu tempo. Fez uma carreira como oficial de armaria dentro da reestruturação manuelina, o que o tornou, também do ponto de vista simbólico, uma figura importante da corte do Venturoso. A Jorge Afonso são atribuídas as grandes tábuas da Charola do Convento de Cristo de Tomar, oito pinturas do mosteiro da Madre de Deus e o retábulo do Convento de Jesus de Setúbal. A dissertação reanalisa os dados biográficos do pintor, estuda as pinturas incluindo o seu desenho subjacente, e reelabora a compreensão da pintura portuguesa do tempo, vista sob a influência desta figura tutelar; ABSTRACT: Jorge Afonso. An essential quest on Portuguese primitive painting. Painter Jorge Afonso (1480-1540), held positions of major importance and was master of some of the most remarkable artists of the first half of the 16th century. By family links, by professional connections or as Royal representative for the supply and control of works, he was at the very center of the great artistic works of his time. He built a career as Herald what made him an important figure in King D. Manuel’s court . To Jorge Afonso are attributed the large paintings of the ‘Christ’s Convent’ Ambulatory in Tomar, eight paintings from the ‘Madre de Deus’ monastery and the ‘Covent of Jesus’ altarpiece in Setubal. This dissertation reanalysis the painter biographical data, studies the paintings including its underdrawing and reconstructs the understanding of Portuguese painting of that time, perceived under the influence of this tutelary figure.

Uncover the mantle: rediscovering Gregório Lopes palette and technique with a study on the painting “Mater Misericordiae”

Grego´rio Lopes (c. 1490–1550) was one of the most prominent painters of the renaissance and Mannerism in Portugal. The painting “Mater Misericordiae” made for the Sesimbra Holy House of Mercy, circa 1535–1538, is one of the most significant works of the artist, and his only painting on this theme, being also one of the most significant Portuguese paintings of sixteenth century. The recent restoration provided the possibility to study materially the painting for the first time, with a multianalytical methodology incorporating portable energy-dispersive X-ray fluorescence spectroscopy, scanning electron microscopy–energy-dispersive spectroscopy, micro-X-ray diffraction, micro-Raman spectroscopy and high-performance liquid chromatography coupled to diode array and mass spectrometry detectors. The analytical study was complemented by infrared reflectography, allowing the study of the underdrawing technique and also by dendrochronology to confirm the date of the wooden panels (1535–1538). The results of this study were compared with previous ones on the painter’s workshop, and significant differences and similitudes were found in the materials and techniques used

José de Escovar at the Chapel of the Souls: Technical and Material Study of a 1603 Panel Painting

This article reports the preliminary results of a technical and material study carried out on a 17th century panel painting located at the Chapel of the Souls in the main church of Vila Nova da Baronia (30 km away from Evora city, in southern Portugal). This painting is attributed to Jose the Escovar, a painter that worked for Evora Archiepiscopate between 1583 and 1622. Jose the Escovar is known by his mural paintings all across the Alentejo region. This is the first time that a panel painting made by this artist was studied. Analytical methods used included in situ technical photography (visible (Vis), raking light (RAK), infrared (IR), and ultraviolet (UV)), optical microscopy of cross sections, scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS), micro Raman spectroscopy, and micro Fourier transform infrared spectroscopy (m-FT-IR). The goal was to ascertain the techniques and colored materials used by Escovar on this painting so that the data can be used in future comparisons with others works attributed to this painter based on stylistic aspects.

MATERIAL CHARACTERIZATION OF GILDING AND PAINTING TECHNIQUES OF A POST-BYZANTINE ICON

This study aims to identify the materials used in the production of a post-byzantine icon from the Museum of Évora’s collection. The icon, representing the “Emperor Constantine and his mother Helen holding the Holy Cross” was once dated as being from the 10th century. Throughout a multi-analytical approach, combining area exams with spectroscopic techniques, this study tried to confirm its actual chronology. The results obtained revealed that it is most likely an icon from the late 17th or 18th century.

Calcium sulfate fillers and binders in Portuguese 15th and 16th centuries: Ground layers from a family painting workshop — Study by multianalytical spectroscopic techniques

This study presents results on a developed methodology to characterize ground layers in Portuguese workshops. In this work a set of altarpieces of the 15th and 16th centuries, assigned to Coimbra painting workshop was studied, overall the masters Vicente Gil (doc. Coimbra 1498–1525), Manuel Vicente (doc. Coimbra 1521–1530) and Bernardo Manuel (act. c. 1559–94), father, son and grandson, encompassing from late gothic to mannerist periods. The aim of the study is to compare ground layers, fillers and binders of Coimbra workshop, and to correlate their characteristics to understand the technical evolution of this family of painters, using complementary microscopic techniques. The cross-sections from the groups of paintings were examined by optical microscopy and the results were integrated through the analysis obtained by μ-X–ray diffraction, scanning electron microscopy with energy dispersive X–ray Spectrometry, μ-confocal Raman and occasionally with μ-Fourier transform infrared spectroscopy imaging. Ground layers are of calcium sulfate, present as gesso grosso (mainly anhydrite with small amounts of gypsum) in the first and last phases of the workshop and gesso mate (mainly gypsum with small amounts of anhydrite) in an intermediate period. Binders have protein and oleic characteristics.
