In-situ technical study of contemporary painting from the heritage collection of the Universitat de València, Spain. Canvases and colorful landscapes by Manuel Moreno Gimeno

Abstract

The Universitat de València brings together artistic collections of great value that embrace more than five centuries of history (1499–2022). Among them, the collection of contemporary painting stands out for its diversity of artists, artistic techniques and themes. One of the aims of the Vice-rectorate for Culture and Society of the Universitat de València is the study, conservation and dissemination of its art collection, implementing innovative methodologies that will place these artworks at the research and transfer frontline. To achieve this, the Laboratory for Analysis and Diagnosis of Works of Art of the Universitat de València: Conservation, Legacy, InnOvation has recently optimized a multi-analytical artistic diagnosis approach that combines the use of multiband technical photography (MTP) with digital radiography, infrared reflectography (IRR) and hyperspectral camera. The noninvasive methodology developed for the studied paintings, belonging to different historical periods, is completed by using a portable X-ray fluorescence. The final goal is to obtain useful information on the composition and execution technique, issues of great interest for developing preventive conservation plans for the collections and for the design of innovative exhibition proposals of an immersive and accessible nature. This article presents the results obtained for three paintings that were made by one of the most unknown Valencian painters of the early 20th century, despite the great quality of his work: Manuel Moreno Gimeno (1900–1982). These paintings are part of the aforementioned art collection of the Universitat de València, and are housed at the Faculty of Medicine. In this study, the use of MTP, IRR and hyperspectral imaging techniques were combined with the analysis of the pictorial surface using a portable optical microscope and a portable X-ray fluorescence. The results obtained indicate that Manuel Moreno Gimeno developed a landscape painting technique that was very close to that of other Valencian painters of the early 20th century. The handling of light and color was achieved using a rich color palette that included numerous contemporary innovative pigment such as chrome or cadmium.
