Physical Reality and Psychological Perception in Medieval Mural Paintings

In this Discussion,Beynac Virginthe context will be given that led to the multidisciplinary project (psychology, archaeometry) ‘The Virgin’s Blue Coat’, which subscribes to an ‘art and vision’ theme at the heart of current applications in the cognitive sciences and aims to study perceptive illusions manifest in certain Medieval mural paintings, propose different perceptive mechanisms and highlight the influence of higher-level variables, whether cognitive, developmental or social.

Some examples of these coloured illusions in various Medieval mural paintings of the Aquitaine region have raised questions both in terms archaeology and psychology.

In terms of archaeology and art history, it examines the use of colour during the Medieval era. Moreover, experiments on perception first require the acquisition of images of paintings or coloured ranges, to reproduce them as faithfully as possible and consequently take into account related problems, for example the alteration of pigments and the influence of sources of light.

In terms of psychology, the ancient use, and in varied semantic contexts, notably, of the illusion of simultaneous contrast puts into question, from the point of view of the observer, the automatic character of the perceptive and cognitive processes of the categorisation of colour, and provides rich investigatory material.

The Alba Museum’s (MuséAl) collection includes a monumental truncated male statue in white marble, discovered in 1992 in the cella of the axial temple of the Bagnols sanctuary. Dated to the end of the 1st century/beginning of the 2nd century AD, it certainly represents a heroised emperor. It will become the centrepiece of the museum collection.

However, the base of this fractured statue means that complex technical and aesthetic constraints must be taken into account. An in-depth and multidisciplinary study (conservator, conservator/restorer, archaeologist, historian, scientists from the CICRP and MAP/Gamsau) has thus been launched under the aegis of Aude Poinsot, director of the museum, integrating a detailed condition report, the critical review of the existing mounting solutions, of measurement of the speed of sound coupled with 3D modeling by photogrammetry and mechanical behaviour simulations.

Several mounting scenarios have been tested using models.

The whole study will be presented in the course of the Discussion.

Louis XIV Visiting the Gobelins Factory

Louis XIV Visiting the Gobelins Factory

Contributor: Jean Fouace, chief conservator of cultural heritage, head of the CICRP’s scientific department

The history of the Mobilier National and the Manufactures Nationales of the Gobelins, the Savonnerie and Beauvais are inextricably linked. Each of these structures has served to furnish the halls of power under different regimes since Louis XIV. Under the Fifth Republic the institution, even if its function has evolved, remains the true Furniture Warehouse of the Nation.

In the course of this Discussion, the history and the functions of the institution as well as the wealth of its collections will be touched on.

Issues and challenges in the restoration and presentation of a double-sided artwork

The Petit Palais museum has been working for many years in close collaboration with the CICRP and is offering the opportunity to the public to discover the scientific studies and restorations that the works have undergone, in the format of case study exhibits: the Case Studies of the Petit Palais. These case studies have been as successful in satisfying public curiosity and demand for precise and current information on the works as the request made by the Museums of France Heritage Department to refocus on the permanent collections.

The second piece of the series, ‘Popular piety in Italy in the 15th century. The banner of Saint Blaise by Niccolò da Foligno’, is dedicated to an important banner painted by Niccolò da Foligno. This piece, which has significantly enriched the collections of the Petit Palais museum, is part of the Campana collection given on permanent loan by the Louvre Museum in 1976. Probably commissioned by the brotherhood of Santa Maria del Vescovado of Assisi from the most accomplished Umbrian painter of the 15th century, this very large two-sided processional banner is the only example of this type of devotional object in France’s collections. It was awaiting restoration before being presented to the public.
