The Stoning of Saint Stephen [2], mural painting from the church of Sant Joan de Boí, around 1100, presents a lack of cohesion of the pictorial layer, with small specific losses and a stretching of the fabric that crosses the support. The tension that the pictorial stratum has, produced by the different products that have been applied over the years, provoked the instability of fragility of the painting. It is the first complete restoration of a transferred mural, with the research of new materials to elaborate the neutral colours - the areas without colour.
The antiquity of the original materials of the work, the restes which were added in a timely in surface and the tension caused by the thickness of the neutrals, where one of the factors that caused the inestability of the delicate condition of the painting, which suffered small losses.
The decision to intervene the work was taken because of these pathologies, following the process explained below.
Restoration by Mª Teresa Novell and Paz Marqués, with the collaboration of d'Anna Carreras and Àngels Comella.
