Les laques de brésil dans l'enluminure médiévale : reconstitution à partir de recettes anciennes

Abstract : During a previous spectrophotometric study relating to the illuminations in a fifteenth-century manuscript attributed to the Boucicaut Master, we identified a red lake colourant which did not correspond to those usually mentioned by researchers. However, under the name 'brasil' it is well known in collections of recipes from the Middle Ages. The recipes for brasil given in these collections vary, as much by the processes of manufacture as by the ingredients listed. Taking our inspiration from some of these, we undertook the manufacture in the laboratory of various samples of brasil lakes. Each lake, applied as a glaze or in an opaque layer, was submitted to a battery of tests in order to assess the influence of the various constituents on the spectral and colorimetric parameters. These analyses were compared with a new examination of the illuminations in a manuscript housed in the municipal library of Châteauroux which gave us the opportunity to extend the field of research to two other illuminators of the same period, the Bedford Master and the Orose Master. Our results indicate that they all used brasil. Our study also attests to the importance of this colourant in the workshops of Paris during the years 1400-1420.
