Abstract

Green is an important colour in medieval Portuguese illuminated manuscripts. A certain deep saturated green, named bottle-green, is profusely used in Portuguese illuminations from the twelfth and first half of the thirteenth centuries. Historic reconstructions were performed in order to better characterize this green, using several copper salts as the source for colour. The experimental design was based on the material analysis of the greens found in manuscripts from the Lorvão monastery, namely by m-FTIR (Fourier Transform Infrared Spectroscopy) and m-EDXRF (Energy Dispersive Spectroscopy of X-ray Fluorescence) as well as by microscope observation. The glassy aspect of the green paints is evident under the microscope; like in a green glass, no grains are observed and the surface is of a deep homogenous and brilliant green. Selected medieval recipes, namely from “O livro de como se fazem as cores”, were reproduced and the results are compared to what found in the Lorvão manuscripts.
