Summary An unusually wide range of examination methods was applied to Botticelli's ‘Portrait of a Man with a Medallion’ to investigate its condition and technique before treatment. In addition to commonly used methods of examination such as X-radiography, XRF for pigment identification and IR reflectography (which confirmed significant changes to position of the sitter's hands), the more experienced technique of thermal infrared imaging was used to determine the extent of insect damange to the panel, while an endoscope allowed access to the back of the medallion (via a woodworm channel) and assisted in sampling the adhesive. The treatment included the consolidation of the medallion and of the panel. This was carried out so as to preserve historic evidence on the reverse of the panel. The selective thinning of the varnish and dirt layers with solvents dispersed in a wax emulsion is described and reasons are given for the decision to integrate the losses by imitating the colour and layer structure of the original painting rather than by using one of the more competitive systems of restoration.
