Abstract

The National Museum in Poznań (MNP) undertook research and restoration of a medieval sculpture Christ on a donkey. Research was underaken following detailed observation of the sculpture’s surface and interior as well as the X-radiographs. The examinations of wood fibres, grounds, pigments, binding materials and metals via microscopic and microchemical methods along with many stratigraphic cross-sections allowed the determination of the original polychromy under multiple underpaintings and to adopt an appropriate conservation program. The violet mineral fluorite was identified in the paint layer of Christ’s robe by microscopy and SEM-EDS analysis. This pigment was used most frequently in Central Europe (Southern Germany, Lower Silesia, Bohemia and Austria) during relatively short period (1470–1520). Based on the discovery of fluorite, we were able to confirm the earlier attribution of the sculpture to the workshop of Michel and Gregor Erhart of Ulm.
