Abstrakt: The sandstone head sculpture from the hillfort of Závist in the southern periphery of Prague has been subjected to a non-invasive survey by mechanoscopic and analytical approaches. A 3D model of a sculpture has been created using laser scanning and photogrammetry. A reconstruction of stonemason's working tools was derived from longitudinal and transversal sections of the traces on the head's surface. Further screening of the surface by handheld X-ray fluorescence identified increased contents of lead and tin suggesting a former intentional coloring of the sculpture's surface. Traces of gold could indicate that the surface was gilded. It was confirmed that the sculpture was originally not a part of a human figure, but was intended to represent only a self-standing head. The way of making as well as the nature of the original surface treatment has excluded the possibility that the stone head from Závist was a modern replica.
