    The significant work of art, the Head of John the Baptist from Tajov, from the Museum of Central Slovakia in Banska Bystrica, which is probably part of the works of Niclaus Gerhaert von Leiden (1420/30 - 1475), was subject to conservation as well as detailed material analysis - first using non-invasive methods (radiography computer tomography, X-ray fluorescence), then laboratory analysis of taken samples (elemental and phase analysis, analysis of organic binders, dendrochronology, radiocarbon dating). The specific painting technique was described. Gilding of the head was performed without any ground only on brown preparatory layer for oil gilding (mixtion), however, the incarnates with an oily binder did contain a light dolomitic ground layer. The blood drops painting employed madder lake including sheep wool shearlings. The work consists of two parts - the head and the bowl, which was understood not to be original. Both parts are made from poplar wood. The results of the dating indicate that the head was created in the second half of the 15th century. The bowl could have been added later, but no later than the beginning of the 16th century. Its inclusion may have happened (albeit it is less probable) in the 17th century, but any period of time after that can be ruled out. The original colouring of the bowl was different the earth pigments of specific composition used in the ground layer imitated terracotta - a clay bowl. Based on the location of the existing hanging points the head was probably on display occasionally in a vertical position with a slight bottom view of 45 degrees.
