Graduate work consists of the described conservation and restoration works on the polycromed wooden sculpture "Sv. Emerik" (St. Emeric) and the theoretical part in which a brief review of the theme of "The Three Kings" is presented through history. Sculpture "Sv. Emerik" was located in the Franciscan monastery in Cernik, on 27.10.2016. it was transported to the Department of Conservation and Restoration of Art (OKIRU). The sculpture was then transported to disinfestation by gamma radiation at Ruđer Bošković Institute, and returned to OKIRU where it was examined and photographed in detail. Then, historical-artistic research and the necessary conservation and restoration works were carried out. "Sv. Emerik", a polycromatized, gold-plated and silver-plated carved wooden sculpture from the 18th century, is the work of bishop Branjug workshop. Shows a young, chinless man in a standing position, he has a crown on his head, wide fur collar wrapped around his shoulder and ornamented mantle. According to the book "The Franciscans in Cernik",written by author Julije Jančula, the sculpture was in front of the previous (original) altar with the sculptures of the hungarian kings Stjepan and Ladislav and french king Ljudevit, but they were removed from the present altar of St. Peter and replaced with Tyrolean sculptures. Now these removed sculptures are left in the Franciscan monastery's pantry under inappropriate conditions. Sculpture "Sv. Emerik"is found in a relatively poor condition. There is a very small percentage of polychromy, gilt and silver plating of the original layer as well as overpaint. There are damage on the wooden carrier, visible wormholes, both forearms and parts of feet are missing. On the sculpture we find two chronological layers of gilding. Possible previous conservation and restoration works on sculpture are not found. Prior to the commencement of sculpture work, it was photographed. Conservation and restoration works were carried out in the so-called "Museum approach", which mostly involves only conservation procedures. The wooden caretaker of the sculpture was cleaned, parts of unstable polychromy are covered and cleansed, as well as gildes and chalk-animal glue background. The wooden carrier is in a relatively good and solid state, it is consolidated on the unstable parts. The Dino-Lite microscope examined the places of sculpture damage. Then micro-samples were taken for FTIR analysis. A brief review of the theme of "The Three Kings" throughout history is the theoretical part of this graduate thesis, which will briefly be described through historical periods and with an emphasis on iconographic descriptions.
