The oil painting was examined with visible light (VIS), raking light, ultraviolet (UV) and infrared (IR) light. In the paper, scientific methods such as High Performance Liquid Chromatography (HPLC), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) were used for pigment and binder analysis. In addition, dendrochronology analyzes were made for the chassis of the painting to determine the type and age of the wooden element. In conclusion, The dating of the oil painting has been reached after the analysis on both surfaces of the painting and the literature review of the the artist's colour palette.
