Here the results are reported on the multi-analytical study of the Belarusian icon ""Virgin Eleusa"" . The X-ray and luminescence studies revealed some interventions performed in different time periods. The materials of original painting as well as the materials of interventions were successfully characterized by spectroscopic techniques. Layer-by-layer Laser induced breakdown spectroscopy was used for elemental composition study of art materials. Fourier-transform infrared microspectroscopy was used to indicate the types of binding media in the grounds and paint layers as well as to identify the art pigments. A low concentration of cerulean and cadmium yellow in the upper paint layers were identified by Surface enhanced Raman scattering . Since cerulean and cadmium yellow are known to come into use in XIX cent., the SERS results played the crucial role for dating of some intervention.
