Abstract

Abstract

Introduction : The objective of the present investigation was to conduct a comprehensive analysis of the complex and intricate multilayered painting technique utilized by the Greek artist, Nikos Gabriel Pentzikis. The research expands upon previous research where the state-of-theart iTomography platform was employed in order to obtain a thorough understanding of the underlayers of three selected paintings using the Infrared Reflectography Imaging technique. The findings of this study revealed clear patterns in the artist’s unique technique, particularly in the underlayers of the second and third paintings, which presented significant results. The study highlights the importance of further exploration and investigation to gain a deeper understanding of the painter’s technique and overall oeuvre.
