The paper presents selected issues on the methodology of analysis of iconic messages drawing on the examples of paintings of Jaga Karkoszka. The analysis is based on the motive of interrelations between nature and culture. The author's approach is enrooted in late works of the Tartu School (esp. Jurij Lotman and Zara Minc), methods devised by Ervin Panofsky and contemporary ideas existing in aesthetics. Main thesis of the article states that notions applied by Roland Barthes to study photography (punctum and studium) are useful in analysis of other types of images.
