Very good condition! Das Silber und der Mond (1929) by Lili Kolisko is one of her key experimental works in the field of so-called capillary dynamolysis (“rising picture method”) and was created within the research programme of the Biological Institute at the Goetheanum. The publication appeared as an extensive portfolio issued by Orient-Occident Verlag and consists of approximately 80 pages of text accompanied by a remarkably rich visual component. It contains 20 textual illustrations and a set of 152 plates presenting experimental results, some of them in colour, including one multi-layered folded colour plate. In total, the book comprises roughly 170 illustrations documenting an extensive investigation into the relationship between chemical substances and cosmic rhythms. The study focuses on silver and its relationship to the Moon. Using experiments with silver nitrate and capillary rise processes on filter paper, Kolisko observed the formation of characteristic patterns, which she interpreted as expressions of formative forces linked to lunar cycles. Das Silber und der Mond thus represents not only an experimental scientific study but also a unique document of a period search for connections between natural processes and cosmic influences beyond the framework of conventional science.
