The second booklet in the RADICETERNA series is dedicated to Katinka Bock. For the programme of research and the promotion of contemporary art that sees its first realisation in the Botanical Garden of Palermo, the German artist proposes a series of new works, especially conceived for the space of the Calidarium. Popolazione (lines and straight lines), is a composite sculpture inspired by and derived from residual natural elements of the Botanical Garden, collected and used as a base for forms designed by nature itself. The Calidarium in Palermo’s Botanical Garden, originally a heated greenhouse to allow certain plant species to survive the rigours of winter, takes on a new value as a place of care and an incubator of ideas thanks to the artists involved in the project, suitable for sheltering thoughts, experiences and narratives.
