For the fi rst time, the complex, symbiotic ecologies that sustained the practices of two of the twentieth-century's greatest painters are revealed. With a shared rootedness in the natural world and its wonderous life forms, the work of af Klint and Mondrian celebrates the numinous spiritual power of nature and how this gives both art and life meaning. Including works never before seen in the UK, this publication will elucidate and invigorate our understanding of two ground-breaking artists and will be sure to get synapses firing.
