For the first time, the complex, symbiotic ecologies that sustained the practices of two of the 20th century's greatest painters are revealed. With a shared rootedness in the natural world and its wondrous life forms, the work of Hilma af Klint and Piet 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 both elucidate and invigorate our understanding of two groundbreaking artists, and it will be sure to get synapses firing.
