I learn something every day about our Anselm Kiefer exhibition. I particularly learn something when taken round by Tim Marlow, our Director of Artistic Programmes, who knows so much about Kiefer from many years working with him at White Cube. He mentioned two key literary sources for Kiefer’s mythographic ideas. One is the writings of Robert Fludd, the early seventeenth-century Rosicrucian and cosmologist, who believed in a close connection between plants and the stars. The second is the poetry of Paul Celan, the Romanian-born, German-speaking Jewish poet and translator who settled in Paris after the war and whose best known work is Todesfuge.
