In Metamorphosis, filmmaker and media artist Pim Zwier chooses a highly original form to depict the life and work of the German artist Maria Sibylla Merian (1647-1717), whose study of insects laid the foundations of entomology. Her most important work revolved around the metamorphosis of caterpillars into butterflies: she recorded the process in beautiful prints and engravings and was the first to draw the insects in combination with the plant on which they live.
