In 1899 German biologist, philospher and artist Ernst Haeckel began publishing Art Forms of Nature (Kunstformen der Natur), a series of detailed litographic prints, depicting the fantastic diversity of life. No life form is left out in this astonishing catalogue of illustrations of everything from mosses and lichens to plants and animals, on land and in water. Many of Haeckel’s theories have since his death fallen from grace, as for instance his dubious classification of human races. But Heackel’s artistic vision of nature has defenitely withstood the test of time, by merging science and art in a most beautiful way. All images are from Wikimedia.
