I have terrible insomnia. So I've been wandering the web (its after 4am!) and I found an entire high-res version of
Artforms of Nature by Ernst Haeckel on flickr. There is also a link to download the entire book as a pdf. I'm very happy. My hard copy version of this book seems to be an abridged collection and is missing many of the illustrations.
Artform of Nature by Ernst HaeckelErnst Haeckel was a German biologist and these illustrations were published between 1899-1904. I love them, so intricate and beautiful, yet also scientifically accurate.
