These radiant images from the renowned 19th-century biologist and illustrator Ernst Haeckel, featuring marine microorganisms, will enthrall fans of his previous collections and garner-renewed attention for Haeckel s unparalleled artistry. From jewellery designers to scientists, graphic artists to naturalists, the range of people inspired by Ernst Haeckel s illustrations continues to grow. Following up on Prestel s Art Forms in Nature and Art Forms from the Ocean, this new collection features startlingly beautiful images created by Haeckel, who was commissioned to contribute to the report of the HMS Challenger expedition, which circumnavigated the world from 1872 76. The Challenger s achievements were unparalleled, with nearly 5,000 new species discovered and catalogued from the depths of Earth s oceans. Full-page reproductions bring these organisms colourfully to life, drawing readers into a world at once hypnotic and highly ordered. Divided into three sections Siphonophores, Medusae and Radiolarians these illustrations display Haeckel s remarkable artistic skill and understanding of the architecture of organic matter. The authors provide a brief history of the Challenger expedition, background on Haeckel s scientific and artistic accomplishments, as well as informative texts on each group of organisms. A guide to the natural world and an inspiration to artists of every stripe, this collection of Haeckel s work is a fitting tribute to a 19th century genius.
