Whether cirrus, cumulus, or stratus: endlessly changing and barely tangible, clouds in the sky have always fascinated humans. Since the early 19th century many artists have focused their interest on images of clouds, as can be seen in this richly illustrated volume of masterpieces by such diverse artists as Caspar David Friedrich, John Constable, William Turner, Claude Monet, Paul Cezanne, Vincent van Gogh, Ferdinand Hodler, Gustav Klimt, Emil Nolde, Rene Magritte, Edward Steichen, and Gerhard Richter. This publication attests to the sheer, endless number of associations that artists from the Romantic era to the present day have connected with the phenomenon of clouds; it spans the arc from the cloud as ornament to "Cloud Seven," from the "Discovery of Clouds" to artificially manufactured cloud formations, telling of metamorphoses and of "uncanny beauty," and even discovering the "cloud of sound."
