Leipzig and Wien, Verlag des Bibliographischen Instituts, 1899. Folio-sized sheet, printed on one side (36.3 x 27.3 cm). Lithograph.

A very fine, early lithographed plate, showing an amazing variability in the skeletons of the unicellular dinoflagellates. All are finely drawn by the author. Ernst Haeckel, a gifted artist, keen observer, and great zoologist, was the first to explore the riches of nature in microscopic forms, shapes, textures, and ornaments. This highly influenced the Art Nouveau and Jugendstil movements in the fine and applied arts. Some very light, strictly marginal toning, otherwise a very good, clean copy, with the printing delicate, yet strong.
