I find these scientific drawings from the 19th century to be so very beautiful! Ernst Heinrich Philipp August Haeckel (1834-1919) was an eminent German biologist, naturalist, philosopher, physician, professor and artist. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of botanicals, animals, and sea creatures some of which are shown above. Read more. Thanks for stopping by the cottage for your arts and science lesson. ♥Rosemary
