(Band 1): mit acht und sechzig Kupfertafeln
An 1791 German natural history volume by Eugen Johann Christoph Esper, held by Heidelberg University Library, cataloguing marine corals and related zoophytes with copperplate engravings for naturalists and collectors. The plates show coral colonies drawn in fine hatched line with warm hand-tinted browns and reds, their branching forms, star-shaped polyp cups and ridged brain-like surfaces offering a designer studies of organic pattern, radiating structure and tonal line work.
