Historia Natvralis Ranarvm Nostrativm in qua omnes earum proprietates / Die natürliche Historie der Frösche hiesigen Landes
A natural history of native frogs, written and illustrated by August Johann Rösel von Rosenhof and published in 1758 in Nuremberg, with Latin and German text for a learned audience of naturalists. Its hand-coloured copperplates show frogs in their life stages, from tadpoles and metamorphosis to adults, eggs, and habitat plants, set on pale grounds with fine, even linework that a designer could draw on for botanical or amphibian motifs.
