The oldest drawing specimen collection, Balaenoptera physalus Linnaeus, 1758 (OBS.296787995)

BLOG - Before the invention of photography, everything was explained by hand drawings that required naturalists to be able to draw to describe the specimens they documented. Scholars from taxonomy to medicine had to be able to sketch leaves to the human heart, this is why the academic world at that time had the subject of "art and science". A tradition that taxonomic drawings are accompanied by a measurement scale usually by placing a measuring tool in millimeters or centimeters or inches that supports scientific sketches has an identification context, but of course there are obstacles to having to document large specimens. I found a picture of a large specimen: Balaenoptera physalus (Linnaeus, 1758). Uniquely, the specimen with catalogue number: OBS.296787995 and stored at the Observation International, Aarlanderveen, Netherlands, is the oldest I have ever known. The shabby drawing with three folds and worn edges was made in 1547 or more than 500 years old. Previously I ...
