Scottish-Polish Renaissance man Jan Jonston was a very talented artist, and despite being from the mid-1600s, some of his illustrations hold up remarkably well. However, he combined these keen anatomical illustrations with crazy made-up monsters and a madcap classification system. In Historiae Naturalis De Quadrupetibus (roughly equal to Tetrapoda) an armadillo is mysteriously grouped with turtles, which is extra-strange since armadillos show up in two other places. Even stranger, Historiae Naturalis De Exanguibus Aquaticis (covering “bloodless” animals, basically marine invertebrates) has seaturtles on one plate. There’s also a very unique mixture between a polychaete worm and the legendary amphisbaena.
