Science Art: favorite image Petrus Plancius Instructing Students in the Science of Navigation, early 17th century

^{Click to embiggen}

The Age of Exploration included at least a little bit of schoolwork. Here are navigation students learning the ways of current and coastline. Their teacher, Petrus Plancius, was a cartographer and Calvinist minister who helped Henry Hudson explore what we now know as New York, helped set up the Dutch East India company, and created some of the first globes not of Earth but of the constellations visible overhead, including some seen only from the Southern Hemisphere.

Found in the Internet Archive’s Metropolitan Museum of Art collection, which is curiously less SFW than you’d expect.
