The archive presents 3D models of 11 globes — a subset of the library’s historic maps collection — that can be rotated and zoomed into for greater detail at every angle. This includes a stunning 1602 celestial globe by Dutch cartographer Willem Janszoon Blaeu, first produced in 1602. In addition to representing the constellations as their fantastic and mythological namesakes, it identifies a nova in the constellation of Cygnus which Blaeu had personally observed in 1600. It’s one of several celestial globes in the collection — some of which pair with terrestrial counterparts — and all of which are fascinating examples of globes that do not represent terra firma or spaces with fixed positions at all, and indeed capture only a brief moment in the relationship of celestial bodies.
