Le Monde en sphères, a new exhibition at the Bibliothèque nationale de France, looks at spherical representations of the world throughout history. Globes, to be sure, but there are other spherical representations to consider as well. See the exhibition website (in French; buggy in some browsers) or visit the physical exhibition, which opens on 16 April 2019 and runs until 21 July at the François Mitterand building. Tickets €7-9.
