Atlas des Géographes d'Orbæ
The Atlas des Géographes d'Orbæ (Atlas of the Geographers of Orbæ) is a series of illustrated books written and illustrated by François Place and published in three volumes between 1996 and 2000. Presented as a geographic atlas written by the geographers of the lost island of Orbæ, the work comprises twenty-six chapters corresponding to the twenty-six letters of the Latin alphabet, each giving its shape and the first letter of its name to an imaginary country.
