Terrestrial clockwork globe. Geographical details on the sphere suggest that the map of the globe is reminiscent of the early 17th century. Australia and New Zealand are missing and there is a hypothetical southern continent with 'Nouvelle guinea' connected to it. A total of four oceans are named. This puzzling terrestrial globe, which has the wrong spelling of 'TERESTRE' in the title cartouche and the wrong scale of the equator, deviates from the other terrestrial examples of the same size made by Fortin.

This may have been an early, unsuccessful attempt to make a globe, which Fortin passed to his clockmaker relation Augustin Fortin II to use as a clock globe in circa 1780. The clockwork mechanism connects the sphere to a geared wheel, which is driven by the brass clock movement.
