From the Renaissance to well into the nineteenth century, finely crafted, scientifically valuable, and aesthetically sumptuous terrestrial and celestial globes held a place of honour in the libraries and cabinets of curiosities of the aristocracy, wealthy merchants, and centres of research and learning. Over the past thirty years the Stewart Museum at the Fort in Montreal has assembled one of North America's most important collections of these now-rare and fascinating objects. In Sphæræ Mundi Edward Dahl and Jean-François Gauvin tell the stories of these globes, explaining their iconography and introducing us to the most important European globe makers of the seventeenth and eighteenth centuries.
