"Mapmaking fulfills one of our most ancient and deep-seated desires: understanding the world around us and our place in it. But maps need not just show continents and oceans: there are maps to heaven and hell; to happiness and despair; maps of moods, matrimony, and mythological places. There are maps to popular culture, from Gulliver's Island to Gilligan's Island. There are speculative maps of the world before it was known, and maps to secret places known only to the mapmaker. Artists' maps show another kind of uncharted realm: the imagination. What all these maps have in common is their creators' willingness to venture beyond the boundaries of geography or convention."
