Eden, Elysium, Arcadia, Utopia

In 1877, when the Italian astronomer Giovanni Schiaparelli drew the first detailed map of Mars, he imagined the planet as an earthly paradise. He labelled one region Eden, another Elysium, others, on later maps, Arcadia and Utopia. Peering through his telescope on the roof of the Palazzo di Brera, in Milan, Schiaparelli had seen what looked like oceans, continents, and water channels swim into view. “The planet is not a desert of arid rocks,” he wrote. “It lives.”
