“Before maps, scholarly monks drafted mappa mundi, representations not just of geographical knowledge but also of the realms of spirit, of myth, and of imagination. Imperial Rome, then the center of power and influence, was placed at the center point of the most ancient of the surviving mappa mundi. Later, as medieval society turned to faith and away from empire building, this shift in beliefs was reflected in mappa mundi as the Holy City of Jerusalem replaced Rome as cartographic ground zero. Mappa mundi created a visual metaphor placing mankind into context in the physical world, and simultaneously in other, invisible worlds. Today, technology is opening up invisible worlds of information, data and communication.”
