Argumentum Terrae   Fired and Unfired ceramic objects,   copper wire, clay slip             What makes Argia different from other cities  is that it has earth instead of air. From up here,  nothing of Argia can be seen; some say,  'It's down below there,' and we can only believe them.  The place is deserted. At night, putting your ear  to the ground, you can sometimes hear a door slam.        Italo Calvino, Invisible Cities
