From this vantage point you can see the complete nave arcade on the first
floor below you.  The light flooding in from the elevated windows brightly
illuminate the polished nave floor, creating a glittering effect of sharp
white reflection.  The obvious cross-shape of the arcade becomes clear from
this height, and illustates the non-secular background of the two Imperial
Residence architects, Tralles and Isidorus.  You can see several quick
residents scurrying up and down the nave, looking up curiously at you.  The
hallway continues east and west.
