Nave

This is the NAVE where the congregation would stand
   + was lit by 32 silver hanging candelabra 





 Now, looking upward see the wooden beams that go all the way across the nave? 
That's typical of both pagan Roman + Christian basilica 

Just below the beams are a row of windows called the 
CLERESTORY which literally means the "clear storey"
    a storey of the bldg pierced by windows 

Pagan Roman basilicas also had a clerestory 
   But the Romans didn't invent this method of lighting al
      large hall.  They borrowed this from the Egyptians

(here we looked at the model of the Hypostyle Hall 
    of the Temple of Amon at Karnak as an example of
         Egyptian use of clerestory windows)
