relatively little of the fanciful in our restorations of Persian
buildings, because the rock-cut tombs in the hillside still
reproduce in relief the vanished architecture of the plain below.

in enamelled brick actually ran round the cornice of the Propylaea,
we know that it would certainly not have been out of place.
The lintels, door-posts, and columns were of uncemented stone,
the beams of wood, and the remainder in brick.
