For these were substituted later a set of stone columns resembling those in the proscenium of a theatre.
The proscenium was originally about 14 ft.
Proscenium arch survives, with top cresting, blocked by later inserted cinema screen.
The site has been excavated by the Greek Archaeological Society; it contained a temple, a sacred spring, into which coins were thrown by worshippers, altars and porticoes, and a small theatre, of which the proscenium is well preserved.
Behind this was a decorative, but false, proscenium on the solid rear wall of the auditorium.
