Abstract
The Hellenistic temple of Apollo at Didyma presents several unique features in its plan. In its exterior it resembles the typical large Ionic temple of Asia Minor with a double colonnade surrounding it, no opisthodomus, and a pronaos containing three rows of four columns each. But at this point the plan of the temple was modified in the strangest manner. For the pronaos does not lead by a great central doorway into the cella, but where the doorway should come, the worshipper entering the building found himself faced with a blank wall 1·495 rn high with above it a colossal opening 5·63 m wide. Consequently the worshipper in the pronaos could not even look directly into the sanctuary. Instead, just above his eye-level beyond the embrasure of this ‘window’ stretched the floor of a large room, 14·04 m by 6·73 m with its roof supported on two columns. Through this room's central door the spectator on ground level outside could catch a glimpse of the upper part of the naiskos in the inner court.
