IKTINOS and KHALLIKRATES,PARTHENON,the temple of Athena Parthenos

• The Parthenon is a temple of the Doric order with eight columns at the façade, and seventeen columns at the flanks, conforming to the established ratio of 9:4. This ratio governed the vertical and horizontal proportions of the temple as well as many other relationships of the building like the spacing between the columns and their height.

• The cella was unusually large to accommodate the oversized statue of Athena, confining the front and back porch to a much smaller than usual size. A line of six Doric columns supported the front and back porch, while a colonnade of 23 smaller Doric columns surrounded the statue in a two-storied arrangement.
• The introduction of elements of the Ionic order in a predominately Doric temple was more dramatic in the development of a continuous freeze on the exterior wall of the cella. While the integration of Doric and Ionic elements on the same temple was not a new development in Greek architecture, it was rare, and bestowed on the Parthenon a delicate balance between austere and delicate visual characteristics.
