Portico Of The Sanctuary Of Athena
At Pergamum, built by Eumenes II (197-159BC). Characteristic of the Hellenistic age are the combination of a Doric colonnade in the lower storey with an Ionic in the upper, and the relaxation of the rules governing the syntax of the orders (including the insertion of a Doric frieze within an Ionic entablature).
