爱奥尼柱式
The Ionic order is also marked by an entasis, a curved tapering in the column shaft. A column of the Ionic order is nine times its lower diameter. The shaft itself is eight diameters high. The architrave of the entablature commonly consists of three stepped bands ("fasciae"). The frieze comes without the Doric triglyph and metope. The frieze sometimes comes with a continuous ornament such as carved figures instead.
