A frieze found in an entablature of a Greek or Roman building usually abides by certain rules. In Greek temples there are 3 classes: Doric (male), Ionic (female), and Corinthian (elaborate). The Doric frieze is divided into triglyphs (a divider with 3 horizontal lines) and metopes (either blank or containing a decorative sculpture). The Ionic order's frieze is either completely blank or completely decorated, there will be no breaks in traditional Ionic friezes. The Corinthian order was a well decorated frieze typically with action scenes throughout the entire length. Roman temples either copy a Greek order's frieze style (not always matching the entire order of building) or engrave writing into the frieze. A great example of this is the Pantheon.
