Entablature being called petrification. The structure of the entablature varies with the three classical orders: Doric, Ionic, and Corinthian.

Pure classical Doric entablature is simple. The architrave, the lowest band, is split, from bottom to top, into the guttae, the regulae, and the taenia. The frieze is dominated by
