In the context of the Doric order, the geison, or cornice, projects from the frieze. The frieze is the horizontal band that sits atop the architrave and is flanked by the cornice and the architrave below. The cornice serves as a decorative and functional element, providing a crowning feature to the entablature, which consists of the architrave, frieze, and cornice. This overhanging projection is important both architecturally and aesthetically, creating a visual separation between the structure of the building and the roof or upper elements.
Understanding the relationship between these components is crucial to appreciating the overall harmony and proportion characteristic of the Doric order. The cornice enhances the effect of the entablature by creating depth and shadow, which is an important aspect of classical architecture.
