What separates the carved panel on the Athenian Treasury?

The carved panel on the Athenian Treasury is separated by an architectural feature known as a frieze, which often includes decorative elements like relief sculptures. This frieze typically runs along the upper part of the structure, distinguishing it from the lower sections and creating a visual hierarchy. Additionally, the use of columns or pilasters can further delineate the panel from other architectural components, enhancing its prominence and aesthetic appeal.
