Element forming part of the support system of the architectural structure, where the imposts are formed of columns.
The capital connects the top part of the column, which is circular in shape, with the flat straight area above, composed of the architrave. Its shape is normally a truncated pyramid to facilitate the load of the weight atop the columns.
The capitals are decorated according to the various orders of classical architecture, from Doric, the simplest, to Corinthian and composite.
The Corinthian capital is decorated with stylised acanthus leaves, carved from a single block of marble; it owes its name to the city of Corinth, where this architectural order developed in the 5th century BC, before it was used throughout the Hellenistic and later Roman periods, maintaining its characteristics even then.
