An acroterion, acroterium, (pl. akroteria) [1] is an architectural ornament placed on a flat pedestal called the acroter or plinth, and mounted at the apex or corner of the pediment of a building in the classical style. [2] An acroterion placed at the outer angles of the pediment is an acroterion angularium ( angulārium means ‘at the corners’).
The acroterion may take a wide variety of forms, such as a statue, tripod, disc, urn, palmette or some other sculpted feature. Acroteria are also found in Gothic architecture. [3] They are sometimes incorporated into furniture designs. [4]
The word comes from the Greek akrōtḗrion (ἀκρωτήριον 'summit, extremity'), from the comparative form of the adjective ἄκρος, ("extreme", "endmost") + -τερος (comparative suffix) + -ιον (substantivizing neuter form of adjectival suffix -ιος). It was Latinized by the Romans as acroterium. [5] Acroteria is the plural of both the original Greek [6] and the Latin form. [7]
According to Webb, during the Hellenistic period the winged victory or Nike figure was considered to be "the most appropriate motif for figured akroteria.” [1]
