1911 Encyclopædia Britannica/Composite Order
COMPOSITE ORDER, in architecture, a compound of the Ionic and Corinthian orders (see Order), the chief characteristic of which is found in the capital (q.v.), where a double row of acanthus leaves, similar to those carved round the Corinthian capital, has been added under the Ionic volutes. The richer decoration of the Ionic capital had already been employed in those of the Erechtheum, where the necking was carved with the palmette or honeysuckle. Similar decorated Ionic capitals were found in the forum of Trajan. The earliest example of the Composite capital is found in the arch of Titus at Rome. The entablature was borrowed from that of the Corinthian order.
