Which architectural order is used on the Arch of Titus?

Answer 1

The arch of Titus was the first example of a construction in the Composite order which combined both the Corinthian and the Ionic orders. The capitals are Corinthian, but with prominent Ionic volutes which projected laterally from the Corinthian acanthus foliage. The volute is a spiral scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column which was later incorporated into the Corinthian order to form the Composite column capitals. The acanthus is one of the most common plant forms used to make foliage ornament and decoration which was often used in the Corinthian order. The corners are articulated with a huge order of engaged columns which stand on a high basement. An engaged column is a column embedded in a wall and partly projecting from the surface of the wall. It was rare in classical Greek architecture, but it was favoured in Roman architecture and was commonly embedded in the cella walls of pseudoperipteral buildings. A pseudoperipteral building has free standing columns in the front (colonnaded portico), but the columns along the sides are engaged in the peripheral walls of the cella.
