The composite order is a mixed order, similar to the Corinthian order in most respects, but with a capital that combines the volutes of the Ionic order with the acanthus foliage of the Corinthian. Not known in ancient Greek architecture, the composite order was invented in Roman times, probably in the late 1st century BCE, and revived in the Renaissance. Web resource here.
