Which of the following is NOT a Greek column order?

The Composite column order is not a traditional Greek column order; instead, it is a Roman adaptation that incorporates elements of both the Ionic and Corinthian orders. Greek architecture is primarily characterized by three distinct orders: Doric, Ionic, and Corinthian.

The Doric order is recognized for its simplicity and sturdiness, featuring a plain capital and a fluted shaft. The Ionic order, on the other hand, is more elegant and slender, distinguished by its volute scrolls on the capital. The Corinthian order represents the most ornate style, marked by an elaborate capital adorned with acanthus leaves.

The Composite order emerged later in Roman architecture, blending features from the earlier Greek styles, particularly the volutes of the Ionic and the ornate elements of the Corinthian. Therefore, while the Doric, Ionic, and Corinthian styles are foundational to ancient Greek architecture, the Composite order does not belong to the traditional Greek column classification.
