The Tuscan and the Composite orders are the two orders developed by the Romans. It is regulated by the Doric order, but with un-fluted support and a more simplistic entablature without triglyphs.
While moderately plain columns with circular capitals had been element of the inherent architecture of much of Europe and Italy since at least Etruscan structure, the Romans never considered this form to be a separate architectural form (for instance, the Roman architect Vitruvius never combine it adjacent his forms of the Greek Ionic, Corinthian and Doric orders).
