The Composite is partly based on the Ionic order, where the volutes (seen frontally) are joined by an essentially horizontal element across the top of the capital, so that they resemble a scroll partly rolled at each end. Despite this origin, very many Composite capitals in fact treat the two volutes as different elements, each springing from one side of their leafy base. In this, and in having a separate ornament between them, they resemble the Archaic Greek Aeolic order, though this seems not to have been the route of their development in early Imperial Rome.
