The Greek and Italic orders appealed to the classical sensibilities, with defined uses and looks. This appealed to classical ideals of well ordered societies (like Plato’s republic). Further down the line in history, more free form architecture begins to take hold, manifesting in Byzantine, Carolingian and Romanesque capitals. These became much simpler, with many of the classical rules abandoned. Professor Han noted, the reintroduction of acanthus leaves on Romanesque capitals is reminiscent of Corinthian orders, referencing this return to classicism while also recognizing a visual distinction, being more abstracted and plain, which reflects the rest of the Romanesque style.
