There are two types of capitals used at Hagia Sophia: Composite and Ionic. The composite capital that emerged during the Late Byzantine Empire, mainly in Rome, combines the Corinthian with the Ionic. Composite capitals line the principal space of the nave. Ionic capitals are used behind them in the side spaces, in a mirror position relative to the Corinthian or composite orders (as was their fate well into the 19th century, when buildings were designed for the first time with a monumental Ionic order). At Hagia Sophia, though, these are not the standard imperial statements. The capitals are filled with foliage in all sorts of variations. In some, the small, lush leaves appear to be caught up in the spinning of the scrolls – clearly, a different, nonclassical sensibility has taken over the design.
