In a church built in Thessalonika a decade earlier, all the capitals were identical, but  St. Demetrios basilica was built with many kinds of capitals:  wind blown acanthus, and figurative types. This is a close-up of an eagle volute type. All the figurative types use the same acanthus pattern in detail. 

Hagia Demetrios
Thessalonika,
Greece
circa 480 A.D. 

This was a very influential church. Built from the beginning with capitals that did not match, and piers interspersed with columns on the nave. It was built right over the Roman bath where St. Demetrios was martyred in 303 A.D. It also houses some rare mosaics of Justinian's period that survived the iconoclasts.

Photo taken before the fire of 1917. Today, the church is rebuilt, but these marble revetments were lost. The columns and capitals on the lower level survived the flames.  Notice the top strip under the small moldings of the first storey revetments have the details of a full cornice done in antique perspective. Dark columns and mis-matched capitals are from the restorations due to fires in the 7th century. Like the mausoleum of Diocletian, the upper gallery capitals are the Ionic style. (Krautheimer)
