 The simpler examples were probably produced as a series from models prepared in advance, with the more sophisticated (and thus more expensive) diptychs reserved for the inner circle of the Roman aristocracy.The workshops responsible for their production were to be found in the Empire's two capitals at Rome and Constantinople, but the fall of the Western Roman Empire in 476 was probably responsible for the disappearance of western production at the end of the 5th century, with all surviving consular diptychs from the 6th century originating from Constantinople.The most common motif on 6th century consular diptychs from Constantinople shows the consul, standing, presiding over the consular games which marked his entry to the consulship.
