An example of this is the Monument of Lysicrates in Athens, albeit the spaces between the columns were walled in, even in ancient times. The Temple of Rome and Augustus on the Athenian Acropolis is a monopteros from Roman times with open spaces between the columns. Cyriacus von Ancona, a 15th-century traveller, handed down his architrave inscription: Ad praefatae Palladis Templi vestibulum.
