The marble-paved and colonnaded square in front of the Theatre, known as the Tetrastoon (Four Porticoes), was built in the first or second century AD, but its current form is due to a restoration in the AD 360s by a provincial governor called Antonius Tatianus. The west side of the square became at this time a place of honour for newly erected portrait statues of emperors and governors. Several were set up in the later fourth and fifth centuries. Two of these statues survive, one for Theodosius I or II and one for a governor called Flavius Palmatus.
