Front view of the aula regia in Domitian’s palace in Rome. The drawing is in landscape format. Only the lower margin, drawn in ink, remains. Inscriptions appear on the reverse.
The drawing shows the throne room during an audience. The rectangular room is covered by a coffered ceiling. The walls feature a series of niches with statues. They are framed by Corinthian columns and surmounted by semi-circular arches. An attic, pierced with windows and adorned with engaged columns, crowns the whole. A semicircular apse, covered with a conch, stands at the far end of the room. It houses the emperor’s throne.
