Many scholars agree that the four large reliefs, each in two panels about three meters high, originated in a 30 meter long frieze in the Forum of Trajan. Two are on the short sides of the attic, and two more the most interesting and best preserved are within the central arch, nearly at ground level. Most authorities agree that they originally depicted Trajan and date to early Hadrianic times. Others have concluded that Domitian was the subject of the reliefs in the central arch, and that they somehow, like the Cancelleria reliefs, escaped mutilation during the two short periods of Domitian's damnatio. One objection to their originating in the Forum of Trajan is that it was reported to be still intact in the time of Theodoric, long after the Arch of Constantine was built.
