Res Gestae

When Theodoric learned of it, he had Odoin beheaded in the palace which is called the Sessorium.[*](A building of unknown origin, situated at the extreme south-east of the Fifth Region, adjoining the Amphitheatrum Castrense. After the part outside the Aurelian wall was destroyed, the extensive inner section became an imperial residence by the beginning of the fourth century, and Helena, the mother of Constantine, lived there.)

At the request of the people he gave orders that the words of the promise which he had made to them should be inscribed upon a bronze tablet and set up in a public place.
