Res Gestae

Then, when Mamertinus gave games in the Circus and the slaves that were to be manumitted were led in by the assistant master of ceremonies,[*](The consuls on entering office gave games lasting three days, and usually freed some slaves in the presence of the people.) the emperor himself,

with too great haste, pronounced the usual formula, that it be done according to law;[*](Manumitting slaves was a legal process, and the enactment was introduced by a formula; cf. Vopiscus, Aurel. 14 (of the adoption of Aurelian), iube lege agatur, fitque Aurelianus heres, etc.) and on being reminded that the jurisdiction that day belonged to another,[*](Probably to Mamertinus, as the consul giving the games.) he fined himself ten pounds of gold, as guilty of an oversight.
