Quintus Aurelius Symmachus,  Relationes  9.3  (late fourth century A.D.):

Alii triumphis suis haec dona servuassent, ut posita lauru novic actoribus personarent Pompeiana proscaenium.

Others would keep these gifts for their triumph so that, abandoning the laurel wreath of the victor, they might make the theater of Pompeius ring with the voices of the latest actors.  (R.H. Barrow, trans.)
