With the benefit of hindsight Tacitus can single out a moment for emphasis that may seem trivial when viewed from a contemporary perspective. Claudius is the subject of one such moment in 20. Thanks are proposed in the senate to individual members of the imperial family for avenging the death of Germanicus. L. Asprenas draws attention to the omission of Claudius' name, and it is added at the end. Pondering the moment, insignificant in itself, Tacitus is struck by 'the mockeries made of mortal affairs in every business: in fame, in hope, and in veneration everyone was destined for imperial power rather than the future princeps whom fortune was keeping in hiding' (3.18.4). Tacitus clearly relished the irony of the situation, and it gave him the opportunity to glance forward in his work. In 20 Claudius had been forgotten, as he would later be in 41 before the discovery that resulted in his elevation to Empire; and his liminal presence under Tiberius prefigures his marginality in his own reign. Claudius' passivity will become the central feature of Tacitus' portrait of an emperor dominated by his wives and freedmen.
