Year four of Tiberius's reign in Egypt — the regnal year indicated by the L Δ notation — places this piece in a period when Germanicus was touring the eastern provinces. His unauthorized visit to Alexandria in 19 AD, which Tiberius viewed as a deliberate provocation, deepened a rift that ended with Germanicus dead and the governor of Syria, Gnaeus Calpurnius Piso, tried for his murder. Alexandrian bronzes of precisely this regnal window circulated against that backdrop of imperial tension.
