A Roman glass phalera of Emperor Tiberius, early 1st Century AD [2800×2000]

See D. B. Harden, *Glass of the Caesars*, Milan, 1987, pp. 22-23, no. 2, for a similar glass paste phalera with Tiberius, Germanicus and Drusus the Younger. As Harden explains, “the medallion belongs to a closely-related group of glass objects that is associated with attempts to promote various members of the imperial family after the death of Augustus….The medallions were probably issued in sets of nine as parade decorations (*dona militaria*) to soldiers and were worn as phalerae on the breast-plate”.
