coin hoard discovered in an unknown locality east of Saint Petersburg in Russia in 2019 ( tpq 1008/9), contained three Polish coins issued by Bolesław I the Brave of hitherto unknown types (Mikhel’son 2023). One of them bears the inscription: +POZZNANI, the oldest record of Poznań’s name, the then-capital center (Fig. 1). The reverse of this coin, like the two others, was struck from a die that contains the inscription: AЯЄAHLAT (Figs 1–3). This die was already known from the first die-chain of Bolesław the Brave’s coinage. This makes it possible to include the newly discovered coins in the die-chain. As a consequence, die-chain no. 1 can be expanded, its chronology can be made more precise (ca. 998–1010), and can help establish that the linked die-chains were used in the Poznań mint.

The subject examined in the article is the propaganda programme of emperors, members of the Constantinian dynasty, as documented by inscriptions and iconography of medallions. These the author proposes to analyse in the context of late-antique rhetoric texts (Orationes of Themisthius, Panegyrici Latini) and ideas of Eusebius Pamphilius contained in Vita Constantini. The conclusion furnished by this analysis is that the propaganda content broadcast in the works of rhetoric is closely related to the message communicated by the medallions and is an expression of a coherent ideological programme.
