This paper discusses the Mithraic reliefs found in Etruria (Regio VII). The reliefs are analysed and their iconographic, archaeological and chronological features compared with a view to advancing new proposals on the cult of Mithras in the area concerned. The paper focuses first on the new Mithraic relief discovered in Veii and discusses the presence of a specific object that constitutes the most original iconographic feature of the relief. It can be seen aligned behind Mithras' head, which obscures its central part: considering its shape and the presence of the quiver over Mithras' right shoulder, the object can be identified as a bow. The object's specific position, probably connected to the symbolic importance of the bow in the mysteries of Mithras, is unique not only among Mithraic reliefs but also in the surviving Mithraic evidence from the Roman world. The other reliefs from Etruria are analysed, with a brief description of the type of iconography, the chronology and archaeological context of each piece. Comparing the reliefs allows us to pinpoint differences in size, style and chronology, highlighting the uniqueness of the new relief from Veii. These differences can be put down to factors that are yet to be examined in more detail, connected to the clients and the workshops operating in the region. The study concludes that the Veii relief can be considered not only the oldest and most stylistically refined of these pieces, but also one of the earliest attestations of the cult of Mithras in Etruria.
