The rivets along the border of this roundel indicate that it originally served either as a phalera, or, more likely, as the emblema of a vessel. The style of the raised border can be seen on separately-made vessel emblemae from the Hellenistic period. See, for example, the emblema with an acanthus floral, no. 92 in von Bothmer, A Greek and Roman Treasury, and the emblema with a satyr and a nymph on a dish, no. 53 in Oliver, Silver for the Gods. The placement of such emblemae on the interior of a dish designates it as a show-vessel, as its basic function would be compromised. For a gilt silver phalera with perforations near the border see no. 106, p. 176 in Marazov, ed., Ancient Gold: The Wealth of the Thracians.
