Æ21 - Marcus Aurelius ϹΥΡΙ ΚΑΒΙΡΩΝ

Syros was a minor Cycladic island of modest political weight, but its civic coinage under the Antonines reflects a community investing in local religious identity through the Kabeiroi — mystery cult deities whose worship had deep roots across the northern Aegean. The island's association with the Kabeiroi is not well documented in literary sources, making these bronzes among the few surviving attestations of the cult's presence there.

RPC IV.2 lists only a handful of specimens for this type.
