RW: “M. Walbank (Walbank2003, pp. 346–347, n. 47, fig. 20.12:1) described the same iconography on an 18-mm coin minted at Corinth for Hadrian. According to Walbank, this particular iconography of seated Poseidon without a dolphin in his second hand revives one that first appeared on the duoviral issues of P. Tadius Chilo and C. Iulius Nicephorus in 43 or 42 B.C. The whole reverse type may represent a proposal for the Palaimonion’s statuary that was never realized, because a statue of the dead Palaimon atop a dolphin was finally adopted and appears on later coins. E. Gebhard (Gebhard1993, pp. 89–93, fig. 4) argued that the Palaimonion at the Isthmian Sanctuary under Hadrian was directly east of the temenos of Poseidon; this coin would seem to portray that building.“
