As Imhoof-Blumer argued in Revue suisse de num.
VIII, 1898, the epithet ENT or ENTI or ENTIX or ENTIXION, the Greek word for "Walled", on quite a few bronze coins of
Gordian III's Year 4 at
Caesarea suggests that
Gordian was responsible for providing
Caesarea with a city wall. Strabo, under
Augustus,
had called
Caesarea an "open city", i.e. unwalled; but
Procopius writes that
Justinian I (527-565 AD) replaced Caesarea's old walls with new ones. Presumably
Caesarea already
had walls under
Gallienus, since we are told that the city put up a long and brave defense before being captured by the Persian
king Sapor in 268 AD. The Persians
had been threatening invasion earlier, so there would have been
good reason for
Gordian III to fortify
Caesarea;
Gordian himself undertook two expeditions to
Syria to confront the Persians, in 239 and then again in 243, and died in Persian territory at Ctesiphon in 244 during that second campaign.
Imhoof-Blumer, and more recently
Sydenham with substantial supplements by Alex
Malloy and
Forvm member Pete Burbules, knew that epithet ENTIXION only on coins of Gordian's ET Δ=Year 4=241 AD at
Caesarea, but recently a similar coin from ET S=Year 6=243 AD turned up: see seller's picture below. It could be that this was just an old
rev. die of Year 4 that was
still available in Year 6, so
had its date altered from Δ to S and was used further; there seems to be a shadow of a Δ below the S in the
exergue. The protrusion engulfing the E of ET is not evidence of additional alteration, but merely damage caused by the application of the
countermark on Gordian's neck on the
obverse. AE 25-26 mm, 9.19 g,
