The
type can be more closely dated to early in 245, the other
types of the issue being
LIBERALITAS AVGG II,
P M TR P II
COS P P Emperor seated on curule chair, and
SECVRIT ORBIS.
The interpretation seems clear: the emperors have just arrived in
Rome from the East and distribute their second
largesse on the occasion. So we should date their arrival in
Rome to early 245. There is an
inscription generally taken to indicate that they were already in
Rome by July 244, but that interpretation is by no means necessary, in my opinion.
ADVENTVS AVGG is a common
type, but historically interesting, and that is certainly a
choice specimen of the
antoninianus!
