I would have to vote for
cross too.
On the final (?) version with
VOT /
XXXX it is clearly portrayed (as carasius noted) as a Latin
Cross with the lower
arm longer than the other three - this is the case on both examples despite being different
officinae and different dies. On the earlier versions it is more of a Greek
Cross with equal length arms though they all appear to have slightly longer lower arms to me. Perhaps if the
VOT /
XXXX one really is the latest then the
cross design was made more explicit on purpose.
The second interesting feature is the alignment of the
cross. It appears to be an X on most versions though that is also the way it would look if it was a
cross being held straight up in the hand - as Victory's arms is raised at roughly 45 degrees the
cross then appears as an X. However, on the example from
officina beta it is portrayed upright (incidentally in a nicer
wreath).
Taken together I think this means that a
cross was intended. This argument is consistent with all versions posted. It is meant to be a
cross held upright and at least one engraver decides to make that explicit (off. B). It is eventually lengthened to a Latin form to remove confusion from an X. If it was meant to be a numeral X then we have to postulate several errors in engraving. The off.B upright
cross and the two Latin form crosses.
As for what it meant? Not sure but it was a fun time for Christianity. Celebrations of Constantius' 35th started in 357 and appear to have coincided with
his visit to
Rome. While in
Rome in 357 the Arian Constantius issued laws (found as de episcopis ecclesiis et clericis in the Theodosian Code) confirming all privileges of the
Christian Church in
Rome. Interestingly during Constantius' visit he also bowed to public pressure and re-called the Catholic Pope Liberius, whom he
had replaced in 355 with
his own pro-Arian nominee, the "antipope"
Felix II. It is not clear exactly what position Constantius saw Liberius as having but in any event
Felix was pushed out of
Rome and relegated to obscurity. So there were enough high-level
Christian politics going on to mean that
cross could have
had some significance. An avowal that Constantius is in charge of religious matters and has the
Christian flock's best interests in mind?
