the 10th legion Fretensis–Antoniniana in Jerusalem

[Nathan Ross]

whoever is his source may have been misled by RIB 814 (Maryport)

Perhaps, although the theory also seems to involve Ireland and Abruzzo, so I think it's rather more developed than that!

Cornelianus is an interesting figure though - I came across him before when I was looking at officers who might have participated in the Bar Kokhba war (I suspect he didn't - the cohort command would seem more likely after the centurion position, I'd say, although we do have at least one case of a tribune switching to become a centurion, so who knows...)

The reading of the inscription does look a bit odd though. Here's a detailed picture of the stone. Is that U shape a symbol for 'Milliaria' then? Because otherwise it looks very much like it says To, or even Io (for Ioviorum?). And how 'Hispan[anorum] fits in the following line I don't know!

At least the [ ]etensis doesn't look like it could be anything else...
