arabic inscriptions look just like ruinic
obviously kaskara are a very early form if found in roman britain.

maybe he can 'discover' it was actually excalibur!
on another note,
hadrian's wall , built to mark and control trade at the northern border between the roman and celtic britains was dotted with forts, one of them,
Vindolanda, they recently found an underground armoury with examples of what we call
Lorica segmentata , as well as a lot of other stuff they are still meticulously sorting thru. they also found a lot of ordinary letters that had been thrown out onto the rubbish heap & partially burned. one of which was a letter where a legionnaire had written home for his family to send him some warm woolen socks and some new underpants. they have found a number of grave markers, one of which was in latin and aramaic where a syrian auxilliary centurion posted to the wall mourned the death of his british wife. rome was the original 'melting pot' of cultures. the wall was mainly manned by auxilliaries from all over the empire after they replaced the legions that originally built it.
the recent
King Arthur (2004) movie gives a flavour of life on the wall as rome abandoned its borders and drew in on itself. just don't take it too literally. the arms and armour while gussied up by hollywood were not bad, and i liked the drako standard arturus uses.
p.s. - i've got the 'director's cut' dvd's on my desk as i type, think i'll watch it again now that i'm thinking of it....
