Lorica segmentata from Caerleon

[Tarbicus]

We have found a fragment of what looks like scale armour, but rather than the usual Roman scale this is made of tiny copper circles that must have been pinned to a leather backing.

The method of attachment sounds like something Graham Sumner drew in Roman Military Dress (Arch of Constantine, colour plate Fig. 5), except that has squares, not circles, and the fastenings/rivets are visible (no overlap on the pieces).
