Re: need to identify 'ANCIENT' devices
I guess you from the UK but you have no idication on your ID. This is a typical UK selection. These are my thoughts:
1st Photo
Top Row (Left first) - 17th century spur buckle, rubbish, rubbish, late medieval thimble.
Middle Row (Left first) - 17th century sword belt hook (if broken at opposite end to loop), rubbish?, medieval locking pin, rubbish.
Bottom Row (Left first) - Could be Roman or Saxon plating, bronze bead (hard to date), Anglo-sandinavian 'kite' pinhead?, rubbish, can't see last one.
2nd Photo
Top (Left first) Part of a sword/dagger chape (but need to see back), Roman/celtic dagger pommel (should have iron deposits on end)
Can't see 2 objects.
Bottom - Saxon decorated piece.
In answer to the question, ancient history in the uk is prior to the end of Roman rule. Therefore 'most' of these items are not (some are) so the poll answer is "No" with abit of "Yes".
Hope this helps
