What does the Roman Empire have to do with the Stafford Knot?
I was watching a TV programme about Rome, and suddenly this image appeared - and I was able to take a photo of the TV screen.
SPQR simply means the 'Senate & People of Rome', and was the inscription carried on the Roman legionnaires' standards.
But I've not been able to work out what the knot shape above it in this photo refers to. (The programme was no help, and not even specific about where this plaque is).
It looks like a Stafford Knot to me; though I know it's probably not.
