A crown from 700-780? Old enough for Charlemagne to have worn (if he did, which I'm very dubious about)? Decorated with a hammered-out Nail of the True Cross which is mysteriously non-magnetic? Used to be an arm-ring? And what does Wikipedia mean, two sections were lost? Lost HOW?
Anyone know any good sources to find out more???
*YES I was working. Though I'm buggered if I can remember what exactly at, it must have been a truly impressive clicktrail of distractions.
