There are some „truths“ in reenactment which are rarely questioned, although maybe they should be. These are sometimes called „reenactorisms“, self-propagating myths that are perpetuated by the „monkey see, monkey do“ attitude that befalls reenactors, be they inexperienced or veterans.
One of those truths is a trivially sounding question: How long were viking-age belts? We have come to accept that they had a buckle and a strap-end, and the strap-end hung about crotch to mid-thigh – 20 to 40 cm from the buckle. The strap was fed through the buckle and then knotted just behind it, hanging straight down. This is sometimes called „the reenactor’s knot“, and there doesn’t seem to be an awful lot of evidence for it. Apart from that, it is really impractical because you constantly have a strap-end dangling between your legs. 😉
So, an excellent reenactor and designer of bronze jewelry replicas, Burr Öhrström, took it upon himself to research the Birka graves for evidence of belts and buckles. I did the same tonight (oblivious of the fact that he already had done that) and would like to systematize the conclusions a little.
