Silvered bronze, 7/8" diameter, of crisp spiral twist form. The spiral was so popular in Viking decoration that it is thought to be a mystical, form. Professionally conserved and the silver surface restored. On a modern black leather neck cord with gilt chain closure. Worn in numbers on the surface of the jerkin, these small metal brooches provided a measure of protection against sword cuts and, in fact, were a form of armor. See current Public Television programming for documentation of these in action. As protectors, they also held spiritual significance for the warrior. Surface textured from burial. Gift boxed with a certificate of authenticity.
