Two Viking Age trefoil brooches, from opposite ends of the Viking world. The intact one was found in Pskov, Russia, where a complete Viking Age dress was also found. The incomplete one was found in York. This was a popular Anglo Scandinavian pattern, and the motif is thought to have been based on the acanthus flower. The trefoil shape was based on Carolingian strap distributors, encountered by the Vikings while trading and raiding in France.
