It is the most complete Viking burial found in Scotland. Even the Coppergate dig in York didn't throw up anything as complete as this and I don't think Orkney has anything to compare despite being under Viking control until around 1200 or so. There is much Viking pottery as there is Anglo-Saxon from the same period but of course much further south in England. There are many Viking and Anglo-Saxon weapons. The Sutton Hoo treasure is probably the most complete and prized Saxon burial ever found. sutton-hoo.   http://www.archaeology.co.uk/the-timeline-of-britain/sutton-hoo.htm   

      

Probably one of the best examples of an Anglian sword was found bya child called Gary Fridd. (The Gilling sword)

There are many examples of Viking art (and Anglo-Saxon) if you care to look for it.
