The Vikings connection to Amanita muscaria

Is it possible that the Amanita muscaria played a role in the history of the Vikings? Paul Stamets seems to think so, check out this link for some cool pictures and insights.

“The Norse warriors were, according to legend, fierce fighters who were able to vanquish enemies with a fury in battle that gave rise to the term ‘bizerk’. Some think their fury was because of their use of Amanita muscaria; others vociferously dispute this. But…..I find that the handles of their swords bear a remarkable, and in some cases, taxonomically correct depictions of this mushroom. A coincidence or evidence ? I have eaten this mushroom, and the induced repetitive motion syndrome falls in line with this legend. The doubters might wish to rethink their skeptism, in my humble opinion. ” -P.Stamets ~
