Mass poisoning episodes are attributable to consumption of grain \u2013 usually rye \u2013 infected with the fungus Claviceps purpurea. By focusing on possible cases of ergotism, we re-examine Norwegian history from the sagas through to the end of the seventeenth century. Our review \u2013 not intended to be exhaustive, or ex post facto to assign medical or psychiatric labels \u2013 draws attention to the very real possibility that many remarkable medical cases may have been the result of the ingestion of highly poisonous and psychoactive food substances. Where possible we highlight explanations given at the time \u2013 often rooted in religion or demonology \u2013 to explain the disease.<\/jats:p>","DOI":"10.1177\/0957154x11433960","type":"journal-article","created":{"date-parts":[[2013,2,19]],"date-time":"2013-02-19T08:56:36Z","timestamp":1361264196000},"page":"15-33","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Ergotism in Norway.
