Horse meat
In the eighth century, Popes Gregory III and Zachary instructed Saint Boniface, missionary to the Germans, to forbid the eating of horse meat to those he converted, due to its association with Germanic pagan ceremonies. The people of Iceland allegedly expressed reluctance to embrace Christianity for some time, largely over the issue of giving up horse meat. Horse meat is now currently consumed in Iceland, and many horses are raised for this purpose. The culturally close people of Sweden still have an ambivalent attitude to horse meat, said to stem from this edict.
