FRANKFORT, SYNOD OF, 794: A gathering convened by Charlemagne at Frankfort, attended, according to later writers, by 300 bishops from Germany, Gaul, England, Spain, and Italy, and two delegates of the pope. Fifty-six canons are ascribed to it, the most important being the first, condemning Felix and Elipandus, the leaders of the Adoptionists; and the second, condemning the decisions of the Second Council of Nicæa (787) concerning image-worship, which had been accepted by Pope Adrian I.
