Heidecker is certainly not the first to see this divorce case as a turning point; both medieval and modern writers on the development of marriage have always referred to it, and the outpouring of letters, conciliar rulings, annals, and legal briefs at the time was large enough to fill an entire volume of the modern Monumenta Germaniae Histórica.
