Walk to Canossa
Lambert's assessments, especially of Henry's Walk to Canossa, dominated the German historical image up to the times of the "Kulturkampf" in the nineteenth century. On the other hand, German historians trained in the positivistic methods of comparative source criticism taught that Lampert was a strongly biased, partisan writer who could not be trusted for an objective account of the reign of Henry IV. Oswald Holder-Egger himself called Lambert an outright fabulist in some instances. Scholars at this time held critical objectivity to be the highest value in a historical source and Lambert, along with many other medieval writers, failed to meet this standard. While they acknowledged Lambert provided important details for certain events and dates, his own view of history and opinions about some matters could not be accepted.
