 While the link between the Cimbri and the Zimmern family is fictional and only induced by the similar-sounding name, Froben recounts several episodes woven into a stream of historical information to prove it.The work also includes a complete fictional genealogy starting in the 10th century.Historical evidence is entered with the first actually known family member, Konrad von Zimmern, abbot of Reichenau Abbey from to 1255.
