Our profile for Friedrich II von Hohenstaufen uses as background the Imperial Double Eagle of the Holy Roman Empire from the 15th century on. While it is widely recorded in the secondary literature that he supposedly used a Double Eagle as Emperor there is no contemporary record documenting this. The only description is by Matthaeus Parisiensis (1200 - 1259): scutum aureum, aquila biceps vel moniceps, nigra (golden shield with a double or single headed black eagle). The only depiction of a double headed eagle is the adornment to the description of Friedrich's death by the same author, a double eagle in an upside down shield (Stauferstele Castel Fiorentino). Should we remove the rather overpowering 15th century Imperial coat of arms?
