" The holy relics were granted to Rainald von Dassel, Archbishop of Cologne (1159–67), following Emperor Barbarossa’s sacking of the city of Milan. Such a treasure was granted to the German Archbishop for his aid and chancellorship in service to the current Emperor. Not all were content to see such a treasure leave Italy…not without a struggle. —From L’histoire de la Sainte Empire Romaine     (The History of the Holy Roman Empire), 1845,     HISTOIRES LITTÉRAIRES "
