 Herman showed his loyalty to the Ottonian emperor both with the architectural concept of the building, which had an eastern and a western choir, and with the choice of the patron saint.The Ottonian emperors had a special veneration for St Laurence because on 10 August 955, the saint's feast day, Otto I won the Battle of Lechfeld against the Hungarians that had been regularly plundering Europe.At that moment Otto was the King of East Francia and after the victory the German lords raised him on their shields to celebrate his triumph and proclaimed him emperor.
