Abbot Hatto (888–913) of the Monastic Island of Reichenau had a St George's Church erected, after he had received relics from the hands of Pope Formosus. The later Archbishop of Mainz made a major contribution to spread the veneration of Saint George throughout East Francia. The "Georgslied", a set of poems and hymns to Saint George in Old High German was composed on Reichenau island and the scholar Hermann of Reichenau wrote a "Historia sancti Georgii" in the mid-11th century, which today is lost.
