Heinrich (also Johann) Graess (Grass) was a native of Borken, Westphalia, Germany, and a teacher, was a "prophet" in the Anabaptist "kingdom" of Münster, who left Münster in October 1534 as an ambassador of Jan van Leyden, and was arrested at Iburg by the Bishop of Münster. He saved his life by promising to investigate and betray their military secrets to the bishop. He returned to Münster, leaving it a second time on 2 January 1535 to give the bishop the information, through which treachery a number of military projects of Jan van Leyden were prevented. The supposition that the "unknown messenger from Münster" who read Rothmann's book Van de Wrake before a meeting of Dutch Anabaptists in Waterland near Amsterdam is identical with Heinrich Grass (Doopsgezinde Bijdragen) is not very tenable.
