"Johannes Dantiscus, (German: Johann(es) von Höfen-Flachsbinder; Polish: Jan Dantyszek; 1 October 1485 – 27 October 1548) was prince-bishop of Warmia and Bishop of Chełmno (Culm). In recognition of his diplomatic services for Polish kings, the bishop and poet is also known as the "Father of Polish Diplomacy."
Johannes Dantiscus´ personal seal, a depiction located at Stanford University Libraries, identifies him as Ioannes De Curiis, Pruss. Varmien with St. Katherine, St. Jacob and St. Peter crests." - (en.wikipedia.org 31.01.2020)
