“Letter* of Protection to Jews (‘Judenschutzbrief’)” issued to Duke Heinrich of Slesia [Present-day Germany and Poland; Duchy of Silesia-Wroclaw]: “We, Henry [Heinrich] Duke of Silesia by the grace of God, […] announce publicly to everyone who sees, hears or reads this letter […] that the Jews shall pay us every year – for six [consecutive] years – three Mark (of interest), half of which is to be due on Walpurgis Night (April 30) and the other half on St. Michael’s Day […].” [Researcher’s note: The Duke’s helm seal (Helmetsiegel) hangs on a strip of parchment paper in dark wax of the original document. *Many of the ordinances and laws in the Early Middle-Ages were issued in the form of “letters.”]
