Jew-Ordinance, issued by Leopold IV, Duke of Austria, for the City of Freiburg im Breisgau [Present-day Germany]: “The attire of the Jews shall henceforth consist of coats and hats of the same color, except red or green. During Holy Week, they shall remain in their homes from Wednesday evening until the morning of Easter Monday, while keeping all windows and doors closed that are facing any Christian homes. Shall they encounter a priest on his way to bring the Holy Eucharist to a dying person, they shall immediately get out of the street. They are not allowed to charge any arbitrary interest on loans; at most, two pfennings per pound per week. They shall not take any suits of armor nor wet garments as collateral.”
