Judensau

A Judensau (German for "Jews' sow" or "Jewish sow"), also known as Saujuden is a folk art image of Jews in obscene contact with a large sow (female pig), which in Judaism is an unclean animal, that appeared during the 13th century in Germany and some other European countries; its popularity lasted for over 600 years. In Nazi Germany, classes of German schoolchildren were sent to see the Judensau on German churches and the term exists as a neo-Nazi insult.

The Jewish prohibition against eating pork comes from Torah, in the Book of Leviticus Chapter 11, verses 2 through 8. The arrangement of Jews surrounding, suckling, and having intercourse with the animal (sometimes regarded as the devil), is a mockery of Judaism and example of antisemitic propaganda.

The image appears in the Middle Ages, mostly in carvings on church or cathedral walls, often outside where it could be seen from the street (for example at Wittenberg and Regensburg), but also in other forms. The earliest appearance seems to be on the underside of a wooden choir-stall seat in Cologne Cathedral, dating to about 1210. The earliest example in stone dates to ca. 1230 and is located in the cloister of the cathedral at Brandenburg. In about 1470 the image appeared in woodcut form, and thereafter was often copied in popular prints, often with antisemitic commentary. A wall painting on the bridge tower of Frankfurt am Main, constructed between 1475 and 1507 near the gateway to the Jewish ghetto and demolished in 1801, was an especially notorious example and included a scene of the ritual murder of Simon of Trent.
