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.
