A Judensau (English: Jew pig) is an antisemitic art image of Jews in obscene positions with a pig that appeared during the Middle Ages in Germany and other European countries. Jews often wore a pointed hat (Jewish hat or Judenhut) during medieval Europe. There were many Judensau statues built onto churches.
In Martin Luther's Vom Schem Hamphoras dated 1543, Luther mentioned the Judensau from the Stadtkirche Wittenberg church:
"Here on our church in Wittenberg a sow is sculpted in stone. Young pigs and Jews lie suckling under her. Behind the sow a rabbi is bent over the sow, lifting up her right leg, holding her tail high and looking intensely under her tail and into her Talmud, as though he were reading something acute or extraordinary, which is certainly where they get their Shemhamphoras."
