Judensau

The image appears in the Middle Ages, mostly in carvings on church or cathedral walls,[1] often outside where it could be seen from the street (for example at Wittenberg and Regensburg), but also in other forms.

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.

An inscription reads "Rabini Schem HaMphoras", Latin (in German orthography) for "Shem HaMephorash of the Rabbi", mocking the Tetragram to be a pig.

In 1988, on the occasion of the 50th anniversary of the Kristallnacht, debate sprung up about the monument, which resulted in the addition of a sculpture recognizing that during the Holocaust six million Jews were murdered "under the sign of the cross".

[2]In July 2016, Dr. Richard Harvey, a Messianic (Christian) theologian from the United Kingdom, initiated a petition on Change.org to have the Wittenberg Judensau removed.
