The Synagogue was associated with the devil in the Middle Ages

Ecclesia and Synagoga is a double allegory of medieval Christian art symbolizing the superiority of Christianity over Judaism. The Church is represented there as a crowned queen while the Synagogue appears blindfolded and with a broken lance in her hand. This imagery marked by anti-Judaism has been declined since the ninth century in the form of sculptures, stained glass windows and paintings whose degradation led the Synagogue to be confused with the devil in the fifteenth century.
