San Juan was a 14th century priest and confessor to the queen of Bohemia. When Juan refused to divulge her confession to the queen’s jealous husband, King Wenceslaus, the king had Juan thrown off a bridge and drowned in the Moldau River. A miraculous light appeared over the place where Juan was drowned. In sacred art the saint is shown wearing a cassock, surplice, biretta and sometimes an ermine-trimmed cloak. He holds a cross and the palm of martyrdom.
