According to tradition, it is associated with the Relief of Vienna. When, after the victory over the Turks, the army of King Jan Sobieski was returning to Poland, several soldiers stopped in Biecz. In gratitude for defeating the pagans and ending the war unscathed, the soldiers left this small portable altar in the church in Biecz.

The figure of Mary comes from the Crucifixion Group, which includes the sculpture of St. John the Evangelist, her pendant, also in the collections of the Museum of Ziemia Biecka. Initially, it was believed that both figures were placed on the rainbow beam of the Biecz parish church. However, their small size in relation to the parish space, according to art historians, excludes this view. They probably topped of one of the altarpieces.
