The painting shows Saint Victoria (a martyr) who lived in Rome during the time of Emperor Diocletian. It was probably created together with the foundation of two side altars by father Walenty Bańkowski, when he was a parish priest in Biórków Wielki (1777-1801). Unfortunately, archival sources do not reveal its author.
