The painting was created around 1700 and depicts Saint Roch, patron in the plague. Saint Roch lived in the 13th century. After the death of his parents, he gave away his property and went on a journey to Italy, where in many cities (including Acquapendent, Cesena and Rome) he served in hospitals and looked after the infected. Unfortunately, in the existing research on furnishing of the church in Korzkiew, in the absence of archival documents indicating the creators, no attempt was made to determine even a circle of potential authors of the reredos and its painting decor.
