According to the legend of "Three Handed St. Casimir", the artist (or two artists) who painted it originally depicted the King's right arm outstretched, but later wanted to change the composition. After painting the hand differently, he tried to paint over the failed part, but the hand miraculously did not 'stay' hidden and kept coming out, and the newly painted hand could not be painted over either. Thus, thanks to Divine Providence, the painting of St. Casimir was left with three hands. Restoration attempts to find out whether one of these hands with lilies was painted later, e.g. when the painting was renewed in 1594 (an inscription at the bottom of the painting indicates the work carried out at that time), have not yielded the expected results - although the painting has been slightly repainted several times (here, instead of the medallion with the image of Our Lady on the painting, the medallion with St Casimir's hand has been painted with the lilies). Casimir's chest with a chain with the Order of the Golden Fleece), all three hands were painted at the same time and were never painted over or otherwise altered.
