It is believed that the left wing of the diptych “Crucifixion” was written by the Dutch painter Jan van Eyck in the 20s of the 15th century. Other historians of Dutch painting of the early Northern Renaissance and researchers of the creativity of the brothers van Eyckov are inclined to refer this picture to the works of Hubert van Eyck. Although the red-blue color scheme used in the picture is more suited to the initial and middle period of the creation of Jan van Eyck.
