Painters from Venice, particularly Titian and Tintoretto, influenced El Greco’s fondness for expressive brushstrokes across the canvas surface. The legendary Saint Catherine’s Christian faith was so strong that she refused to marry a pagan Roman emperor; in retaliation, he ordered that she be tortured. Catherine was bound to a spiked wheel, but was freed when a thunderbolt from heaven shattered it. In this painting, she holds the martyr's palm while resting her left arm on a fragment of the wheel; her right hand grasps the sword with which she was ultimately beheaded.
