caption: The image shows a painting of a man wearing a black hat and a black dress, set against a white background. The painting is believed to be a self-portrait of Martin Luther, painted by Lucas Cranach the Elder. The man in the painting has a serious expression on his face, and his hands are clasped in front of him. His hair is dark and his eyes are focused intently on something in the distance. His clothing is simple and his posture is upright, giving the painting a sense of strength and determination.
