caption: The image shows a black and white drawing of a man with a long beard and a hat, believed to be David Greyser, a German theologian and theologian. He is depicted with a serious expression on his face, wearing a long robe and a pointed hat. His hands are clasped in front of him and his gaze is directed towards the viewer. His hair is long and dark, and his beard is full and well-groomed. He appears to be standing in a contemplative pose, as if he is deep in thought.
