caption: The image shows an illuminated manuscript with a painting of a man sitting on a chair, holding a book in his hands. His face is clearly visible, with a peaceful expression and a serene expression. He is wearing a long robe and has a halo of light around his head. His hair is long and dark, and his eyes are closed in concentration. The background of the painting is a deep blue, and the text on the book is written in a golden font.
