caption: The image shows an open book with writing on it, which is believed to be a codex, a type of medieval manuscript. The paper is yellowed with age and the text is written in a neat, cursive script. The book is open to a page with a detailed illustration of a man in a suit and tie, holding a staff in one hand and a book in the other. The man is wearing a long robe and has a serious expression on his face, suggesting he is deep in thought. The background of the page is a light blue color, and the edges of the paper are slightly worn, indicating that it has been around for some time.
