The image shows the upper body of a man seated and slightly turned to the right, looking directly at the viewer. He has an elongated face with a mustache and beard, short hair covered by a cap, and is wearing elaborate early 17th-century clothing with a ruff collar, a detailed cloak or robe, and a large medallion on a chain around his neck. He holds a quill pen over an open book in his right hand. The background features shelves of books, suggesting a library setting, and an emblem or coat of arms to the right. Latin inscription is above the image, and stylized English text is below, providing context.
