The image shows a man in an upper body portrait. He is sitting in a slightly turned position, facing the viewer. He is wearing a wide-brimmed hat adorned with an ornate band, and his facial features include a prominent mustache and beard. His hair is not clearly visible due to the hat. The man is dressed in robes with an elaborate fur trim, a buttoned vest underneath, and his sleeves are gathered at the cuffs. He is seated in a chair with decorative elements on the armrest. In his right hand, he is holding a compass over a piece of paper on a table covered by a cloth. The background features a draped curtain suggesting an interior setting, and below the image is an inscribed plaque with writing.
