The image shows a seated woman depicted from the waist up. She is positioned in a relaxed posture, slightly turned to her right, holding a sphere in her right hand. Her facial features are delicate and serene, with closed eyes and a gentle expression. Her hair is styled in an elegant manner, swept back and possibly held in place with decorative elements. She is wearing a classical garment with flowing folds and long sleeves, which drapes gracefully around her body. She holds a measuring compass in her left hand, resting on her lap. In the background, there is a textured pattern that resembles stone or a carved surface. At her feet is a set square.
