caption: The image shows a portrait of a woman in a black dress with a white ruff, painted by Jan van Eyck. The woman is standing in a dark background, her face illuminated by the light of the painting. Her dress is a deep black color, with a high neckline and long sleeves, and her hair is pulled back in a neat bun. She is wearing a delicate white collar and cuffs, and a white lace trim around her neck. Her hands are clasped in front of her, and she has a gentle expression on her face.
