It shows a nude woman taking a sponge bath in an interior setting accompanied by a maid in a red gown. The woman preserves her modesty with a washcloth held in her left hand as she reaches with her right towards a basin placed on a side table. A convex mirror hangs from a central bar in the shuttered window above the basin and shows the reflection of both figures. In the tradition of such scenes, the mirror symbolises virtue and purity, while the dog in the lower center at the woman's feet – barely visible in the Fogg panel due to loss of paint, but more distinguishable in van der Geest's work – represents her fidelity. Her bedchamber is richly detailed; there is a wooden bed to the right, a tall folding chair against the back wall, and wooden beams running across the ceiling. An orange rests on the windowsill, and there are discarded
pattens on the floor in the lower left corner. Two other possible works by van Eyck of this style are known from descriptions only. In 1456, the Italian humanist
Bartolomeo Facio described a panel in the collection of Ottaviano della Carda, a nephew of
Federico da Montefeltro. In the panel, sometimes known as
Bathing Woman, the woman is attended by an older clothed maid as she emerges from her bath in a veil of fine linen which leaves only her head and breasts exposed. Facio's description includes details of a dog, a burning lamp similar to the one in the
Arnolfini Portrait, and a distant landscape visible through an open window. Facio mentions the innovative use of a mirror, which in the work is full length and reflects the entire back of the woman's body. ==Arnolfini portrait ==
