Vieira da Silva was a key figure within the field of expressive abstraction in post-war Paris. However her work always retained a strong basis of reference to the visible world. Many of her paintings depict labyrinthine interior spaces, with complex or multiple lines of perspective. The elaborate mosaic and tiled surfaces recall the domestic architecture of her native Portugal. This picture was first exhibited in 1950 as The Corridor, but later became known as The Grey Room.
