A Rococo painting

The picture is Madame de Pompadour by Frank Butcher ( Francois Boucher 1703-70). I love Rococo art for its lightness. In a Baroque portrait madame would have assumed a statuesque pose and a serious expression. Power would have been oozing out of every pore of her dear little person. There would have been lots of activity around her, such as partially dressed deities and the like doing allegorical things. The picture would have been stuffed full of decorative detail.
In Boucher's portrait madame is flopped diagonally across the canvas. There is a sense of informality, and the monochrome decor seems to fade into the background. The light garland of roses which decorate her dress are mirrored by the two roses at her feet. Is the painter suggesting she may be a fallen woman? Madame is smiling and is obviously a lady of leisure. She reclines and contemplates her book. Ordinary folk wouldn't have had any leisure time at all, and wouldn't have been literate. She seems to exude a quiet confidence without actually stating it. What a delightful picture.
